wifi binding on imx6sl evk based board_81xamx.top

81xamx.top

We are having problem with board that is based on imx6sl evk and rtl8192cu (chip on wifi module is RTL8188CTV). The wifi module is on USB interface.
We integrated rtl8192cu driver from another package, we used manual supplied by realtek to integrate there driver into android (from zip file
RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip pdf file \android_ref_codes_JB_4.2\Realtek_Wi-Fi_SDK_for_Android_JB_4_2.pdf).


The driver is build as part of the kernel, not module. We used there's wpa_supplicant, that came with realteks package (wpa_supplicant_8_jb_4.2_rtw_r8680.20130821.tar.gz).


Package is from this site: http://www.realtek.com/downloads/downloadsView.aspx?Langid=2&PFid=48&Level=5&Conn=4&ProdID=277&DownTypeID=3&GetDown=false&Downloads=true

RTL8192CU for Linux/Android

Firmware is from this link: rtl819x - Linux Wireless


Using serial interface terminal, we tested the wlan0 interface,  we can bring it up, and get ip number:

We need to use dhcpcd wlan0 command, the suggested init.rs service doesn't work, but thats not the problem.


Our problem is that binding from android ui and kernel isnt working.

When we tried to turn on wifi, from Settings>Wifi in Android UI, the slider button can move and change to On state, but the message on display "To see available networks, turn WiFi on" is still there.

in logcat we get:

D/WifiService( 2363): setWifiEnabled: true pid=2363, uid=1000

After that we can't move slider back.

When we exit that menu and return, the slider is back in Off state.



Using wifi from shell, we can get all the other wifi networks:

We also added permissions for wifi in android ..


Please, ask me if you need more details, I kept track of all the changed done in the android and kernel.

Logcat with DBG for classes in wifi is also available.


Does anyone have any idea about this problem? Could you help us, please? We wasted a lot of time on this.

Yes, we manage to get wifi working. Here are info's in more detail, so if anybody else has problem ...


We build driver as part of the kernel:

vim kernel_imx/arch/arm/configs/imx6s_{yourdevice}_android_defconfig

CONFIG_CFG80211=y


CONFIG_MAC80211_MESH=y

CONFIG_MAC80211=y


CONFIG_HOSTAP=y

CONFIG_RTL8192CU=y

CONFIG_RTLWIFI=y

CONFIG_RTL8192C_COMMON=y

#CONFIG_RTL8723AS=m

CONFIG_USB_USBNET=y

CONFIG_NET_RADIO=y


vim device/fsl/{yourdevice}/BoardConfig.mk


BOARD_WIFI_VENDOR := realtek


WPA_SUPPLICANT_VERSION := VER_0_8_X


CONFIG_DRIVER_NL80211 := true


BOARD_WPA_SUPPLICANT_DRIVER := NL80211

BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl

BOARD_HOSTAPD_DRIVER := NL80211

BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_rtl


BOARD_WLAN_DEVICE := rtl8192cu


WIFI_DRIVER_MODULE_NAME := "wlan0"

WIFI_DRIVER_MODULE_PATH := ""

WIFI_DRIVER_MODULE_ARG := ""


WIFI_FIRMWARE_LOADER := ""

WIFI_DRIVER_FW_PATH_STA := ""

WIFI_DRIVER_FW_PATH_AP := ""

WIFI_DRIVER_FW_PATH_P2P := ""

WIFI_DRIVER_FW_PATH_PARAM := ""




We disabled p2p, since we dont need it:

vim device/fsl/imx6/{yourboard}.mk

PRODUCT_COPY_FILES += \

#frameworks/native/data/etc/android.hardware.wifi.direct.xml:system/etc/permissions/android.hardware.wifi.direct.xml


or

rm out/target/product/{yourboard}/system/etc/permissions/android.hardware.wifi.direct.xml


or just remount system partition:

root@{yourboard}:/ # mount -o remount, rw /system;

and remove xml:

root@{yourboard}:/ # rm /system/etc/permissions/android.hardware.wifi.direct.xml



edit:

root@{yourboard}:/ # busybox vi system/etc/permissions/required_hardware.xml

or

vim device/fsl/{yourboard}/required_hardware.xml

or

vim out/target/product/{yourboard}/system/etc/permissions/required_hardware.xml

<!--

    <feature name="android.hardware.wifi.direct" />

-->


If you use it as module, you will need to add it also in PRODUCT_COPY_FILES


You need to correct init scripts, leave just this lines:

(this is from: http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html )


You can do it directly to out folder:

vim out/target/product/{yourboard}/root/init.rc

or/and (rebuild the whole system):

vim device/fsl/imx6/imx6.mk


mkdir /system/etc/wifi 0770 wifi wifi

chmod 0770 /system/etc/wifi

chmod 0660 /system/etc/wifi/wpa_supplicant.conf

chown wifi wifi /system/etc/wifi/wpa_supplicant.conf

#wpa_supplicant control socket for android wifi.c (android private socket)

mkdir /data/misc/wifi 0770 wifi wifi

mkdir /data/misc/wifi/sockets 0770 wifi wifi

chmod 0770 /data/misc/wifi

chmod 0660 /data/misc/wifi/wpa_supplicant.conf

chown wifi wifi /data/misc/wifi

chown wifi wifi /data/misc/wifi/wpa_supplicant.conf


    setprop wifi.interface wlan0

    setprop wlan.driver.status "ok"

   #setprop wifi.ap.interface wlan0


#and also remove this lines:

#    mkdir /data/system/wpa_supplicant 0771 wifi wifi

#    chmod 0771 /data/system/wpa_supplicant

#    symlink /data/misc/wifi/wpa_supplicant /data/system/wpa_supplicant


you can read it in that blog link, about unix/android standard socket setup.



vim out/target/product/{yourboard}/root/init.freescale.rc

or/and

vim device/fsl/{yourboard}/init.rc


#this is the only supplicant service and dhcpcd service for wifi that we use:

service rtw_suppl /system/bin/wpa_supplicant -dd -iwlan0 -Dnl80211 \

    -c/data/misc/wifi/wpa_supplicant.conf

    socket wpa_wlan0 dgram 660 wifi wifi

    class main

    disabled

    oneshot



service dhcpcd_wlan0 /system/bin/dhcpcd -aABKL

    class main

    disabled

    oneshot


service iprenew_wlan0 /system/bin/dhcpcd -n

    class main

    disabled

    oneshot



To keep it clean (it doesnt effect wifi):

vim device/fsl/imx6/imx6.mk


PRODUCT_PACKAGES += \

       rtw_suppl               \



We needed to make a little change in wifi_realtek.c since our jb is 4.3:


vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c

int wifi_start_supplicant(int p2p_supported)

..

    wifi_stop_supplicant(p2p_supported);

….


int wifi_stop_supplicant(int p2p_supported){

    char supp_status[PROPERTY_VALUE_MAX] = {'\0'};

    int count = 50; /* wait at most 5 seconds for completion */


    if (p2p_supported) {

        property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);

        snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);

    } else {

        property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);

        snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);

    }



Our problem was wrong supplicant name in prop setup. And, when wifi starts it first stops supplicant, and it wasn’t able to transfer that info through system. It was quite fun tracking this problem.


vim ./frameworks/base/wifi/java/android/net/wifi/WifiStateMachine.java

mWifiNative.killSupplicant(mP2pSupported);

if(mWifiNative.startSupplicant(mP2pSupported)) {

                            setWifiState(WIFI_STATE_ENABLING);

                            if (DBG) log("Supplicant start successful");

                            mWifiMonitor.startMonitoring();

                            transitionTo(mSupplicantStartingState);

                        } else {

                            loge("Failed to start supplicant!!");

                        }



Here are more info:

Good luck with it and please let me know if you need more info.




problem/solution:



if you get this problem:

E/wpa_supplicant( 3159): Could not set interface wlan0 flags (UP): Unknown error 132


solution:

missing rfkill, error 132 means "operation not possible due to RFkill"

vim kernel_imx/arch/arm/mach-mx6/board-mx6sl_{yourboard}.c

static int mx6sl_shd_bt_power_change(int status){return 0;}

static struct platform_device mxc_bt_rfkill = {

  .name = "mxc_bt_rfkill",

};

static struct imx_bt_rfkill_platform_data mxc_bt_rfkill_data = {

  .power_change = mx6sl_shd_bt_power_change,

};


/* init function  */

static void __init {yourboard}_init(void){

     ...

     mxc_register_device(&mxc_bt_rfkill, &mxc_bt_rfkill_data);

}


problem:

E/WifiHW ( 2488): Unable to open connection to supplicant on "/data/system/wpa_supplicant/wlan0": No such file or directory

solution:

setup correctly in init.rc and init.freescale.rc scripts wifi and wpa_supplicant permissions and services.

  • Re: wifi binding on imx6sl evk based board
    igorpadykov Employee

    Hi, Zoran

    what Android was used, is it Freescale Android (link below) ?

     

    IMX6_JB43_110_ANDROID_SOURCE_BSP  : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite,

    i.MX 6Solo and i.MX 6Sololite Android jb4.3_1.1.0 0 BSP, Documentation and Source Code

     

    i.MX 6SoloLite Evaluation Kit

     

    Also very often WiFi modules have different firmware, so different drivers are needed, though module

    name may the same. Have you contacted Realtek for updated version of driver for this specific module ?

    • Re: Re: wifi binding on imx6sl evk based board
      Zoran Lukic Level 1

      Hello,

       

      Thank you for answering,

       

      Yeah, I wanted to add that info. It was JB4.3 and the Realtek porting for rtl8192cu driver is for JB4.2.

      Some more porting work was needed to be done that wasnt in the manual.

       

       

      Also we are currently working on nfs, there shouldnt be some permissions problem.

       

      We put every all firmware files in the root fs (nfs) just in case.

      but driver source it askes for:

      also, driver is build in the kernel, from boot:

      If we manual start dhcp for wlan0, we can get wifi ip address (in my previous post).

      When we manually call wpa_supplicant:

       

      wpa_supplicant -iwlan0 -c/system/etc/wifi/wpa_supplicant.conf -B

      we get this in logcat:

       

      --------- beginning of /dev/log/main

      I/wpa_supplicant( 2938): Successfully initialized wpa_supplicant

      E/wpa_supplicant( 2938): nl80211: Could not add multicast membership for scan events: -2 (No such file or directory)

      E/wpa_supplicant( 2938): Failed to initialize driver 'nl80211'

       

       

       

      In board config file:

      (./device/fsl/evk_6sl/BoardConfig.mk file)

       

      BOARD_WPA_SUPPLICANT_DRIVER  := NL80211

      BOARD_HOSTAPD_DRIVER        := NL80211

       

      in both

      ./external/wpa_supplicant_8/wpa_supplicant/android.config

      and

      ./external/wpa_supplicant_8/hostapd/android.config

      CONFIG_DRIVER_NL80211=y




      We didn't contacted Realtek yet, we believe that we have some binding problems with driver and android ui.


      Also, slider button for wifi in the Settings menu in the Android ui seamed not to be connected to Settings>Wifi button.

      I can move button in Settings menu, to On state. And the enter the Settings>Wi-Fi and the button is in Off state.

      Exiting Settings>Wi-Fi menu and entering it again, it shows that button is back in Off state.

      Toggling wifi button to Off state isn't possible, after it was set to On state by us.


      After moving the wifi button slider to Off state we get this in logcat:

      D/WifiService( 2401): setWifiEnabled: true pid=2561, uid=1000

      E/WifiService( 2401): Invoking mWifiStateMachine.setWifiEnabled

       

       

      in system/core/include/private/android_filesystem_config.h file we can see uid's

       

      #define AID_SYSTEM        1000  /* system server */

      #define AID_WIFI          1010  /* wifi subsystem */

       

       

      Do we need to register platform driver callbacks, but this is usb module, it shouldn't need that?

      Is it some nfs permission related issue with wifi?

       

      So, what do you think?

      • Re: Re: wifi binding on imx6sl evk based board
        Zoran Lukic Level 1

        building the driver as module also doesn't work ..

        we are pretty sure that it is to android binding with driver.

        we tried three different drivers for rtl8192cu.

          igorpadykov Employee

          Hi Zoran, I got advice from our expert:

           

          I had been reading about this issue and also i read the description from the client and seem

          there's some missing configuration which the client could try.

          First of all try to set BOARD_WPA_SUPPLICANT_DRIVER to WEXT in the Android BSP.

          Also you need to provide a proper wpa configuration file for your device.

           

          For more details check this reference:

          PaNiC Random Rant (or how we used to call it: .plan): Porting WiFi drivers to Android

           

          Hope this helps

          • Re: wifi binding on imx6sl evk based board
            Zoran Lukic Level 1

            Yep, I tried this link.

             

            In manual provided with rtl wifi driver, it states to use new nl80211 interface.

             

            BoardConfig.mk

            BOARD_WPA_SUPPLICANT_DRIVER=NL80211




            Problem is that Wifi slider switch cant be moved, but nothing happens, so some binding or some permissions are problem. This is done in nfs.

            When slider is moved to On position in logcat we get this:

            D/WifiService( 2401): setWifiEnabled: true pid=2561, uid=1000

            E/WifiService( 2401): Invoking mWifiStateMachine.setWifiEnabled

             

            there should be more data or some error or permission staff for wifi, after this.

             

             

            wpa_supplicant doesnt start automatically, but it is in init.freescale.rc script. It can start manually with nl80211 driver.

             

             

            WEXT, I will try this again, thank you. I am not sure it will work, i dont think the driver is problem. I can scan and get all networks in area, using shell.

              We have a similar setup and are having the same problems.  Right down to the same bogus IP address reported by netconfig after dhcpcd seems to believe it got an address from the DHCP server on my Access Point.

               

              Has there been any activity on this?

                Yes, we manage to get wifi working. Here are info's in more detail, so if anybody else has problem ...


                We build driver as part of the kernel:

                vim kernel_imx/arch/arm/configs/imx6s_{yourdevice}_android_defconfig

                CONFIG_CFG80211=y


                CONFIG_MAC80211_MESH=y

                CONFIG_MAC80211=y


                CONFIG_HOSTAP=y

                CONFIG_RTL8192CU=y

                CONFIG_RTLWIFI=y

                CONFIG_RTL8192C_COMMON=y

                #CONFIG_RTL8723AS=m

                CONFIG_USB_USBNET=y

                CONFIG_NET_RADIO=y


                vim device/fsl/{yourdevice}/BoardConfig.mk


                BOARD_WIFI_VENDOR := realtek


                WPA_SUPPLICANT_VERSION := VER_0_8_X


                CONFIG_DRIVER_NL80211 := true


                BOARD_WPA_SUPPLICANT_DRIVER := NL80211

                BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl

                BOARD_HOSTAPD_DRIVER := NL80211

                BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_rtl


                BOARD_WLAN_DEVICE := rtl8192cu


                WIFI_DRIVER_MODULE_NAME := "wlan0"

                WIFI_DRIVER_MODULE_PATH := ""

                WIFI_DRIVER_MODULE_ARG := ""


                WIFI_FIRMWARE_LOADER := ""

                WIFI_DRIVER_FW_PATH_STA := ""

                WIFI_DRIVER_FW_PATH_AP := ""

                WIFI_DRIVER_FW_PATH_P2P := ""

                WIFI_DRIVER_FW_PATH_PARAM := ""




                We disabled p2p, since we dont need it:

                vim device/fsl/imx6/{yourboard}.mk

                PRODUCT_COPY_FILES += \

                #frameworks/native/data/etc/android.hardware.wifi.direct.xml:system/etc/permissions/android.hardware.wifi.direct.xml


                or

                rm out/target/product/{yourboard}/system/etc/permissions/android.hardware.wifi.direct.xml


                or just remount system partition:

                root@{yourboard}:/ # mount -o remount, rw /system;

                and remove xml:

                root@{yourboard}:/ # rm /system/etc/permissions/android.hardware.wifi.direct.xml



                edit:

                root@{yourboard}:/ # busybox vi system/etc/permissions/required_hardware.xml

                or

                vim device/fsl/{yourboard}/required_hardware.xml

                or

                vim out/target/product/{yourboard}/system/etc/permissions/required_hardware.xml

                <!--

                    <feature name="android.hardware.wifi.direct" />

                -->


                If you use it as module, you will need to add it also in PRODUCT_COPY_FILES


                You need to correct init scripts, leave just this lines:

                (this is from: http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html )


                You can do it directly to out folder:

                vim out/target/product/{yourboard}/root/init.rc

                or/and (rebuild the whole system):

                vim device/fsl/imx6/imx6.mk


                mkdir /system/etc/wifi 0770 wifi wifi

                chmod 0770 /system/etc/wifi

                chmod 0660 /system/etc/wifi/wpa_supplicant.conf

                chown wifi wifi /system/etc/wifi/wpa_supplicant.conf

                #wpa_supplicant control socket for android wifi.c (android private socket)

                mkdir /data/misc/wifi 0770 wifi wifi

                mkdir /data/misc/wifi/sockets 0770 wifi wifi

                chmod 0770 /data/misc/wifi

                chmod 0660 /data/misc/wifi/wpa_supplicant.conf

                chown wifi wifi /data/misc/wifi

                chown wifi wifi /data/misc/wifi/wpa_supplicant.conf


                    setprop wifi.interface wlan0

                    setprop wlan.driver.status "ok"

                   #setprop wifi.ap.interface wlan0


                #and also remove this lines:

                #    mkdir /data/system/wpa_supplicant 0771 wifi wifi

                #    chmod 0771 /data/system/wpa_supplicant

                #    symlink /data/misc/wifi/wpa_supplicant /data/system/wpa_supplicant


                you can read it in that blog link, about unix/android standard socket setup.



                vim out/target/product/{yourboard}/root/init.freescale.rc

                or/and

                vim device/fsl/{yourboard}/init.rc


                #this is the only supplicant service and dhcpcd service for wifi that we use:

                service rtw_suppl /system/bin/wpa_supplicant -dd -iwlan0 -Dnl80211 \

                    -c/data/misc/wifi/wpa_supplicant.conf

                    socket wpa_wlan0 dgram 660 wifi wifi

                    class main

                    disabled

                    oneshot



                service dhcpcd_wlan0 /system/bin/dhcpcd -aABKL

                    class main

                    disabled

                    oneshot


                service iprenew_wlan0 /system/bin/dhcpcd -n

                    class main

                    disabled

                    oneshot



                To keep it clean (it doesnt effect wifi):

                vim device/fsl/imx6/imx6.mk


                PRODUCT_PACKAGES += \

                       rtw_suppl               \



                We needed to make a little change in wifi_realtek.c since our jb is 4.3:


                vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c

                int wifi_start_supplicant(int p2p_supported)

                ..

                    wifi_stop_supplicant(p2p_supported);

                ….


                int wifi_stop_supplicant(int p2p_supported){

                    char supp_status[PROPERTY_VALUE_MAX] = {'\0'};

                    int count = 50; /* wait at most 5 seconds for completion */


                    if (p2p_supported) {

                        property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);

                        snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);

                    } else {

                        property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);

                        snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);

                    }



                Our problem was wrong supplicant name in prop setup. And, when wifi starts it first stops supplicant, and it wasn’t able to transfer that info through system. It was quite fun tracking this problem.


                vim ./frameworks/base/wifi/java/android/net/wifi/WifiStateMachine.java

                mWifiNative.killSupplicant(mP2pSupported);

                if(mWifiNative.startSupplicant(mP2pSupported)) {

                                            setWifiState(WIFI_STATE_ENABLING);

                                            if (DBG) log("Supplicant start successful");

                                            mWifiMonitor.startMonitoring();

                                            transitionTo(mSupplicantStartingState);

                                        } else {

                                            loge("Failed to start supplicant!!");

                                        }



                Here are more info:


                root@{yourdevice}:/ # cat /data/misc/wifi/wpa_supplicant.conf

                  Hi All,

                   

                  I am working to bring up RealTeck USB wifi dongel on android 4.3 and kernel 3.0.35  below are steps I followed :

                   

                  1) I am building  drivers as modules, copying them to  /system/lib/modules/ and after that I added below lines in init.rc before wpa_supplicant service start.

                      insmod /system/lib/modules/cfg80211.ko

                      insmod /system/lib/modules/mac80211.ko

                      insmod /system/lib/modules/rtlwifi.ko

                      insmod /system/lib/modules/rtl8192c-common.ko

                      insmod /system/lib/modules/rtl8192cu.ko

                   

                  2)wlan0 interface is creating successfully in /sys/class/net/wlan0.

                   

                  3) After that I try to run below commands :


                  root@sabresd_6dq:wpa_supplicant -Dnl80211 -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf -dd -B ---> success


                  root@sabresd_6dq: wpa_cli ----> Able to scan the devices form command line .


                  But if I try to do from application I am getting below errors:


                  E/WifiHW  ( 2514): Unable to open connection to supplicant on "/data/system/wpa_supplicant/wlan0": Connection refused

                  E/wpa_supplicant( 3163): p2p0: Failed to initialize driver interface

                   

                  kindly help me to solve issues.

                   

                  Thanks In Advance,

                    Hello Ranganath,


                    You need to run wpa_supplicant as service (in init.rc or init.xxxxx.rc script).


                    Do you need rf kill ?

                    We removed it completely from our android system.

                        Are the service name and the name in the interface file same?

                         

                        vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c

                        static const char SUPPLICANT_NAME[]     = "rtw_suppl"; /* without p2p concurrent */

                         

                        and

                         

                        in init.rc or init.xxxxx.rc script

                        service rtw_suppl /system/bin/wpa_supplicant -dd -iwlan0 -Dnl80211 \

                            -c/data/misc/wifi/wpa_supplicant.conf

                            socket wpa_wlan0 dgram 660 wifi wifi

                            class main

                            disabled

                            oneshot

                         

                        You could add ALOGE to wifi_start_supplicant function, to get more debug data.

                         

                        p2p is another service and interface.

                         

                        Are the modules loaded ok, after booting?

                        Is the insert mod in the right place (you have on early-init, on boot, on fs), so maybe to make it as part of kernel, not modules, for start, to eliminate that.

                          Hi Zoran,

                           

                          Thanks for reply,

                           

                          1) Yes services names are same inside init.freescale.rc and wifi_realtek.c, kindly find below :

                           

                          static const char P2P_SUPPLICANT_NAME_REALTEK[] = "rtw_suppl_con"; /* p2p concurrent */

                           

                          service rtw_suppl_con /system/bin/rtl_wpa_supplicant \

                              -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf

                              class late_start

                              socket wpa_wlan0 dgram 660 wifi wifi

                              disabled

                              oneshot

                           

                          2) I added logs inside function wifi_start_supplicant function and it pass below condition which give confidence supplicant is running,

                           

                          if (pi != NULL) {

                                      __system_property_read(pi, NULL, supp_status);

                                      if (strcmp(supp_status, "running") == 0) {

                                          ALOGE("TMR supplicant running success");

                                          return 0;

                                      }

                           

                          3) Yes the modules are loading after boot in init.rc. Below is the result of lsmod,

                           

                          rtl8192cu 91079 0 - Live 0x00000000

                          cfg80211 149736 2 rtlwifi,mac80211, Live 0x00000000

                           

                          4)But it fails in wifi_connect_on_socket_path function inside condition

                           

                          ctrl_conn[index] = wpa_ctrl_open(path1);

                              if (ctrl_conn[index] == NULL) {

                                  ALOGE("TMR wifi_connect_on_socket_path inside if");

                                  ALOGE("Unable to open connection to supplicant on \"%s\": %s",

                                          path, strerror(errno));

                                  return -1;

                              }    

                           

                          By throwing error E/WifiHW  ( 2514): Unable to open connection to supplicant on "/data/system/wpa_supplicant/wlan0": Connection refused.

                          please help me to resolve issue.

                            This is P2P supplicant.

                            static const char P2P_SUPPLICANT_NAME_REALTEK[] = "rtw_suppl_con"; /* p2p concurrent */

                            or

                            Do you have rtw_suppl running on system?

                            Do you have this file in android fs:

                            /data/system/wpa_supplicant/wlan0 ?

                            I dont think this is correct path.

                             

                            What is your wpa conf file, after you start wifi?

                            Mine is:

                            root@shd_6sl:/ # cat /data/misc/wifi/wpa_supplicant.conf

                            update_config=1

                            ctrl_interface=wlan0

                            eapol_version=1

                            ap_scan=1

                            fast_reauth=1

                             

                             

                            /* PRIMARY refers to the connection on the primary interface                             

                            * SECONDARY refers to an optional connection on a p2p interface */

                             

                             

                            Did you made modification so that jni (android_net_wifi_Wifi.cpp)  can interface this driver?

                            vim frameworks/base/core/jni/android_net_wifi_Wifi.cpp

                            static jboolean android_net_wifi_killSupplicant(JNIEnv* env, jobject, jboolean p2pSupported)

                            {                        

                              return (jboolean)(::wifi_stop_supplicant(p2pSupported) == 0);

                            }

                             

                            In 4.3 wifi_stop_supplicant function has argument:

                            int wifi_stop_supplicant(int p2p_supported);

                             

                            also we have to add this (and some debug log):

                            vim hardware/realtek/wlan/libhardware_legacy/wifi/wifi_realtek.c

                            int wifi_stop_supplicant(int p2p_supported) {

                            .......

                                if (p2p_supported) {

                                    property_get("wifi.supplicant", supplicant_name, P2P_SUPPLICANT_NAME);

                                    snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, P2P_PROP_NAME, supplicant_name);

                                      ALOGE("p2p_supported wifi.supplicant=%s\n",supplicant_name);

                                } else {

                                    property_get("wifi.supplicant", supplicant_name, SUPPLICANT_NAME);

                                    snprintf(supplicant_prop_name, PROPERTY_KEY_MAX, SUPP_PROP_NAME, supplicant_name);

                                      ALOGE("wifi.supplicant=%s\n",supplicant_name);

                                }

                             

                             

                            If you do not use modules for rtl wifi, remember to add return 0; in wifi_realtek.c functions:

                            insmod,rmmod,load_driver,wifi_load_driver,unload_driver,wifi_unload_driver.

                                In init.rc file, you have to setup correct permission, group and owner:

                                 

                                mkdir /system/etc/wifi 0770 wifi wifi

                                chmod 0770 /system/etc/wifi

                                chmod 0660 /system/etc/wifi/wpa_supplicant.conf

                                chown wifi wifi /system/etc/wifi/wpa_supplicant.conf

                                #wpa_supplicant control socket for android wifi.c (android private socket)

                                mkdir /data/misc/wifi 0770 wifi wifi

                                mkdir /data/misc/wifi/sockets 0770 wifi wifi

                                chmod 0770 /data/misc/wifi

                                chmod 0660 /data/misc/wifi/wpa_supplicant.conf

                                chown wifi wifi /data/misc/wifi

                                chown wifi wifi /data/misc/wifi/wpa_supplicant.conf

                                 

                                 

                                Check this two folders and files in them:

                                /system/etc/wifi

                                and

                                /data/misc/wifi

                                  I am able to solve permission issue now wpa_supplicant is running in command line, but I fails when I try from settings app  below are logs:

                                    Did you restart device, always try to turn wifi on from Settings after reboot.

                                     

                                    Could you cat wpa_supplicant.conf file in /system/etc/wifi/ and also in /data/misc/wifi, they seamed to be same size, but a little too big :-) ?

                                    Here are mine:

                                          Hi Zoran,

                                           

                                          If I start wpa_supplicant and run svc wifi enable form command line its working, but it's not working form setting app.

                                           

                                          And I am not able to find any thing in  command line by typing below command,

                                           

                                          cat system/etc/permissions/platform.xml | grep -i wifi

                                            So, there is a problem with jni or some permissions.

                                             

                                            What is in the logcat?

                                             

                                            Do you have this:

                                            cat system/etc/permissions/required_hardware.xml | grep wifi

                                                <feature name="android.hardware.wifi" />

                                             

                                            there should be also android.hardware,wifi.direct or something like that. You could try it for now, without wifi.direct.

                                             

                                            Edit file

                                            vim ./frameworks/base/data/etc/platform.xml

                                            or directly in android /system/etc/permissions/platform.xml and add those lines

                                                This means that android is working correctly:-).

                                                 

                                                As I said, couple messages before, wlan0 isnt in

                                                /data/system/wpa_supplicant

                                                 

                                                I am not sure that there is even that directory.

                                                 

                                                In your wpa_supplicant.conf file, you set path to interface directory, but that path doesnt exist, and of course wlan0 file isnt there.

                                                 

                                                Please try with wpa_supplicant.conf that I've sent you before.

                                                        Do you have ethernet cable connected to the device?

                                                         

                                                        Do you supply enough current to the device?

                                                          No I don't have ethernet cable connected to device, but the wifi is connected via usb hub for my device.

                                                            Could you try without hub?

                                                             

                                                            Have you build driver as modules?  (remember return 0; for insmod in driver)

                                                             

                                                            Could you add LOG to see what is the command?

                                                              Yes I build driver as module and I am returning 0 form that.
