蓝牙deviation和offset

频率范围
The LE system operates in the 2.4 GHz ISM band at 2400-2483.5 MHz. The LE system uses 40 RF channels. These RF channels have center frequencies2402 + k * 2 MHz, where k = 0, …, 39.

调制特性
The modulation is Gaussian Frequency Shift Keying (GFSK) with a bandwidthbit period product BT=0.5. The modulation index shall be between 0.45 and 0.55. A binary one shall be represented by a positive frequency deviation, and a binary zero shall be represented by a negative frequency deviation.
