Computes the carrier frequency of the Bluetooth signal to generate based on the value that you specify in the channel number parameter. The toolkit computes the center frequency according to section 2, Part A, Volume 2 of the Bluetooth Specification Version 4.2.

The Bluetooth system operates in the 2.4 GHz ISM band. This frequency band is 2,400 MHz to 2,483.5 MHz. RF channels are spaced 1 MHz apart and are ordered in channel number k according to the following formula:

f = 2402+k MHz

where

k=0, 1, ..., 78 for Basic Rate/Enhanced Data Rate packets

f = 2402+(2*k) MHz

where

k=0, 1, ..., 39 for Low Energy packet

f is the frequency of the RF channels.
