Radio channel parameters
ExRPB transmits advertising telegrams within the 2.4 GHz radio frequency band (2402MHz
… 2480MHz) using the Bluetooth Low Energy (BLE) advertising frame format.
By default, ExRPB will use the three BLE advertising channels (BLE Channel 37, 38 and 39)
defined for transmission. The transmission of a radio telegram on these three advertising
channels is called an Advertising Event.
Use of different radio channels within the frequency band from 2402 MHz to 2480 MHz is
possible, see chapter 6.7.8.
The initialization value for data whitening is set as follows:
For BLE channels is set according to specification (value = radio channel)
For the custom radio channels the initialization value is equal to the offset from
2400 MHz (e.g. value = 3 for 2403 MHz)
Table 1 below summarizes radio channels supported by ExRPB.
