RF_ENUM RFSetRfParameters (RF_SAMPLE_SETTINGS setting)
This function configures the RF part of the chip (both TX and RX)
for different (predefined) data rate, deviation and modulation index
requirements.
RF_OK: The operation was successful
RF_ERROR_PARAMETER: Invalid parameter, operation is ignored.
