The correct values selected in the table below must be carefully tested to ensure a good
detection at sensitivity level and to limit the number of false detections.
Set_BufferBaseAddress() command
Set_BufferBaseAddress(TxBaseAddr, RxBaseAddr) sets the data buffer base
address for the packet handling in TX and RX.
(G)FSK Set_ModulationParams() command
Set_ModulationParams(Br, PulseShape, Bw, Fdev) is used to configure the
(G)FSK modulation parameters for the sub-GHz radio. Depending on the selected packet
