(G)FSK Get_Stats() command
Get_Stats(Status, NbPktReceived, NbPktCrcError, NpPktLengthError)
returns statistics information on the last received packet. Depending on the selected packet
type in Set_PacketType() sent prior to this function, the parameters for generic packets
are interpreted as below.

bits 7:0 Status[7:0]: see
bits 7:0 RssiPkt[7:0]: Average RSSI level over the received packet
Signal power = - RssiPkt / 2 (in dBm)
bits 7:0 SnrPkt[7:0]: Estimation of SNR over the received packet
SNR = SnrPkt / 4 (in dB)
bits 7:0 SignalRssiPkt[7:0]: Estimation of RSSI level of the LoRa signal after
despreading
Signal power = - SignalRssiPkt / 2 (in dBm)
