Get_RssiInst() command
Get_RssiInst(Status, RssiInst) returns the instantaneous signal strength during
packet reception.
(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.
LoRa Get_Stats() command
Get_Stats(Status, NbPktReceived, NbPktCrcError, NpPktHeaderError)
returns statistics information on the last received packet. Depending on the selected packet

byte 1 bits 7:0 Status[7:0]: see Get_Status() command
byte 2 bits 7:0 RssiPkt[7:0]: Average RSSI level over the received packet
Signal power = - RssiPkt / 2 (in dBm)
byte 3 bits 7:0 SnrPkt[7:0]: Estimation of SNR over the received packet
SNR = SnrPkt / 4 (in dB)
byte 4 bits 7:0 SignalRssiPkt[7:0]: Estimation of RSSI level of the LoRa signal after
despreading
Signal power = - SignalRssiPkt / 2 (in dBm)
