This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary receiver components to operate correctly even at very low SNRs. This work has been conducted at the Telecommunication Circuits Laboratory, EPFL.

Hello @LeeKoTo, there isn't an RSSI value computed, but you can get an estimation of the SNR of each frame. If you uncomment the line 5 of gr_lora_sdr/lib/frame_sync_impl.h "#define PRINT_INFO", and build again, the SNR estimation will get printed in the terminal as: [frame_sync_impl.cc] 1 CFO estimate: -0.00789291, STO estimate: 116.522 snr est: -5.07804
