How to get RSSI value in RN2483?

Hello everyone,

I am new to the LoRa technology and to the TTN. I just bought a RN2483 module. By reading the command datasheet I couldn’t find any function to get the RSSI value of the last received packet.

Any ideas on how to get this?

Thank you.

You can do a “radio get snr” to get the signal to noise ratio of the last RX packet, which I think is probably the nearest you can get to RSSI. From http://ww1.microchip.com/downloads/en/DeviceDoc/40001784B.pdf

Thanks for the reply @mikcatta.

I have tried this command a couple of days ago, but I was getting some error in the output, not sure what it was, I have to check again. But all the “radio get” commands were working fine, except this one.

Anyways, how accurately is it to calculate the RSSI like this, after getting the SNR value?

Srx=-174+10log(BW)+NF+SNR

Assuming the Noise Figure (NF) as a fixed value of for example 6dB.

Thank you in advance.
