Receiving all data on a certain frequency


Is it possible to receive all data that is being sent on a fixed frequency ?
I have a RF keyboard that is sending signals at 868.50 MHz with GFSK modulation and I would like to receive them using and arduino + Dragino LoRa shield and the lmic library.
The signal is strong and I am able to see it using SDR# and my Airspy mini.

All help will be appreciated.

The LMIC is not really designed to do this. You might be able to modify the raw sample to do this, but one of the other low-level radio libraries (Radio Head?) (correction, thanks: Radiolib) might be a better choice.

I got it working with the RadioLib library.
