Hi everyone,
I’m working on a project where I want to send data from an Arduino Pro Mini to a Raspberry Pi using LoRa 433 MHz modules.

I’m using a RFM96 (433 MHz) module on the Arduino side, and an InAir4 module on the Raspberry Pi.
On the Raspberry Pi, I’m running the lora_gateway script (from Congduc Pham’s project), with this command:
sudo ./lora_gateway –mode 1 –freq 433
The Arduino shows that it is sending messages correctly (I see them on the Serial Monitor), but the gateway doesn’t receive anything.

Everything seems properly connected, antennas are attached, and all LoRa settings match on both sides.

I don’t understand why the communication isn’t working.
Can anyone help me figure out what might be wrong?

Thanks a lot!
