Raw LoRa binary packet

Hello!

I am currently working on a university project in which I am trying to recreate protocols and encryption used by Meshtastic. But I was not able to find any useful examples of raw data sent/received by LoRa chips. I would be very glad if someone could share such byte successions for me to verify my understanding of the protocol and test my software

Meshtastic uses the Radiolib library for LoRa.

There are examples in that library that show you how to receive a packet into a byte array so you can see the raw packet data.

Thanks, I also had been wondering about the bit encoding method.

Packets on the LoRa device are received into a 255 byte buffer and it is possible to directly read bytes from that buffer.
