#Meshtastic folks, I need your help! How do I take the bytes off the wire and decode it into a Python class?

I'm reading in "raw protobufs" (according to the docs) from MQTT, which gives me a byte string. The ParseFromString methods don't take a bytes object, they take a String.

I see that if I can get the bytes converted into a google._upb._message.Message object, there's a meshtastic.util.message_to_json() that will probably guve me what I'm looking for.

Nevermind, I found another MQTT topic that publishes the data in JSON! I was subscribed to the topic that gives out the raw data and didn't realize that the "publish in JSON format" option published in both formats; I thought it just wasn't working right since I was still getting the raw packets.

I'm still curious about how to convert the raw data, but it's no longer in my critical path.

No idea how you find your LoRaWAN application encryption key or if you can crack it.

but i have used python and c11 libraries for just LoRaWAN packet parsing.
