When I was using the ThingsNetwork, there was a decoder function where you could enter your own decoder for parsing the payload before it was sent to an integrated backend server.
I have minimised the lora data packets so that they are transferred to the gateway with minimal airtime. However RAK7258 documentation talks about a decode function to decode the data in the built in loraserver before sending it to an external application server.
I have found the function but there is only one option: CayenneLPP.
How do I add my own CayenneLPP decoder? is there a file I am supposed to upload?
Or is there just a set built in decoder that doesn’t work with my data?
