Unmarshal JSON function in repository github.com/brocaar/lorawan



I’ve been using the package mentioned in the title to parse, craft, sign, etc. lorawan packets, complementing a security tool.

There’s a function in the package that marshals a PHYPayload to a JSON string, which is very useful. Nevertheless, I couldn’t find functionality to unmarshal a JSON string into a PHYPayload struct. This function would allow me to create a lorawan packet in an easy readable way (from a JSON string) and I was wondering if it’s possible to implement it? If so, can you provide me any directions on how to figure it out?



This is not possible. The Binary to JSON is easy, however the way back is tricky as for some fields (like the mac-commands), you don’t know the types.
