An open source project is a forever Work In Progress. Feel free to be constructive.

Default configuration is in:

ArduinoIDE/USBRFMApp/USBRFMApp/Defaults.h

You should change it before uploading it to your board, based on your hardware, though you can later change it through the web interface.
Values are in hexadecimal, i bet you can handle them.
The data structure is a compact object/array/binary model, i should write documentation for it and i will, the module where it is handled is called CDS, which stands for Compact Data Structure.

ArduinoIDE/USBRFMApp/libraries/CDS

The main goal is to work with a balance between

1. binary data
2. object data model, based in JSON
3. and limited RAM

TODO

There are many todo's, one example is: CAD (Channel Activity Detection) is not supported yet, if you want to implement it, it would be fantastic, if you don't know how, you can open an issue asking for implementation in the following repo: https://github.com/sandeepmistry/arduino-LoRa
