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

2. Objective

smartphone LoRa device connection - Android - USB - Arduino - LoRa

This project demonstrates how JavaScript, Arduino, Android can be applied to a real-world Internet of Things (IoT) problem.
