AT commands work fine with an external microcontroller. But I don’t want to use an extra microcontroller. How can I access the open source version of RUI 3 software?
Only these commands are defined in the LoraWAN AT Slave code that you have shared on your site before.
Hi @hans11 ,
The source code of RUI3 is not open source. But you can freely use all exposed APIs. Any functionality that you have via AT command can be done via RUI3 API.
To start with RUI3, you can follow this guide (if you are using the RAK3172 breakout board) RAK3272S Quick Start Guide | RAKwireless Documentation Center.
Btw, the AT commands are accessible even if you have a custom firmware. You can also disable it if you need to.
