Programming with RUI, without AT commands?

Hi, it’s possible to write a program to do something (like read a gpio and send state across lorawan every minute?) without use at commands?

It is. You can check the RAK Git for your device.

Thanks for your answer!; I check it, but if i want to send data periodically, i’ve to write by serial AT+interval… to make the send. I want something like this: turn on module, read data from gpio, send data, go to sleep; i don’t wanna use the serial to write the at command; i don´t see any example like that; regards

There are no examples for this case right now. Soon will be added more. You can try to build your solution based on RUI, or wait for example code for something similar.
