My first post, I have to say that it is really good documented work what you guys are doing.
Back to the subject.
I am using a rak3172 evaluation board, with rak19010.
But there is a particular sensor(rak12039 PM dust sensor), that when connected and run rakwireless_github_example with Arduino IDE, AT commands will stop working. And I will have to repair firmware to get it back to work.
It happened twice already.
Is that small piece of code broken? or am I using the wrong example code? I might be doing something wrong.
