I have tried lots of youtubes, tech blogs, and even chatgpt and i cannot get the thing to work with openwrt. I did follow the Getting Started With Clipper HAT Mini post on a basic RPI and it worked fine on there so i know the card and the sim car work, But i want to use it with OpenWRT which i would have thought most people would use
You will need to implement the UART-based AT-command communication yourself. Probably there is a lot of boilerplate code available, since OpenWRT also support many old UMTS-sticks that also use UART and AT-commands for the communication.
