General uC driver that provides API to handle Quectel modems and choosing networks?

andras.szabo · August 29, 2019, 11:25am

Hello there,

is there anyone who can recommend any driver source code that we can use or buy to simplify modem driver development on our side? Our main requirements is that it has to be able to be integrated into threaded c/c++ source code. Big bonus if it is extensible or handles choosing GSM networks out of the box.

Thanks
Andras
