Hi, I am currently meeting this issue. I have followed the supplied guide and configured the kernel as well as tried this using modules.
The AT Commands work fine with obtaining HTTP requests, though I will need to make this work with QWWAN.
The module being used is:
Quectel
EG21
Revision: EG21GGBR07A09M1G
Log from Qconnect is below.
