I also don’t know why alfie recommends the hilink ones, since the stick ones expose AT commands just like the Quectel internal modules GL uses and use yeah NCM for the connection itself. You get more options in the UI with cell info etc, while the hilink just says tethered and ip. Hilink also has it’s own NAT, so you are fighting with that to open ports as well if needed.

If you want to read about flashing hilink to stick for the E3372H see this:

Try the top section “did not work for me” first, as there seems to be many different versions with different options for flashing, progressively harder to do. I say harder because for some people opening the stick and bridging the test point to ground would be considered no fly zone, while others would love to even desolder the entire MCU :rofl:
