3G and 4G modem for Raspberry PI

Fri Apr 05, 2019 12:18 pm

Hi all,

We are currently stuck on an important issue regarding making our RPI send data through a 3G and 4G modem. We are using a Huawei E3372, but we can not get it to work.

We would like to have a permanent solution that can be used when scaling up our production. If there is a modem as a plug-n-play solution, then that would be preferable.

Really need your help on this!

Best regards,

just to give you a one more idea, I choose Sixfab guys hat & modem products. I got a Quectel EC25 mPcie module and relative hat from them. In just 10min I got it working fine with QMI (Qualcomm modem interface) api. On their site there are some tutorial how to do step by step, and it worked flawless.
Then I bought a 4g SIM from (10 years,10 Euros) and now I'm working with .NET Core 2.2 webapi and I am superhappy.

QMI (better for 4G, NB-Iot): ... shield-v2/
