Support for SIMCom SIM7070G-based modems please


Recommended Posts

I would love to see support for modems based on the SIM7070G chip. Along with Quectel’s BG96, SIMCom’s 70x0 and 7x00 families seem to be the leading choice when it comes to IoT-related applications with LTE-M and NB-IoT.

 

Shenzhen-based AND Technology manufactures and offers two very affordable modems (< USD 25) using the SIM7070G:

  • BK-SIM7070G (a break-out board with serial interface) -> AliExpress
  • DG-SIM7070G (a USB stick/dongle) -> AliExpress

 

Sidenote: Waveshare has a Raspberry Pi HAT based on the very same chip –> SIM7070G Cat-M/NB-IoT/GPRS HAT

 

SIMCom as chip provider offers excellent documentation on their website. I've put all files list below in a ZIP archive which can be downloaded here.

 

I've also opened a github issue on this, in case you want to discuss there.

Armbian is a community driven open source project. Do you like to contribute your code?

Take a look at ModemManager along with libqmi/libmbim... should support this out of the box with the packages installed.

 

It's a Qualcomm MDM9205 solution, similar to QuecTel and others.
