Hey @prash, we’ll be adding more info to the documentation, but in this github issue you can find a list of currently tested 3G modems:
There’s also Soracom’s example that we’ve used at the London Hackathon very well recently, i think with Huawei MS2131 dongle. Here’s a demo project, and more info will come shortly:
Let us know if you try any of these and what’s your experience!
@prash in general most of the dongles listed in ModemManager’s device support should work out of the box. The main problem I have seen with some modems is that they aren’t autodetected by usb_modeswitch, which means resinOS doesn’t know how to switch the modem from storage media mode to modem mode.
Out of interest what kind of requirements does your project have on the modem?
