Known working miniPCIe cellular modem with SIM CARD

[llap]

Hi,

can anyone recommend any known working with resin os modems UMTS or LTE on miniPCIe (not USB) with SIM CARD slot?

My Quactel UC20G - have some connectivity issues with 2.7.5 so I would like to change it.

Kind regards,
LL

Hi @llap, the known tested modem list is in the docs https://docs.resin.io/deployment/network/2.0.0/#known-tested-modems- and in general modems from the ModemManager supported list should be working too https://www.freedesktop.org/wiki/Software/ModemManager/SupportedDevices/ I know that we were testing some mini-PCIe modems (@shaunmulligan probably knows the exact versions)

What sort of connectivity issues you experience with 2.7.5? Did you have any issues with the same modem on different resinOS version?

Looking at the resinOS 2.7.6 changelog, there is a new ModemManager version included in there, so maybe that might improve things for you…

Hey @imrehg,

the issue is as follows:

Quectel uc20g connection issues with Resin 2.0.9

Hi, I have this problem while using modem Quactel UC20G. It works when I run on resin host mmcli --scan-modems. But when docker image starts it disconnects and never connects again. Below is complete system log. When I use the same setup with ZTE MF823 modem it works fine. I have commented out udev trigger in my entry.sh file. I have the following section in connection (with infinite retries) but that does not help with Quactel. [connection] id=orangecellular type=gsm autoconnect=true autocon…

This did not work for 2.7.5. There is no known workaround at the moment. I know @shaunmulligan has done some work, and I dont know the result.

Quactel UC20G - not connecting - Resin 2.7.5

@lapacz, It doesn’t seem to be the case for all modems. I have v2.7.5 with 3 different Huawei modems and 1 Sierra Wirelss modem. It looks to maybe only be linked to the Quectel modems.

Yes, I have seen the links. However I am having hard time finding modems with sim card slot already built in into it and being available on EU market. Thought maybe someone would recommend any. Huawei or any other easily available.

Most of modems I find without sim card slot, and I dont like the idea of adding sim card adapter. Would rather have out of the box solution.

The 2.7.6 is not yet available for intel-nuc?

2.7.6 has not been released generally, but coming soon.

As for the modem selection, I think most modems these days use the external SIM card slot, unfortunately. There has to be some that fits your specifications as well, though. A quick online search turned up Advantech EWM-C109F601E for example, which is mini-PCIe, uses the uBlox lisa-u200 chip that we’ve tested, has onboard SIM card, and should cover Europe as well. This note is not an endorsement of the hardware, however, and we have not tested it to work. Just an example of a candidate.

Regarding your use case, you are trying to add cellular networking to Intel NUC devices?
