Huawei LTE Module ME909s-120 support

Hello,
i recently bought a PC-Engines APU4d and opted for a LTE miniPCI. i didn’t paied attention to the card type and i ended up with a Huawei ME909s-120.
with the rolling image from 17072020 when i boot it get’s detected as a usb Huawei mobile V7R11, but it don’t show up in the interfaces lists.
a show hardware usb report it as Huawei ME906s LTE M.2 Module.
Anyone have some info on how to get this card working?
are there in the kernel a option i can enable or compile?
i have not installed any sim card, i figure it should be recognized without.
Thanks

Hi @cnicules,

I know it maybe too late but there is a list of “known to work” modules at https://docs.vyos.io/en/latest/interfaces/wirelessmodem.html#supported-modules. I for myself use also an APU4C4 board and did all the WWAN development on the rolling release there. From my knowledge there might be “special” cards which require some special udev treatment (Sierra MC7710 for isntance).

If you retrieve the module id via show system usb serial the Model you receive is the one branded into the WWAN EEPROM.

but it don’t show up in the interfaces lists.

It will only show up in the list once you properly configure it using this guide: https://docs.vyos.io/en/latest/interfaces/wirelessmodem.html

If this still does not work we can chat on https://slack.vyos.io and get your card working/add support for it. But you should get yourself a SIM card first so we can properly test it.

Hi,
trying to configure and i get errors at the device name.
if i don’t add a device and only an apn i get a commit fail.
if i want to add a device i don’t know the name, tryed different ttyUSB, usb001, all fail.
There is nothing at the output of the “show system usb serial”

The commands have recently changed to better fit into the existing layout. Please try: show hardware usb serial. Or simply send me a direct message via Slack.
