Huawei USB Modem and Connman

Hi @stefan_e.tx ,

Thanks for all of the suggestions.

CONFIG_USB_NET_HUAWEI_CDC_NCM and CONFIG_USB_NET_CDC_MBIM were not enabled in my build.
I enabled both and re-flashed the kernel and modules.

I see no change. PPP still works; however, Ofono’s test scripts do not find the modem.


Hi @mikec

Unfortunately our team runs out of ideas. If you really need to use this modem with ofono, I have to redirect you to one of our partners who could do a proper integration.

I’m sorry we can’t solve your problem.


hi @mikec

Is your issue solved? If yes, can you share the solution please? If not, then you might have a look here.

Best regards,

Hi @jaski.tx, we never did get the issue resolved, and in the end we switched to a different modem manufacturer and used ppp dialing. Thanks for the link to the other post. Will have a look to see if that fits our needs.


Ok, we will be happy to get your feedback.

Hi @Ayoub

Welcome to the Toradex Community!

Could you ask a new Question and provide all the information (version of hardware and software= about your Toradex module?

Thanks and best regards,
