Direct modem access through USB on TRB160

Networking Solutions Question
1

I have a TRB160 router that I wanted to use together with a Linux fiber/ethernet router. However, the Bridge mode on TRB160 is very clunky and partly broken (see TRB160 IPv6 not routed to internet from ethernet ). So I would like to just use only the modem part and connect it directly to the Linux router through USB. I see that the EG060K module supports QMI/MBIM protocols and USB master and slave modes. So it would be great if I could use some kind of tricks or custom firmware that expose the modem protocols through the USB-C interface. All the other features of TRB160 are not really interesting to me. That would allow me to plug it into whatever I need and manage the modem through ModemManager.

Are there any available options like this?

Greetings,

Apologies for the delayed response.

This functionality is not natively supported, as the USB port operates as a virtual network interface. Because of this, there are no serial utilities that can be configured to provide direct access to the modem.

I will confirm with our Research and Development department whether this is a hardware limitation or a software related one. If it turns out to be software related, it may be possible to achieve the functionality using the SDK. However, developing and troubleshooting a custom implementation would fall outside the scope of our technical support.

I will get back to you with the answer from R&D.

Best Regards,
Justinas
