nRF9160 as USB modem

Hi,

Recently I have been working on nrf9160 and wanted it to work as a modem for a linux computer for example raspberry pi. The aim here is that I connect the nrf9160 to the USB port of the rpi and the raspbian detects it as a usb modem. 

I tried the Serial LTE modem example and it uses AT command based TCP/ UDP sockets. My intend here is to use nrf9160 as a nbiot dongle (usb or serial). Is there any way it is possible?

Thanks in advance

  • What you're describing is possible but you will have to make your own Linux driver for this.

    You will also need to write your own nRF9160 application if you don't want to use Serial LTE Modem. 

    The nRF9160 does not have support for USB, but you could use an external USB or USB <-> UART chip to get around this.

    Additionally, due to the bandwidth of NB-IoT and LTE-M, your example of loading basic HTML page in a browser will take a long time. 

    Best regards,

    Heidi
