No network interface to work with on nrf9160

Hello,

I followed the getting started guide but the kit can't connect. I'm getting this error:

net_if.net_if_init: There is no network interface to work with!

Is this a known bug, how can i fix it? Or is there a hardware issue?

Kind regards,

Daan Pape

  • Same issue in Croatia. Tried 3 different sim cards (iBasis, T-Mobile & Tele2) and no success. LTE link monitor shows all red statuses (UART, modem, ...). I’m connecting DK on macbook pro over usb to usb-c adapter. Updated firmware and uploaded at_client sample code but after that no response from DK on AT commands.

  • Ok i realized that i'm not updating modem firmware, getting timeout error.

    And LTE link monitor app is definetly not working ok. When i connect DK to mac and start LTE monitor app, in device selection drop down i have 3 ports. All statuses are red.

    If i switch power off and on, LTE link monitor app show only one device and i can't connect to that one device.

    This behavior is present from first time when i started DK out of the box and after getting "No network interface to work with" error and messing with firmware and at_client i don't get any response from modem any more.

  • I am experiencing pretty much the same thing. I am located in New Brunswick, Canada. Out of the box, the asset tracker demo did not work with the iBasis SIM. I tried with a Twilio SIM and it did not work either. I successfully installed the new modem firmware. Then I followed the "get started tutorial" and flashed the board with the "asset tracker" project (which I built using SES): still not working. Finally, I tried the "at_client" project (again built using SES), and all badges are red (i.e. UART, Modem, UICC, LTE; and PDN is gray) in nRF Connect for Desktop (LTE Link Monitor app).

  • With the "at_client" project I had to do the following:

    - In LTE Link Monitor make sure you have closed the device.
    - Flip the power switch on the DK ON->OFF->ON
    - In LTE Link Monitor select the device
    - Hit the RESET button on the DK
    - Send 'AT+CFUN?' twice. After the first command I just get '+CFUN: 4' and 'AT+CFUN=1' seems to be sent automatically. The second time I send the command a lot of other commands are also sent. For me at least UART, MODEM and UICC turns green and LTE are flashing yellow. Unfortunately it doesn't connect.
