No network interface to work with on nrf9160

dpape

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

    Hi Daan, 

    Sorry for the late reply. 

    Happy to hear that you've managed to connect to a network(although briefly) and verified that the software works as it should. Yes, we need to check if this is a production error on your board or if its a network issue in Belgium and the Netherlands. I will contact our RSM in the Netherlands and ask him to test some nRF91 DKs to check the latter, if these work OK, then there must be an issue with your board and we will replace it. Does this sound OK?

    Hi Michel, 

    we're will investigate if there is an issue with the supplied iBasis SIMs. I will keep you posted.

    Best regards

    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).
