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

  • Hi guys, 

    first I just want to say thanks for all the feedback with regards to the LTE Link Monitor, iBasis SIMs and coverage issues. 

    and : iBasis has confirmed that they have some issues with LTE-M in the NL. They are sorting this out now. 

    : Great, happy to hear that you've been able to connect to AT&T!

    : Did you have any luck manually connecting to one of the networks in your area?

    : nRF9120 is the SoC used inside the nRF9160 SiP. Are you still having issues connecting with the iBasis SIM in Sweden?

    : You could try contacting your local Nordic RSM and ask if they have any information regarding the LTE-M Coverage from Bell in Canada or if they have tried using a Telus SIM. 

  • I know this is an old thread, but I still wanted to share new developments I had with the DK.

    So, first, it is worth mentioning that I had not have the chance to retry connecting to a network using my nRF9160 DK since my last comment in this thread; which was roughly five months ago.

    That being said, two weeks ago, I updated the modem's firmware on my DK to the latest version (i.e. mfwnrf916007029alpha) and gave it another shot. It is now working. I cannot tell, however, whether it was the network that wasn’t available at my location a few months ago or whether it was an issue with the previous firmware versions.

    I tried with two SIMs (and it worked with both): the iBasis SIM that came with the DK, and a Twilio SIM. I am located in Northwestern New Brunswick (in Canada). I see that the iBasic SIM connects through Telus’s network, while the Twilio SIM connects through Bell’s network.

  • Just a little correction... Above (in my last comment) I'm saying that I couldn't tell whether the absence of a network or malfunctioning firmware was my problem. However, I failed to mention that, two weeks ago, I first retried connecting without updating my DK and it didn't work. Only after updating the firmware to the latest version did it start working. So maybe it was an issue with the firmware after all, especially since both Telus and Bell have been advertising nationwide LTE-M coverage for at least the last six months.

  • Hi ........... thanks for the info. I'm based in the UK and the issues regarding coverage are still resulting in poor overall service in my part of the country (Wales). I understand that the East of the UK has some coverage. I've tried the kit in the South of France with some colleagues and they got it to work but the concensus is that things are still a "work in progress" as far as the kit is concerned. We have contemplated creating our own platfrom but testing in our part of the UK is a no-go presently. It's really a shame as the device has great promise but unless things get resolved fairly quickly with it then I fear the competition from the Far East will steal market share. We have had some good experiences with other modems in our testing with partners in Malaysia.        If someone from Nordic wants to get in touch I think we could create something more usable for developers who are looking at the device from a metrology perspective.

  • : We're constantly improving the modem firmware for the nRF91 towards the production release, hence we always recommend using the latest firmware available here. Coverage is a bit more difficult to assist you with, but I would recommend that you talk to our RSM in the UK.  Our RSM should be able to give you more information on the status of the LTE networks in your area as well as the roll out plans. If you do not have our RSM's contact info, then send me a private message and I will provide it to you. 

    Best regards
