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 guys, 

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

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

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

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

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

f0corner: 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.

Hi bjorn-spockeli, no luck in manual connection. I tried with AT commands but always getting error.

I called and sent emails to t-mobile, only operator in Croatia who provide NB-IoT network and they told me that possible reason for no connection is that i don't have data plan for NB-IoT. Problem with this is that their data plan is being selled only to business users (companies) and they can't help me with that. Also they told me that all their sim cards work without problems and supports NB-IoT, which is contradictory with their previous answer.

I don't see any logic in what they talking to me. Ok, if i don't have data plan i should sucesfully connect but than i would not be able to send any data, that's ok. Also if iBasis sim card is trying to connect to same t-mobile network, in theory why roming should not work, iBasis have their own data plan and uses it, not theirs.

I purchased another sim card (4 cards tested so far in total) from them and i got same problems - modem found some network, try to connect but after mili second it seems like it disconnects. Signal bars fill up but after that goes blank.

Filip Skorup: The nRF9160 DKs are flashed with LTE-M modem firmware, but I see that you've updated the FW further down in the thread. Could you run the AT+CGRM command and post the output in a comment? This will print the modem firmware version. If you have the LTE-M firmware, then its no wonder that you're not able to connect to the NB-IOT network.
