NRF9161 DK communication to NRF Cloud

[robsrick]

Hi,

My device with the IBASIS sim set up per the getting started guide is not connecting to NRF Cloud. I've analyzed the wireshark trace and it looks like a conection is established and a DNS request goes out for NRF Cloud but no response is received and a detach request occurs very quickly. I also sometimes see that attach fails for "No Suitable Cells In tracking area" error but it isn't more specific as to what this means? 

Could i have some help analyzing the wireshark trace to determine what's causing my issue?

Hi,

The device attaches to the UK O2 network, but is kicked out as soon as it tries to send an IP packet.

This is because of a change in the O2 network, that has caused problems for a lot of roaming devices.

Please see this ticket for more information:  ESM Error Code 50: type ipv4 only allowed (NRF91 Asset Tracker)

Best regards,

Didrik

Thanks Didrik, any word from IBasis on this? a fix / alternative network? It seems I can't get any connection at all..

I haven't heard anything from iBasis, but you can try to contact them to hear if/when they plan to get a roaming agreement in place in the UK.

Other than that, you will have to find another SIM card provider with the coverage that you need.

Other than your local operators, you can try to look into Telefonica Spain, which still have access to the O2 network, along with other countries (though I don't know exactly which ones).
