nrf9160 modem get stuck in LTE seaching

[ced27]

Hello,

for some days now, my modem is unable to connect to the network, it gets stuck in searching and i don't know why?. I am using an eSIM card from iBasis and i am trying to connect over LTE-M or NB-Iot to the californium server, but it just gets stuck.

Note: The modem hasn't been doing this in the past, it just started getting stuck some days ago until now

Can someone please help me .

Hi,

 

Could you try to connect with at_client firmware, in combination with LTE Link Monitor (from nRF Connect for Desktop) and issue these commands?

AT+CEREG=5
AT+CFUN=1
AT+CFUN?

 

Let it run for 10 minutes and post the log here.

 

Kind regards,

Håkon

Hi Cedric,

 

It shows that you're connected (roaming state) after approx. 18 minutes, but I was hoping to get more information out here.

Could you run this in LTE Link Monitor? This applies, by default, a series of AT commands when you query AT+CFUN?.

 

Kind regards,

Håkon

I issued all the commands directly in LTE Link Monitor after i ran at_client. Should i run it a little longer?

But as usual before connecting it takes much time

[Håkon Alseth]

My apologies.

Could you ensure that automatic requests is checked in the lower right corner of the application?

 

Kind regards,

Håkon
