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 Hakon,

Thanks for your reply.

Håkon Alseth said:

Is this due to the network connectivity, or the connection to the server?

I think it is due to the network NAT timeout. Can that be the case? what do you think?

Håkon Alseth said:

Is the communication still unstable with other samples, like mqtt_simple?

Yes, the same think with udp_sample and coap_sample.

Best regards,

Cedric

[Håkon Alseth]

Hi Cedric,

 

both coap and the udp sample are UDP based, while the latter one only sends data.

Could you try a TCP based sample to see if it has specific issues? A log would be great to see as well.

 

Kind regards,

Håkon

what does that means for me?

Hi,

 

It looks to connect and run as expected, LTE network wise, but you're getting an error on the message size:

2021-11-09T13:24:50.639Z DEBUG modem << [00:01:12.078,552] [1;31m<err> mqtt_simple: publish_get_payload failed: -122[0m

This translates to:

https://github.com/eblot/newlib/blob/master/newlib/libc/include/sys/errno.h#L153

 

This is because the default buffer size is 128, which can be adjusted using config "CONFIG_MQTT_PAYLOAD_BUFFER_SIZE"

 

Kind regards,

Håkon
