Hi Didrik,

This solved the problem. Thank you

Unfortunately, that didn't help as much as I had hoped.

Which SDK version are you using?

If you are not using NCS v2.6.0, could you try that?

I assume you are using the same power supply and SIM card when you use the basic networking example and the at_client?

Also, can you try to set CONFIG_LTE_NETWORK_MODE_NBIOT=y?

Hi,

Can you enable some more logging, so that we can get more details about what is happening?

CONFIG_LOG=y

CONFIG_LTE_LINK_CONTROL_LOG_LEVEL_DBG=y

Best regards,

Didrik
