Asset tracker v2 doesn't connect

[Chris]

Hello,

I have the nrf9160 DK version nRF9160 SICA B0A. I have upgraded it to the latest modem firmware version 1.3.2.

I put my own SIM card and added in prj.conf the following lines:

CONFIG_PDN=y
CONFIG_PDN_SYS_INIT=y
CONFIG_PDN_DEFAULTS_OVERRIDE=y
CONFIG_PDN_DEFAULT_APN="internet"

Running the example it throws me few errors that Im not sure how to fix.

I know for sure that my APN is connect.

Below are the logs

If I convert all errors codes to text I'll get the following

 Link data not obtained: 5 -22 --> MODEM_INFO_OPERATOR : Invalid argument

 Link data not obtained: 8 -22 --> MODEM_INFO_CELLID : Invalid argument

 Link data not obtained: 3 -22 --> MODEM_INFO_AREA_CODE : Invalid argument

 Link data not obtained: 20 -5 --> MODEM_INFO_DATE_TIME : I/O error

 Network data not obtained: -71 --> Protocol error

 modem_info_params_get, error: -11 --> No more processes

It seems to me that there is compatiblity issues between my SiP revision and the fw 1.3.2 ?

Please advice how to further investigate this issue

Hello,

It seems to me that there is compatiblity issues between my SiP revision and the fw 1.3.2 ?

I think this depends on what SIM/operator you are using.

Looks like you are getting disconnected from the network for some reason. Maybe you can capture modem trace to investigate this.

Hello Hakon,

The traces are attached here /cfs-file/__key/communityserver-discussions-components-files/4/modem_5F00_trace_5F00_wireshark.pcapng

The only fail I see is At+CCLK? that gets ERROR as answer. Based on the AT command documentation the test command is not supported

Can you please advice ?

[Chris]

I was able to fix my issue by disabling these config in prjconfig

CONFIG_PDN=y
CONFIG_PDN_SYS_INIT=y
