Hi Sebastian,

Glad to hear that it started working!

You can either hard-code it in the application (runtime set at every boot), or store it once using at_client (before modem is active) by issuing new APN, then "AT+CFUN=0" to store it.

Kind regards,

Håkon

Hi,

Yes, other samples get a connection on my kit (for example at_client). I checked the systemmode too and it returned the same value as you suggested it (%XSYSTEMMODE: 0,1,0,0).

Is there something else I can try?

EDIT:

> I may found the reason why I can send a package but the server does not receive it. The kit chooses a private apn of my provider.

> I do have a public apn but how and when should I set it in the udp_with_psm sample?

EDIT:

> Now I am sure that the wrong apn caused the issue. Why I know that: If my public apn is set manually (+CGDCONT=...) via the LTE Link Monitor right after the start of zephyr booting, the kit registers with the correct apn and I can receive the sent data in our server. *happy* ;)

Hi,

Does any other sample get a connection on your kit?

Have you tried using the at_client to see if that works (post a log if you have issues)? Note that you have to change the systemmode (AT%XSYSTEMMODE=0,1,0,0) before enabling the modem to enable NB1.

Kind regards,

Håkon

The unmodified sample does not seem to work (I assume the network type NB is not selected).

The only difference between the unmodified and mine is the added line in the prj.conf: CONFIG_LTE_NETWORK_MODE_NBIOT=y and a different host and port in the main.c.

The file below shows the output where I only changed the prj.conf:devzone.nordicsemi.com/.../4101.test1.txt

This file is with the modified prj.conf, host and port:

devzone.nordicsemi.com/.../test2.txt

Hi,

Does the unmodified sample work?

What is the output from your current modified version?

Kind regards,

Håkon
