How to set APN in SDK v1.9.1 "https_client" sample project on nrf9160.

OYAMA YUKIO

Hi all,

In my SIM, I need to set the APN name, username and password. They are not written to the SIM, so I need to set them.

With the at_client App provided by Nordic, I have already been able to connect to LTE using AT commands.

I think I can connect to LTE if I can set it correctly in the code, but I don't know where to set the APN information in sample project.

1,

I referred to the following thread.

devzone.nordicsemi.com/.../343313

And I added the following to the prj.conf file, but it failed with LTE connect.

# PDN library

CONFIG_PDN=y

CONFIG_PDN_DEFAULTS_OVERRIDE=y

CONFIG_PDN_SYS_INIT=y

CONFIG_PDN_DEFAULT_FAM_IPV4V6=y

CONFIG_PDN_DEFAULT_APN=”APN name”

CONFIG_PDN_DEFAULT_USERNAME=”user name”

CONFIG_PDN_DEFAULT_PASSWORD=”password”

Am I missing something? Or do I need additional Including within the main?

2,(Another way)

I referred to the thread below and thought I could use AT commands in my code.

https://devzone.nordicsemi.com/f/nordic-q-a/70961/set-apn

Do I need to write additional code to use AT commands?

Seems like I need to include <modem/at_cmd.h>.  but can't find <modem/at_cmd.h> .

Is my guess correct that there are two different approaches to setting the APN?

Which is the best way? Is there another way?

My HW : nRF9160DK

MFW : v1.3.1

SDK : v1.9.1

Best regards,

    Hello Øyvind-sann,

    I was able to connect to LTE using #1.

    I mistakenly used some symbolic-character double-byte characters in the string. This is the reason why #1 was not possible. Japanese letter is a double-byte character, but symbolic-character are often mistaken for single-byte characters. Sorry.

    In #2, an error occurs in the "at_cmd_write()" command. Is #2 method impossible?

    Is there a reference manual that describes the information that can be set in the prj.conf file? I couldn't find it.

    The AT command is described in detail. So I think it more effective to use AT commands inline.


    I'm already connected to the LTE network, can the SIM information help me with my questions?

    Thank you.
