Hi Zita,

Have you added the date_time.c to your serial_lte_modem/src catalog? If yes, please remove it from this directory, as it is automatically added to your project by setting the prj.conf::CONFIG_DATE_TIME=y.

Kind regards,

Hi,

[quote user="elsal25"]

It does not compile perfectly because i have twice the library in my tree and i have trouble understanding what i did or did not to get there.

It seems that you only have included the library once, so that should be OK.

Did you add the "CONFIG_SNTP=y" to your prj.conf file, and re-imported the SLM project in segger embedded studio?

If yes, could you please post the whole build log?

Kind regards,

Håkon

Hi,

[quote user=""]I don't know what to use. if it is better to use this sample : https://github.com/Rallare/fw-nrfconnect-nrf/blob/nrf9160_samples/samples/nrf9160/ntp/src/main.c or the date_time librairy.[/quote]

This example was written at a time when sntp wasn't working with nrf9160, so please use sntp now.

[quote user=""]I tried to import the library in the application serial_lte_modem and modify my configuration files but when i buid i have this error : "undefined reference to 'sntp_init'" in the date_time.c[/quote]

Try opening your project configuration file "prj.conf" and adding CONFIG_SNTP=y, then reloading your project (re-import in SES).

Are you able to build successfully now?

[quote user=""]Sorry for my bad English[/quote]

No worries, it was perfectly understandable!

Kind regards,
