[Zita25]

Hi.

I'm pretty new with SEGGER Embedded Studio and with nRF9160 dk.

I would to receive time with NTP serveur but I'm lost.

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.

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

I hope than someone can help

Sorry for my bad English

Hi,

 

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.

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

 

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

 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?

 

Sorry for my bad English

No worries, it was perfectly understandable!

 

Kind regards,

Ok thanks 

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.

I hope you can help me again

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,

Hi,

Yes i had the "CONFIG_SNTP=y" in my prj.conf file,and re-imported the SLM project in segger embedded studio.

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,

Håkon
