WP76xx Date and Time not updated

Legato Application Framework
1

Hello,

I’m developing an application using WP7607-1 module and have a few doubts with the Date and Time.

According to what I’ve read about the time update, the Time Daemon should update the time automatically when a network is successfully reached (Doc).

However, I’ve never seen the time being updated automatically. If I don’t manually update it, it would stay in 1980.

I understand WP76xx doesn’t include an RTC which prevents the time to be kept while not powered but I don’t understand why the time isn’t updated upon network connection.

The legato package I’m developing with is the following: Legato for WP76 R10.1 (18.6.3.wp76xx-docker-201810311826) for Windows

If it’s normal time doesn’t get updated I will add a time update handler in charge of manually retrieving and updating but I feel like I’m missing something and I might rewrite code that is already handled by the framework.

Thanks for your help,
Best regards,

Not sure if “ntpd -q -p pool.ntp.org” can help you to update the clock after data establishment.

In my side, the module clock will be automatically updated:

Hi jyijyi,

Thanks for your answer.

I’ve synchronised my module with airvantage platform and now it seems to update the time at each heartbeat.

Thanks for your help,
