AT command for getting time

[xiao0528]

Hi, 

I am using nrf9160DK and ibasis card to test LTE-M signal. I can connect the network using LTE Link monitor as the following figure. But I can't use AT+CCLK? to get the time. What is the problem? I am using the latest firmware and v1.5.0 ncs. I use this sample in ncs\v1.5.0\nrf\samples\nrf9160\at_client.

Hi,

As explained in the documentation for the +CCLK command, not all networks provide the time.

That is probably why the command fails.

Best regards,

Didrik

You mean I need to change another sim card? Or change a place to try other network provider?

It might be enough to just change SIM card. But, I would expect that you have to change network entirely (which again might require a different SIM).

Another option would be to use NTP to get the time from the internet.
