I'm currently working with sara-u201.
When I first initialized sara-u201, I used AT+CCLK? to get the current time of the module. It was 04/01/01 00:00:00.
Then I configured my SIM Card to connect to a server and read the current time again using AT+CCLK?. the time was updated to the real time compared to the internet.
But I didn't use any AT commands to set the time for sara-u201. So, did the time automatically updated the time when my SIM Card connected to 3G network?
Thank a lot.
