Hi
I was working with BG96. There was a requirement to read network time. I used AT commands as:
AT+CTZU =1
AT+CCLK?
It works fine in initial case when module was in India. But when Module location changed to other country ,it is unable to read the network time. Is there any dependency for these AT commands like service provider or location?
Network time synch is highly dependent on the Service provider . If service provider is not broadcasting then module cant get it .
Other option is using QNTP command to get Network time from network server .
Please refer TCP application note for using of above command .
