No NITZ time update callback QUEC_NW_NITZ_TIME_UPDATE_IND after successful network registration

Hello Quectel Team,

We are using EC200U and have registered the network callback using ql_nw_register_cb().

Network registration completes successfully (CREG/CGREG Home, LTE attached, operator info and cell info indications are received), but QUEC_NW_NITZ_TIME_UPDATE_IND is never triggered, even after waiting more than 10 seconds.
Other network indications are received correctly.

How can I successfully get NITZ time? which other API can I use to get time from network ?

Thank you.

Use the AT command: AT+CTZU=1

Hello,

Thank you for the suggestion.

We are using EC200U in controller mode (application runs on the module itself) and do not use an external AT command interface. All network handling is done through the Quectel C SDK APIs
What is the maximum recommended timeout to wait for NITZ after network registration.
How an I successfully get NITZ time using API’s from SDK(LTE01R03A08_C_SDK_U)
