How to set nrf board time in sync with mobile using ble ?

[rkc]

I have been working on receiving data from sensor using nrf52832 and I have been successful in getting the data and printing the same in the app. I have also been succesful in printing the local time running on the board using RTC. But, I am not able to sync the local time with current time running in the app. Please, help me with the function, macro or the example code to link the app time on to the board. 

Thank you

I have used ble cts code which is using rtc2 and I am already using ble uart for transferring data to phone with same rtc2. I am not able to use the same rtc for two different programs. Please, tell me if code chosen is correct or should I go with some other method to achieve the output.

What are you using RTC2 for for BLE UART? Can you not use the app_timer for this, which is running on RTC1?

I am not able to sync the local time with current time running in the app.

Which app are you using? Does it support the Current Time service? Have you tested the method described in the Testing section in the Current Time Application?
