Of course you can!

As Jørgen Holmefjord said earlier, the e nrf5-calendar-example receives the time over HW UART - so there's no reason why you shouldn't do the same over BLE ...

It's all just about transferring data

ok i dont have that much time to do that!! can i set time using nrf tool box app via bluetooth,like if i send a year and put that in a variable using uartput function?? is that possible

CTS is the BLE Current Time Service

As the name suggests, its purpose is to expose the current time!

There is no support for automatic update of time over CTS in nRF Connect or nRF Toolbox, you will have to write your own application that gets the current time from the OS and writes this to the Bluetooth Service. The Current Time Service is native to iOS, meaning it may update automatically as you want.

The nrf5-calendar-example receives the time over HW UART, not over BLE. It can be used to keep track of time, but there is no support for synching the time in the example using BLE/CTS.

You will have to implement the synchronization between these two modules yourself.

There is a current thread on this:

https://devzone.nordicsemi.com/f/nordic-q-a/67421/how-to-set-nrf-board-time-in-sync-with-mobile-using-ble

suggest you follow that, rather than duplicating ...
