RTC stops on BLE disconnect

[Vijayalakshmi]

Hi, I have a application that receives the Epoch time from the Android Application and increments every second. and needs to store and increment the Epoch Time value even after BLE disconnect. But unfortunately the Timer stops on ble_disconnect.

Can anyone explain how to implement the Timer..

Thank you

That's what the RTC is for. You can send the initial time from the phone at start, but afterwards you can just start a repeating timer with 1 second interval and do timekeeping there. You can take a look at the simple_timer example in the SDK.

Which RTC do you use, RTC 1? (RTC 0 is blocked by the softdevice when the softdevice is enabled (System on Chip resource requirements --> Hardware peripherals)
