turn on or off RTC1 in nrf51822

[ALi]

I want to turn off BLE-peripheral Advertising for 8 hours but I want to use another timer with period of 50ms to scan GPIO , when I change prescale of

APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);

when I use a value more than 350 I think it doesn't work and I don't know how to test that in debug mode because it loops in main() function.

we don't have any function for stop BLE advertising to go in low power mode and after some hours we start that for 5 or 6 minutes to send data?

smells like something to do with PRESCALER value. What prescaler value are you using? do you understand how it works? please go through this thread to understand how to change it if you want to wait for longer time.
