Let the nrf51822 wake up after 3 hours

[Francesca]

Hi, I beginning now to program nrf51822. I would like to let the nrf51822 wake up after 3 hours by using a software timer interrupt. Should I use power_manage()? Before each power_manage() call, I stop all timer running. Current consumption is always more that 10 uA so the uC seems to wake up immediately after power_manage() call. How can I let the uC wake up ONLY through a 3_hours_timer_handler call? I'm using softdevice s130. Thanks!

The immediately wake-up after power_manage() means that a interrupt/event is triggered. power_manage() is only a function that will make CPU to go to sleep and wait for events. Check the power settings of the peripherals that you are using in your application.
