How to Wake up Device from Sleep using RTC

[Mr.NCK]

Hi,

I have using nrf52832. I have done the device sleep by using RTC. But, it's not wake up from sleep. How Can I wake up the device from sleep?

I need help regarding this

Thank you,

Hi,

You should see the RTC example in the SDK, it implements IDLE ON Sleep and wakes up when a new RTC event is generated.

 I can take a look at your code if you share it.

Hi,

It's very difficult for an external to review your code as it's not organized. My guess is your application is asserting somewhere the second time it goes to sleep. Try to debug your application and see if it hits the error handler at some point.

Hi Jarod

https://devzone.nordicsemi.com/f/nordic-q-a/44846/nrf52832-system-on-sleep-from-rtc

This is what I am trying to do. But, I need to do Sleep for a specific time. That time can be configured at any time

please help me with this

Thank you

Hi again, 

Could you use the debugger and verify that the example enters sleep the second time? If not, then it's probably hitting an error handler.

Yes, your points are correct because of my calendar module RTC. I can't able to initialize the Sleep time RTC instance. That's why it's creating the issues 

[Jared]

So before you go to sleep a second time you try to re-initialize the module?
