Wake up from sleep mode

[enkavak]

Hello,

       I want to use ble_app_uart example. I'm usign nRF52832 with nRF5_SDK v15. I need to put the MCU in sleep mode. I can do that. When the MCU awakes from sleep, I do not want to run the BLE stack directly. I will make some measurements and then if it is needed, I will run the BLE stack. 

      How can I do this ? any idea ?

Best Regards

Hi

If you configure an app_timer callback you will be woken up at regular intervals, so that you can make your measurements, do some calculations, or whatever else you need to do, independently of what the BLE stack is doing. 

The BLE stack will have it's own internal events that will wake up the CPU when the BLE stack needs it, but this is invisible to the application (until the BLE stack sends an event that you need to process). 

I don't know what you mean about only running the BLE stack when you need to. If the BLE stack is advertising, or in a BLE connection, it will need to run the MCU at regular intervals to keep the connection/advertising running. 

Best regards

Hi 

I can't find any question from you, what do you need help with?

Unless it's directly related to the old case I would suggest you open a new question about it, it makes it much easier to track. 

Best regards
