regarding gpio functionality

[vjgarg]

hi,

We are using nordic nRF52832 in our project as per our requirement we have to implement sleep and wake up mode with the help of button interrupt. our use case is that after long press of 3 seconds device starts advertising(exit sleep mode). and again after long press of 3 sec device goes to sleep mode(ideal state). Since we are having only one GPIO which will perform many cases such as on single tap session terminate,long press for 3 sec device goes to sleep and again if device is again pressed for 3 sec device will come out from sleep mode and when device is tapped 2 times it will terminate connection. we are not able to understand how can we implement these cases. currently even long press feature is not working. please help us to solve this issue.

Hi,

You can implement what you want by detecting the button push and starting a timer (typically using the app_timer library) to measure the time until the button is released. This is implemented in the BSP that is used in the SDK examples, but it may be unnecessarily complex. Alternatively you could implement it yourself, for example by combining the Button handling library to do debouncing and the app_timer do measure the duration of the button press.
