Hi,

This issue is related to how the state machine in the app_button implementation works. It always assumes that the pin will be in idle state when the app button library is initialized. This post describes it very well and also suggests a workaround.

Hi, unfortunately still doesn't work. I implemented the buttons using app_button, but realized it's basically the same thing as what the BSP does, not sure the benefit of initializing everything app_button. More simple maybe?

Anyway, my problem is if I hold down a button upon startup, it doesn't detect the first release. Any thoughts?

Sounds good. Please let us know if that (wrong active state configuration) was the problem.

Hi, I have the same problem. Was this ever resolved? When I hold a button down upon wakeup, it doesn't detect the first release. Using nRF52832/nRF52 DK on SDKv16.0.0. S132 v.7.0.1. Using example ble_app_uart_c.

Do you use the button to wake up from system OFF?
