Button long press strange behaviour(SDK12.3)

[mm81]

main.cHi,

I have implemented button long press with APP_BUTTON library with APP timer (a 5 seconds timer). Normally the detection works fine.

But I found that if the system has been left running for a period of time, it will immediate trigger the long press handler when i press the button (instead of after 5 seconds).

The pin in question is P0 (update. tested on another button have similar effect)

Any idea on this??

Thanks.

Hello,

err_code = app_timer_create(&button_power_5sec_timer_id, APP_TIMER_MODE_SINGLE_SHOT, button_5sec_timer_handler);

• Is your button_power_5sec_timer_id variable a global / static variable? It has to be.

• Did you configured the timer as a APP_TIMER_MODE_SINGLE_SHOT / APP_TIMER_MODE_REPEATED timer?

• Can you show me the code related to the APP_BUTTON_RELEASE part and the timer handler part?

I think your code when pressing the button doesn't seem to be a problem.

I cannot tell big issues without those parts.
