RE: Question about bsp event handler

Hi Iyrics,

bsp_event_handler is the function for handling events from the BSP BLE Button Module.

bsp_button_event_handler is the function for handling button events. If you look at the function bsp_button_event_handler() in bsp.c, this is actually the app_button callback.

[quote user=""] is the app_timer created by 'app_button_init' continuously recognizing the press status of the button?[/quote]

yes. app_button_init() in bsp.c uses the value calculated by APP_TIMER_TICKS to calculate the delay from a GPIOTE event until a button is reported as pushed (detection_delay).
