Button inturrpt works only once

[Yaniv Reibenbach]

Hi,

We have added support to button click in our design but the intruppt only works once at the first time it is pressed.

What am I missing here? why is the button_evt_handler working only for the first button push?

static void button_evt_handler(uint8_t pin_no, uint8_t button_action)

{

//todo something

}

static void button_init(void)
{
ret_code_t err_code;
const uint8_t buttons_cnt = 1;
static app_button_cfg_t buttons_cfgs =
{
.pin_no = BUTTON_1, 
.active_state = APP_BUTTON_ACTIVE_LOW,
.pull_cfg = NRF_GPIO_PIN_PULLUP,
.button_handler = button_evt_handler
};

err_code = app_button_init(&buttons_cfgs, buttons_cnt, APP_TIMER_TICKS(100));
APP_ERROR_CHECK(err_code);

err_code = app_button_enable();
APP_ERROR_CHECK(err_code);
}

int main(void){

....

button_init();

....

}

Hi , check this post devzone.nordicsemi.com/.../15775

The link is about button push or realese.

Im my case I care only about Push and the button_evt_handler is called only once in the first push and not working(no function call to button_evt_handler) in any of the follwoing push buttons 

Is there a command that needs to be registred after every usage of the button_evt_handler?

Try this example :SDK\examples\ble_peripheral\experimental_ble_app_blinky

and edit the function like below (static void button_event_handler(uint8_t pin_no, uint8_t button_action))

{
        uint32_t err_code;
  
    switch (pin_no)
    {
           	case LEDBUTTON_BUTTON_PIN:
                      switch (button_action)
                      {
                             case APP_BUTTON_PUSH:
                                  // Do your task
                             break;
                            case APP_BUTTON_RELEASE:
                                  // Do your task
                            break;
		  default:
                                break;
                       }
              break;
              default:
              APP_ERROR_HANDLER(pin_no);
              break;	
    }
}
