Hi 114r5,

I am glad to hear that you found the issue and solved it.

You should not change things in "app_timer.c" , that can cause unwanted behaviour as you saw yourself.

If you want to increase the queue size you do this in the "sdk_config.h" file.

Oh, I think I found the problem.

One day, in app_timer_init(), I changed m_op_queue.size = APP_TIMER_CONFIG_OP_QUEUE_SIZE+1 for m_op_queue.size = APP_TIMER_CONFIG_OP_QUEUE_SIZE+2. (sorry for that silly change, don't ask me why)

Now I turned back to its original state and seems to work well. How does it affect to the code? Why a change like this may cause that kind of problems?

No luck.

I tried doing the same action using the bsp functions as it is done in the bsp example and the result is the same. At the third push, the led fades fastly and the button responds no more. No error is fired.

void bsp_evt_handler(bsp_event_t evt)
{
	uint32_t err_code;
	if(evt == BSP_EVENT_KEY_0)
	{
		actual_state = BSP_INDICATE_BUTTON_PRESSED;
		err_code = bsp_indication_set(actual_state);
		APP_ERROR_CHECK(err_code);
	}
}

void leds_and_buttons_init(void)
{
	uint32_t err_code;
	err_code = bsp_init(BSP_INIT_LED | BSP_INIT_BUTTONS, bsp_evt_handler);
	APP_ERROR_CHECK(err_code);
}

static uint32_t bsp_led_indication(bsp_indication_t indicate)
{
    uint32_t err_code   = NRF_SUCCESS;
    uint32_t next_delay = 0;

    if (m_leds_clear)
    {
        m_leds_clear = false;
        leds_off();
    }

    switch (indicate)
    {
        case BSP_INDICATE_IDLE:
            leds_off();
            m_stable_state = indicate;
            break;
				
		case BSP_INDICATE_INIT:
				bsp_board_led_on(1);
				err_code = app_timer_start(m_leds_timer_id, APP_TIMER_TICKS(3500), NULL);
			break;
			
		case BSP_INDICATE_BUTTON_PRESSED:
				bsp_board_led_on(1);
				bsp_board_led_on(2);
				err_code = app_timer_start(m_leds_timer_id, APP_TIMER_TICKS(1000), NULL);
			break;

		case BSP_INDICATE_ALIVE:
				bsp_board_led_on(2);
				err_code = app_timer_start(m_leds_timer_id, APP_TIMER_TICKS(50), NULL);
			break;
					
        default:
            break;
    }

    return err_code;
}

Hi 114r5,

It seems like you have a debouncing issue.

I would recommend you to check out the "Button handling library" and especially how this is done in the BSP example.
