app_button does not work on my project

[MeliodasD]

Hi there,

I am porting the the app_button from the ble_blinky project to my own project which uses BLE functionality too, and it is not firing the button_event_handler after pressed a button.

I am calling initialize() from my main.c to initialize the timer, leds and buttons

below my code:

#define NRF_LOG_MODULE_NAME Peripheral
#include "nrf_log.h"
#include "nrf_log_ctrl.h"
NRF_LOG_MODULE_REGISTER();

#include "peripheral.h" // header for the functions here
#include "boards.h"
#include "app_timer.h"
#include "app_button.h"

#define LEDBUTTON_BUTTON                BSP_BUTTON_0                            /**< Button that will trigger the notification event with the LED Button Service */
#define BUTTON_DETECTION_DELAY          APP_TIMER_TICKS(50)                     /**< Delay from a GPIOTE event until a button is reported as pushed (in number of timer ticks). */

	static void timers_init(void)
	{
		ret_code_t err_code = app_timer_init();
		APP_ERROR_CHECK(err_code);
	}
	static void leds_init(void)
	{
		bsp_board_init(BSP_INIT_LEDS);
	}
	static void button_event_handler(uint8_t pin_no, uint8_t button_action)
	{
		ret_code_t err_code;
		NRF_LOG_INFO("button_event_handler");
		switch (pin_no)
		{
		case LEDBUTTON_BUTTON:
			NRF_LOG_INFO("Button .");

			break;

		default:
			APP_ERROR_HANDLER(pin_no);
			break;
		}
	}
	static void buttons_init(void)
	{
		ret_code_t err_code;
		static app_button_cfg_t buttons[] =
		{
			{ LEDBUTTON_BUTTON, false, BUTTON_PULL, button_event_handler }
		};

		err_code = app_button_init(buttons,	ARRAY_SIZE(buttons),BUTTON_DETECTION_DELAY);	
		APP_ERROR_CHECK(err_code);
	}
	void initialize()
	{
		leds_init();
		timers_init();
		buttons_init();
		app_button_enable();
	}

SDK15.2

sdk_config:.

NRFX_CLOCK_ENABLED 1

NRFX_GPIOTE_ENABLED 1

APP_TIMER_ENABLED 1

BUTTON_ENABLED 1

I added nrf_drv_clock.c ,nrfx_clock.c, nrfx_gpiote.c, app_button.c, app_timer.c and their headers to my project with no luck

if someone can give me an advise, thanks in advance

Hello,

 

my own project which uses BLE functionality too

 Are you using a custom board or are you using a Nordic Semiconductor development kit? If using a custom board, is the button active high or active low? Please ensure that you have configured the button correctly i.e. Pull up/down and sense low/high accordingly. The current configuration has pull-up enabled with sense low, based on the Development Kits which have buttons Active Low.

Other than that everything looks ok to me. If you need more buttons, you may follow instructions in this Thread.

Best regards,

Oeyvind

Hi Øyvind, I am still running my project on a nR52DK, I think my issue should be something that I missing, to enable or related to app_button_enable

[MeliodasD]

I solved my issue, I was trying to use the buttons before initialize the softdevice or a source clock were enabled (LFCLK)

after initialized my clock source the buttoms works fine

Glad to hear!
