button event handler not firing

[asma]

Hello EveryOne

My button event handler is not being called. following is my code what can be the problem.

uint32_t err_code;


    ble_stack_init();

    timers_init();

    APP_GPIOTE_INIT(1);	

    buttons_init();

    device_manager_init();

    gap_params_init();

    advertising_init();

    services_init();

    conn_params_init();

    Therapy_Init();

    Diagnosis_Init();
    ADC_Init();	

    Pstorage_Initialization();

    // Start detecting button presses.
	err_code = app_button_enable();
    APP_ERROR_CHECK(err_code);

my buttons_init code

static app_button_cfg_t buttons[] =
    {
      17, false, NRF_GPIO_PIN_PULLUP, button_events_handler};

  APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, false);}

i have also enabled app_button_enable but then also handler is not getting called.

Hi Asma

I am not sure why your pstorage is not working together with app_button library. Does the app_button operation by any chance block the operation of the flash operation? What do you do in your app_button handler?

You could find out if your pstorage operation is actually writing something to flash, see this thread.

There is an example code here for pstorage. Perhaps you can compare your code with that code.

What SDK and SD are you using?

Can you check content of the flash area that you are writing after you have written it with the methods that I pointed to earlier? Do you get a callback for the pstorage operation indicating that it is complete? Set a breakpoint in the pstorage callback function to see that the callback is received. If it is received, read the memory content with nrfjprog as instructed on the linked thread.
