never call "app_button_is_pushed()" function in ble-lbs-master project

[HSA]

Hello Nordic,

I am trying debugging on following project [--ble_app_lbs_master--]. During debugging, I never reach at app_button_is_pushed function. I tried pressing the button while debugging and in connected state.

Actually I want to read the button_pin_status (value) in between when button pressed and button detected. How can I do that?

Please suggest valuable suggestions.

Thanks n Regards

Update1: @Aryan: Please find the attached app_button.x file.app_button.c

Update2: @Aryan:

uint32_t app_button_init(app_button_cfg_t * p_buttons, uint8_t button_count, uint32_t detection_delay)

There was a PAN that on OUTINIT on some hardware IC rev and the workaround for it was removed from SDK from 8.0.0.

in SDK9.0 and SDK 8.1, nrf_gpiote.h nrf_gpiote_task_configure needs a fix for the above to work. update it with this code and let me know if it works.

__STATIC_INLINE void nrf_gpiote_task_configure(uint32_t idx, uint32_t pin,
                                                nrf_gpiote_polarity_t polarity,
                                                nrf_gpiote_outinit_t  init_val)
{
    /* Check if the output desired is high or low */
    if (init_val == NRF_GPIOTE_INITIAL_VALUE_LOW)
    {
        /* Workaround for the OUTINIT PAN. When nrf_gpiote_task_config() is called a glitch happens
        on the GPIO if the GPIO in question is already assigned to GPIOTE and the pin is in the 
        correct state in GPIOTE but not in the OUT register. */
        NRF_GPIO->OUTCLR = (1 << pin);

        /* Configure channel to Pin31, not connected to the pin, and configure as a tasks that will set it to proper level */
        NRF_GPIOTE->CONFIG[idx] = (GPIOTE_CONFIG_MODE_Task       << GPIOTE_CONFIG_MODE_Pos)     |
                                             (31UL                          << GPIOTE_CONFIG_PSEL_Pos)     |
                                             (GPIOTE_CONFIG_POLARITY_HiToLo << GPIOTE_CONFIG_POLARITY_Pos);                                    
    } 
    else 
    {

Hello @Aryan,

I tried the same. It doesn't stop at the --app_button_is_pushed-- function, even with and without button press.

It always comes at [// Pushed button(s) detected, execute button handler(s)] here.

Please suggest.
