Interrupt Callback nRF52805 ble_app_beacon

Question

I working with the MDBT42Q-DB with the nRF52805 module. I've started from the ble_app_beacon example in SDK 17.1.0. I was able to compile and run the example in Segger Studio. I wasn't able to get things to work with Keil.

I'm trying to modify the example to added button response for my onboard buttons. Ultimately I'd like a button (input) to trigger a wake-up for several minutes (setting a timer) before allowing the beacon to go back into deep sleep.

I modified the pca10050.h to match the pin configuration of the development board:

#define LEDS_INV_MASK  LEDS_MASK

#define LEDS_LIST { LED_1, LED_2 }

#define BSP_LED_0      LED_1
#define BSP_LED_1      LED_2

#define BUTTONS_NUMBER 4

#define BUTTON_1       12
#define BUTTON_2       11
#define BUTTON_3       9
#define BUTTON_4       13
#define BUTTON_PULL    NRF_GPIO_PIN_PULLUP

#define BUTTONS_ACTIVE_STATE 0

#define BUTTONS_LIST { BUTTON_1, BUTTON_2, BUTTON_3, BUTTON_4 }

#define BSP_BUTTON_0   BUTTON_1
#define BSP_BUTTON_1   BUTTON_2
#define BSP_BUTTON_2   BUTTON_3
#define BSP_BUTTON_3   BUTTON_4

I added BSP_INIT_BUTTONS and a callback handler for button presses in the leds_init fucntion

void bsp_event_handler(bsp_event_t event)
{
    printf("Event");
    switch(event)
    {
        case BSP_EVENT_KEY_0:
        case BSP_EVENT_KEY_1:
        case BSP_EVENT_KEY_2:
        case BSP_EVENT_KEY_3:
            printf("Event");
            break;
        default:
            break;
    }
}


/**@brief Function for initializing LEDs. */
static void btn_leds_init(void)
{
    ret_code_t err_code = bsp_init( BSP_INIT_LEDS | BSP_INIT_BUTTONS, bsp_event_handler);
    APP_ERROR_CHECK(err_code);
}

/**
 * @brief Function for application main entry.
 */
int main(void)
{
    bsp_event_t startup_event;

    log_init();
    timers_init();
    btn_leds_init();

    power_management_init();
    ble_stack_init();
    advertising_init();

    // Start execution.
    NRF_LOG_INFO("Beacon example started.");
    advertising_start();


    // Enter main loop.
    for (;; )
    {
        idle_state_handle();
    }
}

I've enable logging which suggests everything got initialized properly. The ble_beacon is advertising the custom UUID i've set at the interval I've set both of which I can modify.

<info> PRS: Function: nrfx_prs_acquire, error code: NRF_SUCCESS.
<info> app_timer: RTC: initialized.
<info> GPIOTE: Function: nrfx_gpiote_init, error code: NRF_SUCCESS.
<info> GPIOTE: Function: nrfx_gpiote_in_init, error code: NRF_SUCCESS.
<info> GPIOTE: Function: nrfx_gpiote_in_init, error code: NRF_SUCCESS.
<info> GPIOTE: Function: nrfx_gpiote_in_init, error code: NRF_SUCCESS.
<info> GPIOTE: Function: nrfx_gpiote_in_init, error code: NRF_SUCCESS.
<info> CLOCK: Function: nrfx_clock_init, error code: NRF_SUCCESS.
<info> clock: Function: nrf_drv_clock_init, error code: NRF_SUCCESS.
<info> app: Beacon example started.

I confirmed that the pull-up on SW3 (only default connected switch to pin 9) is being configured with a pull-up as expected.

The status LED is blinking as expected with the advertising indication so I at least modified the LED pins properly.

It's possible some of my configuration, porting the project from pca10040e to support the rNF52805 wasn't completely done properly. I followed this guide as best I could, but as mentioned about I wasn't successful getting Keil to run, though it seemed to compile. Segger studio is at least running with some working.

I was using this guide:

https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/developing-for-the-nrf52805-with-nrf5-sdk

I put the full project here:

Can you perhaps provide some direction? I cannot seem to get any sort of interrupt response from the board.
