Button events are not triggered on NRF52840 Dongle

I don't have any other suggestion than to follow one of the example or tutorials:
https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/board-support-package-bsp

And please get an nRF52840-DK so you know the code works to begin with.

yes - I have followed that and that thread does not provide the solution. So from Nordic standpoint, what should be the correct code to invoke a button event handler for the dongle button. Can you please make it clear once and for all?

Somehow I check the forum and I am confused why we have the same answer? :-) Even if I use the DK for the development, and test one of the buttons, I would ultimately would want to port the .hex to Dongle and test that button So how would it work if I am not referencing the correct button in dongle?

why is it so difficult to just click a button and control the behavior via event. It is not specific to zigbee or BLE or anything, just simple click of a button should light up an onboard LED

Hi,

Some of the examples can be used with the nRF52840 Dongle, however since the dongle don't contain a debugger/programmer I don't recommend to use it for any development. I strongly recommend to get an nRF52840-DK for development:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fzigbee_only_examples.html

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fzigbee_multi_examples.html

The light switch example that you are working on is not supported by the dongle, I believe for instance the light switch use 4 buttons, while the dongle have 1.

Best regards,
Kenneth

Okay - here is a bit of modification done - but strange bahaviour

1. After the .hex is loaded on the dongle, the Board LED lights up red, which means that the APP_BUTTON_PUSH is invoked automatically! How?. Further pushing / release the dongle button has no affect, the led just stays red. I was obviously expecting the corresponding color of the led to lit up when button is pressed / releases as handled in button_evt_handler

2. The detection delay in the method app_button_init (defined using ZB_MILLISECONDS_TO_BEACON_INTERVAL(154)) has a strange behaviour. The led lights up only when the value is 154 and above.

#define LIGHT_SWITCH_BUTTON_LONG_POLL_TMO   ZB_MILLISECONDS_TO_BEACON_INTERVAL(154)

static void button_evt_handler(uint8_t pin_no, uint8_t button_action)
{
    switch(pin_no)
    {
        case BSP_BOARD_BUTTON_0:
          if(button_action == APP_BUTTON_PUSH) 
          {
            bsp_board_led_on(BSP_BOARD_LED_1); // 1- Red
          }
          else if(button_action == APP_BUTTON_RELEASE) 
          {
            bsp_board_led_on(BSP_BOARD_LED_2); // 2- Green
          }
          break;
        default:
          bsp_board_led_on(BSP_BOARD_LED_3); // 3-Blue
          return;
    }
}

{
    uint32_t err_code;

    static app_button_cfg_t buttons[] = 
    { 
        {BSP_BOARD_BUTTON_0, false, BUTTON_PULL, button_evt_handler}
    };

    err_code = app_button_init(buttons, ARRAY_SIZE(buttons), LIGHT_SWITCH_BUTTON_LONG_POLL_TMO);
    APP_ERROR_CHECK(err_code);

    err_code = app_button_enable();
    APP_ERROR_CHECK(err_code);
}
