button handler interrupt - nrf52840 dongle

Hello,

I guess it is a simple problem, but I am new to the nrf world, so here is my issue: 

 

#include <stdint.h>
#include <string.h>
#include "nordic_common.h"
#include "boards.h"
#include "pca10059.h"
#include "app_timer.h"
#include "app_button.h"
#include "app_scheduler.h"

static void button_handler(uint8_t pin, uint8_t action)
{
    if (pin == BSP_BUTTON_0){
        if (action == APP_BUTTON_PUSH){
            bsp_board_led_on(BSP_BOARD_LED_0);
        } else if (action == APP_BUTTON_RELEASE){
            bsp_board_led_off(BSP_BOARD_LED_0);
        }
    }
}

/**@brief Function for application main entry.
 */
int main()
{
    bsp_board_init(BSP_INIT_LEDS);
    app_timer_init();
    //The array must be static because a pointer to it will be saved in the button handler module.
    static app_button_cfg_t buttons[] =
    {
        {BSP_BUTTON_0, false, BUTTON_PULL, button_handler}
    };
    app_button_init(buttons, ARRAY_SIZE(buttons), APP_TIMER_TICKS(50));
    app_button_enable();
}
/**

I want to use this code to switch on a LED by pressing the on board button (BSP_BUTTON_0) on my nrf dongle. But when I run it and press the button, no interrupt is fired and nothing happens. But if I add a softdevice and add 

nrf_sdh_enable_request();

to my main, it works perfectly. So, is there a way to get this code running without any softdevice? And why is it just working with it?

Thanks

Maboo

Ps: I am using SDK17 on Linux, VS Code

  • I am new to the nrf world

    It would be a lot easier to start on a Development Kit (DK) - rather than the dongle.

    is there a way to get this code running without any softdevice?

    yes:  the SDK has examples of using the chip as just a microcontroller - with no BLE

    why is it just working with it?

    What else is in your code? Is it getting stuck in something which does require the softdevice?

  • Thanks for your quick response. 

    That is all the code I use, I striped the ble_app_blinky example, deleted all sdh includes and tested it as it is.

    Switching on a LED in my main works, but not in button_handler. Can it have something to do with my makefile or sdk_config.h, do i have to enable or disable something? 

    makefile:

  • Thanks for your quick response. 

    That is all the code I use, I striped the ble_app_blinky example, deleted all sdh includes and tested it as it is.

    Switching on a LED in my main works, but not in button_handler. Can it have something to do with my makefile or sdk_config.h, do i have to enable or disable something? 

    makefile:
