Hi,

Most likely you get an error because the GPIOTE driver has already been initialized (by app_button module used by the BSP library).

You can try this approach to check if the driver is initialized before initializing it:

if (!nrf_drv_gpiote_is_init())
{
    err_code = nrf_drv_gpiote_init();
    APP_ERROR_CHECK(err_code);
}

Best regards,
Jørgen
