Hi,

You can see in the infocenter page here, that when the nrf_drv_gpiote_init() function returns NRF_ERROR_INVALID_STATE, that means that the GPIOTE module was already initialized. This previously initialization of the module was done by the function buttons_leds_init().

I recommend using the function nrf_drv_gpiote_is_init() to make sure that you don't try to initialize the module if it’s already initialized:

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