Hi,

Error code 0x08 means NRF_ERROR_INVALID_STATE, and is returned by the GPIOTE driver init function if the driver is already initialized.

ble_app_uart example make use of the BSP library, which again use the application button library. The button library already initialize GPIOTE driver. You could add a check to make sure you do not initialize the driver if it is already initialized:

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

Best regards,
Jørgen
