And I choose template-app. And I write this code :
Code: Select all

};
// GAP callback

}
else printf("Unable to start advertising process, error code %d\n\n", param->scan_start_cmpl.status);
break;

}
}
void app_main() {

// initialize Bluedroid library

// register GAP callback function

ESP_ERROR_CHECK(esp_ble_gap_set_device_name("Sport_Device"));
ESP_ERROR_CHECK(esp_ble_gap_config_adv_data(&adv_data));
printf("- ADV data configured\n\n");
}How can I solve this problem? Thanks
