我希望实现启动自动配网的功能，下面是我的代码。

我第一版代码没有增加判断，只是通过蓝牙BLE进行了配网，完成后可以看到IP地址出现，证明网络已经连接成功。
但是我希望可以让设备启动后自动联网，就增加了

static void wifi_init_sta(void)
{
/* Start Wi-Fi in station mode */
ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
ESP_ERROR_CHECK(esp_wifi_start());
}

还有man函数内加了。
bool provisioned = false;
if (!provisioned)
{
ESP_LOGI(TAG, "Starting provisioning");

/* What is the Device Service Name that we want
* This translates to :
* - Wi-Fi SSID when scheme is wifi_prov_scheme_softap
* - device name when scheme is wifi_prov_scheme_ble
*/
char service_name[60];
get_device_service_name(service_name, sizeof(wifi_sta_config_t));


}
else{

/* We don't need the manager as device is already provisioned,
* so let's release it's resources */
wifi_prov_mgr_deinit();

/* Start Wi-Fi station */
wifi_init_sta();
}



问题：现在启动后 error: implicit declaration of function 'get_device_service_name' [-Werror=implicit-function-declaration]
96 | get_device_service_name(service_name, sizeof(wifi_sta_config_t));


如果我去掉。get_device_service_name(service_name, sizeof(wifi_sta_config_t)); 第二次上电又无法连接WiFi。
