hello ，im using Bluetooth wifi config code

```auto
void setup() {
    Serial.begin(115200);

    BLE.init();
    BLE.configServer(1);
    configService.addService();
    configService.begin();

    // Wifi config service requires a specific advertisement format to be recognised by the app
    // The advertisement needs the local BT address, which can only be obtained after starting peripheral mode
    // Thus, we stop advertising to update the advert data, wait for advertising to stop, then restart advertising with new data
    BLE.beginPeripheral();
    BLE.configAdvert()->stopAdv();
    BLE.configAdvert()->setAdvData(configService.advData());
    BLE.configAdvert()->updateAdvertParams();
    delay(100);
    BLE.configAdvert()->startAdv();

}

```

it can config wifi ok but restart bw16 cant auto connect wifi ，please let me know how to do that thanks。

Hi @kal

WiFi network automatic save to flash and automatic reconnect from flash is a feature that is not present in the Arduino SDK. If you need this feature, you can consider using [GitHub Standard SDK](https://github.com/ambiot/ambd_sdk/), which includes WiFi save and auto reconnect, as well as BLE WiFi Config.
