蓝牙配网是不支持断电重连吗，还是我设置错误了，那这个配网只能一次性的？没搞懂，哪个大神看看，应该说配网信息应该是保存到flash，上电以后自动重连才是。
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();
