I’m not having any luck with getting the Bluetooth advertising to stay running.

I’m using VS.NET 2019 with Tizen 4.0 as the target.  The device I’m deploying to is a Samsung Galaxy Active2 watch.

The advertising starts ok, and I can see a few packets, but then it just stops by itself.

Here is the code (mostly just copied from this guide: docs.tizen.org/application/dotnet/guides/connectivity/bluetooth):

            BluetoothLeAdvertiseData advertiseData = new BluetoothLeAdvertiseData();

            advertiseData = new BluetoothLeAdvertiseData();
            advertiseData.AdvertisingMode = BluetoothLeAdvertisingMode.BluetoothLeAdvertisingBalancedMode;
            advertiseData.AdvertisingConnectable = true;
            advertiseData.Appearance = 192;

            BluetoothLePacketType packetType = BluetoothLePacketType.BluetoothLeAdvertisingPacket;
            string serviceUuid = “1805”; /// time_svc_uuid_16
            advertiseData.AddAdvertisingServiceUuid(packetType, serviceUuid);

            /// Add sample service data for testing
            BluetoothServiceData serviceData = new BluetoothServiceData();
            serviceData.Uuid = “1805”;
            serviceData.DataLength = 3;
            serviceData.Data = new byte[3] { 0x01, 0x02, 0x03 };
            advertiseData.AddAdvertisingServiceData(packetType, serviceData);

            advertiseData.IncludeDeviceName = true;
            advertiseData.IncludeTxPowerLevel = true;

            advertiser.StartAdvertising(advertiseData);

And here is what I see in the Tizen debug log:
