我想到了。 我走在正確的軌道上。

使用以下連接后：

var dev = await BluetoothLEDevice.FromBluetoothAddressAsync(args.BluetoothAddress);

您需要執行自定義配對：

var prslt = await device.DeviceInformation.Pairing.Custom.PairAsync(DevicePairingKinds.ProvidePin, DevicePairingProtectionLevel.None);

但這只會給您一個錯誤。 您還必須創建device.DeviceInformation.Pairing.Custom.PairingRequested事件處理程序。

所以我創建了這個處理程序：

private void handlerPairingReq(DeviceInformationCustomPairing CP, DevicePairingRequestedEventArgs DPR)

{

//so we get here for custom pairing request.

//this is the magic place where your pin goes.

//my device actually does not require a pin but

//windows requires at least a "0". So this solved

//it. This does not pull up the Windows UI either.

DPR.Accept("0");

}

在PairAsync調用之前將其連接起來，例如：

device.DeviceInformation.Pairing.Custom.PairingRequested += handlerPairingRequested;

連接我的BlueToothAdvertisementWatcher代碼的示例代碼：

private BluetoothLEAdvertisementWatcher BTWatch = new BluetoothLEAdvertisementWatcher();

private void Inits()

{

BTWatch.Received += new TypedEventHandler(BtAddRx);

BTWatch.Start();

}

private async void BtAddRx(BluetoothLEAdvertisementWatcher bw, BluetoothLEAdvertisementReceivedEventArgs args)

{

GattCommunicationStatus srslt;

GattReadResult rslt;

bw.Stop();//Stop this while inside.

device = await BluetoothLEDevice.FromBluetoothAddressAsync(args.BluetoothAddress);

if (device.DeviceInformation.Pairing.IsPaired == false)

{

/* Optional Below - Some examples say use FromIdAsync

to get the device. I don't think that it matters. */

var did = device.DeviceInformation.Id; //I reuse did to reload later.

device.Dispose();

device = null;

device = await BluetoothLEDevice.FromIdAsync(did);

/* end optional */

var handlerPairingRequested = new TypedEventHandler(handlerPairingReq);

device.DeviceInformation.Pairing.Custom.PairingRequested += handlerPairingRequested;

log("Pairing to device now....");

var prslt = await device.DeviceInformation.Pairing.Custom.PairAsync(DevicePairingKinds.ProvidePin, DevicePairingProtectionLevel.None);

log("Custom PAIR complete status: " + prslt.Status.ToString() + " Connection Status: " + device.ConnectionStatus.ToString());

device.DeviceInformation.Pairing.Custom.PairingRequested -= handlerPairingRequested; //Don't need it anymore once paired.

if (prslt.Status != DevicePairingResultStatus.Paired)

{ //This should not happen. If so we exit to try again.

log("prslt exiting. prslt.status=" + prslt.Status.ToString());// so the status may have updated. lets drop out of here and get the device again. should be paired the 2nd time around?

bw.Start();//restart this watcher.

return;

}

else

{

// The pairing takes some time to complete. If you don't wait you may have issues. 5 seconds seems to do the trick.

System.Threading.Thread.Sleep(5000); //try 5 second lay.

device.Dispose();

//Reload device so that the GATT services are there. This is why we wait.

device = await BluetoothLEDevice.FromIdAsync(did);

}

var services = device.GattServices;

//then more code to finish it up.

}

如果您想斷開連接，請使用：

await device.DeviceInformation.Pairing.UnpairAsync();

抱歉，代碼混亂。 如果發現有人有用或有疑問，請告訴我。 我在任何地方都找不到此代碼的任何WinForm示例。 實際上，在沒有UI的情況下，我找不到任何代碼來顯示如何與PIN配對。 因此，我希望這對任何可能陷入困境的人有所幫助。
