What determines the parameter DevicePairingRequestedEventArgs in \Windows-universal-samples-master\Samples\DeviceEnumerationAndPairing

What determines the parameters DevicePairingRequestedEventArgs in \Windows-universal-samples-master\Samples\DeviceEnumerationAndPairing ?

I want to custom pair BLE device which with static PIN code, but the parameter( args.PairingKind) from PairingRequestedHandler always be the value "ConfirmOnly",
and the value I expected is "providepin" or "providepasswordcredential" that I can input PIN code.

What determines this parameter ？ The master BLE app or the BLE device to be paired ?

Hi, ZhiguoHu
Welcome to Microsoft Q&A

What determines this parameter ?

For this problem you could check DeviceEnumerationAndPairing code sample Scenario9 CustomPairDevice, if you have specific pairingKindsSupported for PairAsync method where in
line 136. And above will determines args.PairingKind parameter.

The master BLE app or the BLE device to be paired ?

It can be paired for BLE device. you could use above sample and edit device selector to Bluetooth LE. For BLE app, may you need provide more info about it.

Thank you for your reply.

That's what I did before.(check DeviceEnumerationAndPairing code sample Scenario9 CustomPairDevice)

"Select supported pairing ceremonies:" have 5 checkboxes, if I do not select "ConfirmOnly" and select all others,
The app cannot enter function PairingRequestedHandler, and it prompt the function is not registered
(RequiredHandlerNotRegistered = 16, and DevicePairingKinds not be supported),
My test BLE device PIN password is setted.
If ceremony option "ConfirmOnly" is selected, The app can run enter PairingRequestedHandler,
but I hope the parameter( args.PairingKind) from PairingRequestedHandler is "providepin" or "providepasswordcredential" that I can input PIN code.

I want to know what factors determines the parameter DevicePairingRequestedEventArgs PairingKind,
The master BLE app or the my test BLE device ? I hope you understand my problem. Thanks.

The ble device is nrf52840 moudle from taobao (https://item.taobao.com/item.htm?spm=a1z09.2.0.0.14782e8dHRHpYL&id=553764237720&_u=s23rvpc0e869),
Software nRF5_SDK from nordicsemi.
Maybe, the parameter DevicePairingRequestedEventArgs PairingKind is determined by nrf52840 or it's software SDK,
not by the ble master or UWP app.
Perhaps we can generate the correct "providepin" option by modifying the device software SDK.

Thanks.

Yep, you are correct, if the device does not support providepin option, PairingKind.ProvidePin will not available.

I asked nordicsemi for support , and they replied that there is no problem of my SDK configuration.

I use android phone as master bluetooth to test the connection of nrf52840 ble device,
A pin-code-input dialog box ejectted as my expected, and the communication is normal after pairing.

I use win10 built-in bluetooth scanning and pairing function to connect nrf52840 ble device,
the result show that the pairing is finished and OK,but in fact, the communication can not work properly.

I use win10 built-in bluetooth scanning and pairing function to connect other classic bluetooth device,
A pin-code-input dialog box ejectted as my expected, and the communication is normal after pairing.

Did you test UWP app with your mobile phone in ble mode?
Can you use win10 built-in bluetooth scanning and pairing function to test ble device ?
Why can't win10's built-in functions pair correctly?

I have no such device, so I tested with my phone to connect to my pc. Why don't you use BluetoothLEAdvertisementWatcher to watch the ble's Advertisement?

My main problem is custom pairing BLE device which with static PIN code setted,
and hope to appear a pin-code-input dialog box like option ""providepin".
Using win10 built-in bluetooth to scan and pair is only to test win10 pairing BLE process.
Using BluetoothLEAdvertisementWatcher to watch the ble's Advertisement can not solve my problem.
Through these tests, I doubt that there may be a bug in the handling of win10 custom pairing ble device which with static PIN code.

If you like, please email me your shipping address and I will send BLE device board to you by express to have real test.

OK, thank you for your response.
I have a little doubt that win10 system pairing ble only by default option "ConfirmOnly",
Whether the static pin-code is set or not.
I hope that you and your team to find the problem and give the solution as soon as possible.
Thanks again.

Your issue that might be related to some specific BLE devices and I'm afraid is not suitable to discuss in the Forum. It is not allowed for us to tell you about our the email or address and we also won't ask you for private information. For your scenario, I suggest that you might need to open a support ticket for this. Please contact our paid phone support at MS Support. You will get 1:1 support on that. Select Developer Tools -> Windows UWP Development -> Windows 10 Universal App Dev -> Devices and Sensors Development-> Bluetooth API in the support page and you could contact the team. Please kindly note that your support ticket will be free if it is Microsoft's issue.
