Bluetooth Keyboard PIN

i have exactly  same  problem and that reply above did not help

Para resolver este problema com o PIN, vai até o painel de controle, Dispositivos e impressoras, e clica em Adicionar um dispositivo:

Quando clicar em avançar também vai pedir o Pin, embaixo vai ter um link para digitar no aparelho, é só clicar, digitar e dar enter. 

Não consegui o print pq já tinha me conectado :(

Att,

If that's the case, you may need to reset your phone to get this sorted out. This process will remove everything stored on your phone, so make sure to create a backup before proceeding to avoid data loss. To reset your phone, go to System > About > Reset your phone.

Alternately, we request that you file this on our Windows Feedback Hub app so that our dedicated team will have a visibility of the issue you're experiencing.

To submit a new feedback, you can follow the steps below:

1. Go to All Apps, search for the Feedback Hub app or press and hold Volume Down+Power button for about 2-3 seconds to launch the app.
2. Open the menu icon at the top left side.
3. Select Feedback, then at the top right side, tap the add button (+).
4. Select Problem and fill up the box with the details needed.
5. Select the right category for the problem and then submit.

We're here if you have other concerns.

These solutions were already readily available in other documentation and did not work.  As I stated before "it appears that I need to wipe out the Win10 device's previous association with the BT keyboard so that I can start the pairing process again, but I cannot find any documentation on how to do that."

The device is NOT currently listed as a under "Bluetooth & other devices", so it can't be removed.  However, despite not being listed under Bluetooth & other devices, the devices is being treated by my phone as if it is already paired and is simply asking for the existing PIN.

There is no default PIN for this device.  As I noted before, when I connected to an Android device, it generated a PIN.  I also attempted to connect the device to my Win10 laptop and it also generated PIN number (see attached image).

The problem is that I have previously attempted to pair my Win10 mobile device and the pairing process timed out before I was able to enter the PIN.  So it now appears that it is expecting me to type in a PIN that my Win10 phone previously briefly gave me, but for which I do not remember and had no means to record.

Hello,

Usually, the default PIN is "0000" or "1234". You may also be able to find the PIN on the accessory itself or check the documentation for the accessory. Note that when you’re pairing a Bluetooth keyboard with your phone, you’ll often be prompted to enter a passcode on the keyboard itself to make sure you’re pairing with the correct device. When you’re done typing the passcode on the keyboard, make sure you press Enter on the keyboard.

If you're trying to restart the pairing process of your Bluetooth device, go to Settings > Devices > Bluetooth & other devices and select the device you want to remove, then select Remove device.
