Pairing & Unpairing Bluetooth Devices with Windows Phone

Pairing a Windows Phone to another Bluetooth enabled device is pretty easy to do, but you might be disappointed when you do it.  When I got my first Windows Phone – a Samsung Focus (WP7) – one of the first things I tried to do was pair it with my Bluetooth keyboard.  The phone paired just fine, but nothing I typed on my keyboard showed up on my phone. After researching the problem I realized that the phone was missing the HID profile, which it needed to know what to do with the keyboard after the pairing was achieved! 

Bluetooth profiles possess the “capabilities” that enable a Bluetooth connected device to interpret and act on the commands received from another Bluetooth connected device.  In order for the Bluetooth radio in a receiving device to translate and act on the commands sent from another Bluetooth device, it must possess a compatible profile as the sending device.

The Samsung Focus does not include the Bluetooth HID profile (Human Interface Device) that would enable it to connect to and use external devices like mice or keyboards…..and unfortunately even today the latest Windows Phone 8.1 devices do not include this profile so I still can’t use my bluetooth keyboard with my phone.

In this article I’ve provided a list of the Bluetooth Profiles that are supported on Windows Phone, and I’ve demonstrated how to pair and unpair a Windows Phone with another Bluetooth enabled device.
