Console utility to discover and pair Bluetooth and Bluetooth Low Energy devices.

If you pair a device that is not already paired, the utility will also connect to it (this is the default behavior of Windows Bluetooth API)
However, the pairing will fail if a device is paired but not connected.
Unfortunately, it is impossible to simulate what the "Connect" button from Windows Bluetooth and Other devices dialog does. More details can be found here: How to connect to a paired audio Bluetooth device. Specifically, here I have described my failed attempts to implement this functionality.

Windows 10 1809 (10.0.17763) or higher

• Download and unpack the latest release.
• Run BluetoothDevicePairing.exe --help and BluetoothDevicePairing.exe <command> --help to get usage information and check the Examples section below.

• Discover devices:

BluetoothDevicePairing.exe discover

• Pair a device using its Mac address:

BluetoothDevicePairing.exe pair-by-mac --mac 12:34:56:78:9A:BC --type Bluetooth

• Pair a device using its name:

BluetoothDevicePairing.exe pair-by-name --name "MX Ergo" --type BluetoothLE

• Pair a device using its name and pin code:

BluetoothDevicePairing.exe pair-by-name --name "Device name" --type BluetoothLE --pin 1234

• Pair a device using its Mac and pin code:

BluetoothDevicePairing.exe pair-by-mac --mac 12:34:56:78:9A:BC --type Bluetooth --pin 1234

• Unpair a device using its Mac address:

BluetoothDevicePairing.exe unpair-by-mac --mac 12:34:56:78:9A:BC --type Bluetooth

• Unpair a device using its name:

BluetoothDevicePairing.exe unpair-by-name --name "MX Ergo" --type BluetoothLE

• List all Bluetooth adapters available to your machine

BluetoothDevicePairing.exe list-adapters

The BluetoothDevicePairing utility can be used in bat and PowerShell scripts.

The following bat script allows to automate the connection of Bluetooth devices. Before using this script, you need to find out the Bluetooth type and name of your device:

1. Put the device into the pairing mode
2. Run the BluetoothDevicePairing.exe discover command that will print the required information.
3. Adapt the script below to use your device's name and Bluetooth type.

How to use the script:

1. Put the device into a pairing mode
2. Run the script

C:\my\apps\BluetoothDevicePairing.exe unpair-by-name --name "MX Ergo" --type BluetoothLE --discovery-time 1
C:\my\apps\BluetoothDevicePairing.exe pair-by-name --name "MX Ergo" --type BluetoothLE --discovery-time 10
if %ErrorLevel% NEQ 0 (
    pause
    exit /b %errorlevel%
)

The program uses

• Windows.Devices.Enumeration API to work with Bluetooth.
• Costura Fody to create a single file executable.

To pair a device by name, the utility starts by discovering all available devices and tries to find a device with the required name. After a device is found, its Mac address is used to request pairing. The command will fail if there are several devices with the same name.

If the command fails, it returns the value -1. If it succeeds, it returns 0.

• Use Visual Studio 2022 to open the solution file and work with the code
• Run .github/workflows/build.ps1 to build a release (to run this script, git.exe should be in your PATH)
