+Console utility to discover and pair Bluetooth and Bluetooth Low Energy devices.
+
+# Note on connecting to Bluetooth devices
+If you pair a device which is not already paired, the utility will also connect to it (this is default behaviour of Windows Bluetooth API)<br>
+However, if device is paired but not connected, the pairing will fail.<br>
+Unfortunately, currently it is not possible to simulate what "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](https://stackoverflow.com/questions/62502414/how-to-connect-to-a-paired-audio-bluetooth-device-using-windows-uwp-api). Specifically, [here](https://github.com/inthehand/32feet/issues/132#issuecomment-1019786324) I have described my failed attempts to implement this functionality.<br>

 # How it works
-The program uses [Windows.Devices.Enumeration API](https://docs.microsoft.com/en-us/uwp/api/Windows.Devices.Enumeration?redirectedfrom=MSDN&view=winrt-22000) to work with Bluetooth.

-## Device pairing by mac
-The utility gets the default bluetooth adapter and generates the bluetooth device id using combination of bluetooth type, adapter mac address and device's mac address. Using this id, it is possible to request to pair or unpair the device.
