My Phone

My Phone is a desktop application that allows you to link your phone (supports Android, iOS, and Windows Phone) to your Windows 10/11 PC via Bluetooth without having to install a companion app on your phone.

Implementation

Hands-Free Profile (HFP)

This app use Windows Runtime APIs: Windows.ApplicationModel.Calls , Windows.Devices.Bluetooth and Windows.Devices.Enumeration to make the HFP works.

  1. Use Windows.Devices.Enumeration API to enumerate available PhoneLineTransportDevice (i.e. paired Bluetooth devices that support HFP),
  2. Call PhoneLineTransportDevice.RegisterApp to register the device for HFP
  3. Call PhoneLineTransportDevice.Connect to connect to the deivice (establishes HFP Service Level Connection).
  4. Now you can receive and answer phone calls on your PC.
  5. To make phone call, use Windows.Devices.Enumeration API to enumerate available PhoneLine, then call PhoneLine.Dial

Note that Microsoft's Phone Link use the same APIs mentioned above.

The HFP stack

The above APIs have very limited functionality. They can only be only used for call control. If you need to handle raw audio stream or something else, you need to write a custom user-mode profile driver (more information here).

Actually, I did try to implement HFP stack before but eventually gave up because the MSIX package does not support installing drivers. I managed to establish the HFP Service Level Connection (SLC) and successfully make the phone call via SLC, but failed to establish SCO audio connection and transfer any audio. If you're interested in how to establish HFP Service Level Connection, you may find the source code here.
