BTstack port for Windows Systems using the WinUSB Driver

The Windows-WinUSB port uses the native run loop and WinUSB API to access a USB Bluetooth dongle.

Access to Bluetooth USB Dongle with Zadig

To allow libusb or WinUSB to access an USB Bluetooth dongle, you need to install a special device driver to make it accessible to user space processes.

It works like this:

  • Download Zadig
  • Start Zadig
  • Select Options -> “List all devices”
  • Select USB Bluetooth dongle in the big pull down list
  • Select WinUSB (libusb) in the right pull pull down list
  • Select “Replace Driver”

Toolchain

The port requires a Unix-like toolchain. We successfully used mingw-w64 to compile and run the examples. mingw64-w64 is based on MinGW, which '...provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs.'

We've used the Msys2 package available from the downloads page on Windows 10, 64-bit and use the MSYS2 MinGW 32-bit start menu item to compile 32-bit binaries that run on both 32/64-bit systems.

In the MSYS2 shell, you can install git, python, and, winpty with pacman:

$ pacman -S git
$ pacman -S python
$ pacman -S winpty

Compilation

With mingw64-w64 installed, just go to the port/windows-winusb directory and run make

$ cd btstack/port/windows-winusb
$ make

Console Output

When running the examples in the MSYS2 shell, the console input (via btstack_stdin_support) doesn't work. It works in the older MSYS and also the regular CMD.exe environment. Another option is to install WinPTY and then start the example via WinPTY like this:

$ winpty ./spp_and_le_counter.exe
