# 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](http://zadig.akeo.ie)
|
|
- 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](https://mingw-w64.org/doku.php) to compile and run the examples. mingw64-w64 is based on [MinGW](mingw.org), 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](https://mingw-w64.org/doku.php/download) on Windows 10, 64-bit and use the MSYS2 MinGW 64-bit start menu item to compile 64-bit binaries.
|
|
|
|
In the MSYS2 shell, you can install everything with pacman:
|
|
|
|
$ pacman -S git
|
|
$ pacman -S make
|
|
$ pacman -S mingw-w64-x86_64-toolchain
|
|
$ 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
|
|
