btstack/port/windows-winusb-intel

BTstack Port for Windows Systems with Intel Wireless 8260/8265 Controllers

Same as port/windows-winusb, but customized for Intel Wireless 8260 and 8265 Controllers. These controller require firmware upload and configuration to work. Firmware and config is downloaded from the Linux firmware repository.

The port provides both a regular Makefile as well as a CMake build file. It uses native Win32 APIs for file access and does not require the Cygwin or mingw64 build/runtine. All examples can also be build with Visual Studio 2022 (e.g. Community Edition).

Access to Bluetooth USB Dongle with Zadig

To allow 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 in the right pull down list
• Select “Replace Driver”

After the new driver was installed, your device is shown in the Device Manager with Device Provider 'libwdi'

Visual Studio 2022

Visual Studio can directly open the provided port/windows-winusb-intel/CMakeLists.txt and allows to compile and run all examples.

mingw64

It can also be compiles with a regular Unix-style toolchain like mingw-w64. 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.'

In the MSYS2 shell, you can install everything with pacman:

$ pacman -S git
$ pacman -S cmake
$ pacman -S make
$ pacman -S mingw-w64-x86_64-toolchain
$ pacman -S mingw-w64-x86_64-portaudio
$ pacman -S python
$ pacman -S winpty

Compilation with CMake

With mingw64-w64 installed, just go to the port/windows-h4 directory and use CMake as usual

$ cd port/windows-h4
$ mkdir build
$ cd build
$ cmake ..
$ make

Note: When compiling with msys2-32 bit and/or the 32-bit toolchain, compilation fails as conio.h seems to be mission. Please use msys2-64 bit with the 64-bit toolchain for now.

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 ./gatt_counter.exe

The packet log will be written to hci_dump.pklg
