1c7558746SMatthias Ringwald# BTstack port for Windows Systems using the WinUSB Driver 2a1a1af71SMatthias Ringwald 3c7558746SMatthias RingwaldThe Windows-WinUSB port uses the native run loop and WinUSB API to access a USB Bluetooth dongle. 4a1a1af71SMatthias Ringwald 53cda7aedSMatthias Ringwald## Access to Bluetooth USB Dongle with Zadig 63cda7aedSMatthias Ringwald 7a1a1af71SMatthias RingwaldTo 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. 8a1a1af71SMatthias Ringwald 9a1a1af71SMatthias RingwaldIt works like this: 103cda7aedSMatthias Ringwald 11c7558746SMatthias Ringwald- Download [Zadig](http://zadig.akeo.ie) 12c7558746SMatthias Ringwald- Start Zadig 13a1a1af71SMatthias Ringwald- Select Options -> “List all devices” 14a1a1af71SMatthias Ringwald- Select USB Bluetooth dongle in the big pull down list 15a1a1af71SMatthias Ringwald- Select WinUSB (libusb) in the right pull pull down list 16a1a1af71SMatthias Ringwald- Select “Replace Driver” 17a1a1af71SMatthias Ringwald 183cda7aedSMatthias Ringwald## Toolchain 193cda7aedSMatthias Ringwald 20*5b53c16eSMatthias RingwaldThe 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.' 213cda7aedSMatthias Ringwald 22*5b53c16eSMatthias RingwaldWe'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 32-bit start menu item to compile 32-bit binaries that run on both 32/64-bit systems. 233cda7aedSMatthias Ringwald 24*5b53c16eSMatthias RingwaldIn the MSYS2 shell, you can install git, python, and, winpty with pacman: 253cda7aedSMatthias Ringwald 263cda7aedSMatthias Ringwald $ pacman -S git 273cda7aedSMatthias Ringwald $ pacman -S python 28*5b53c16eSMatthias Ringwald $ pacman -S winpty 293cda7aedSMatthias Ringwald 303cda7aedSMatthias Ringwald## Compilation 313cda7aedSMatthias Ringwald 32*5b53c16eSMatthias RingwaldWith mingw64-w64 installed, just go to the port/windows-winusb directory and run make 333cda7aedSMatthias Ringwald 343cda7aedSMatthias Ringwald $ cd btstack/port/windows-winusb 353cda7aedSMatthias Ringwald $ make 363cda7aedSMatthias Ringwald 373cda7aedSMatthias Ringwald## Console Output 383cda7aedSMatthias Ringwald 39a1a1af71SMatthias RingwaldWhen 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: 40a1a1af71SMatthias Ringwald 413cda7aedSMatthias Ringwald $ winpty ./spp_and_le_counter.exe 42a1a1af71SMatthias Ringwald 43
