1*34fd36daSMatthias 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 203c7822d8SMatthias 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](https://en.wikipedia.org/wiki/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.' 213cda7aedSMatthias Ringwald 22b5674ee2SMatthias 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 64-bit start menu item to compile 64-bit binaries. 233cda7aedSMatthias Ringwald 24b5674ee2SMatthias RingwaldIn the MSYS2 shell, you can install everything with pacman: 253cda7aedSMatthias Ringwald 263cda7aedSMatthias Ringwald $ pacman -S git 27b5674ee2SMatthias Ringwald $ pacman -S make 28b5674ee2SMatthias Ringwald $ pacman -S mingw-w64-x86_64-toolchain 293cda7aedSMatthias Ringwald $ pacman -S python 305b53c16eSMatthias Ringwald $ pacman -S winpty 313cda7aedSMatthias Ringwald 323cda7aedSMatthias Ringwald## Compilation 333cda7aedSMatthias Ringwald 345b53c16eSMatthias RingwaldWith mingw64-w64 installed, just go to the port/windows-winusb directory and run make 353cda7aedSMatthias Ringwald 363cda7aedSMatthias Ringwald $ cd btstack/port/windows-winusb 373cda7aedSMatthias Ringwald $ make 383cda7aedSMatthias Ringwald 390af1bfd9SMatthias RingwaldNote: When compiling with msys2-32 bit and/or the 32-bit toolchain, compilation fails 400af1bfd9SMatthias Ringwaldas `conio.h` seems to be mission. Please use msys2-64 bit with the 64-bit toolchain for now. 410af1bfd9SMatthias Ringwald 423cda7aedSMatthias Ringwald## Console Output 433cda7aedSMatthias Ringwald 44a1a1af71SMatthias 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: 45a1a1af71SMatthias Ringwald 463cda7aedSMatthias Ringwald $ winpty ./spp_and_le_counter.exe 47a1a1af71SMatthias Ringwald 48
