BTstack Port for POSIX Systems with libusb library

The quickest way to try BTstack is on a Linux or OS X system with an additional USB Bluetooth dongle. It requires pkg-config and libusb-1.0 or higher to be installed.

On Linux, the USB Bluetooth donle is usually not accessible to a regular user. You can:

• run the examples as root
• add a udev rule for your dongle to extend access rights to user processes

To add an udev rule, please create /etc/udev/rules.d/btstack.rules and add this

# Match all devices from CSR
SUBSYSTEM=="usb", ATTRS{idVendor}=="0a12", MODE="0666"

# Match DeLOCK Bluetooth 4.0 dongle
SUBSYSTEM=="usb", ATTRS{idVendor}=="0a5c", ATTRS{device}=="21e8", MODE="0666"

# Match Asus BT400
SUBSYSTEM=="usb", ATTRS{idVendor}=="0b05", ATTRS{device}=="17cb", MODE="0666"

On OS X, it’s necessary to tell the OS to only use the internal Bluetooth. For this, execute:

sudo nvram bluetoothHostControllerSwitchBehavior=never

and then reboot to activate the change.
