node-bluetooth-hci-socket
Bluetooth HCI socket binding for Node.js
NOTE: Currently only supports Linux and Windows.
Prerequisites
Linux
- Bluetooth 4.0 Adapter
Note: the node-usb dependency might fail install, this is ok, because it is an optional optional dependency. Installing libudev-dev
via your Linux distribution's package manager will resolve the problem.
Windows
This library needs raw USB access to a Bluetooth 4.0 USB adapter, as it needs to bypass the Windows Bluetooth stack.
A WinUSB driver is required, use Zadig tool to replace the driver for your adapter.
WARNING: This will make the adapter unavailable in Windows Bluetooth settings! To roll back to the original driver go to: Device Manager -> Open Device -> Update Driver
