Bluetooth HCI socket binding for Node.js
NOTE: Currently only supports Linux and Windows.
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.
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
Name | USB VID | USB PID |

npm install bluetooth-hci-socket
var BluetoothHciSocket = require('bluetooth-hci-socket');
var bluetoothHciSocket = new BluetoothHciSocket();
var filter = new Buffer(14);
// ...
bluetoothHciSocket.setFilter(filter);
bluetoothHciSocket.bindRaw([deviceId]); // optional deviceId (integer)
bluetoothHciSocket.bindUser([deviceId]); // optional deviceId (integer)
Requires the device to be in the powered down state (sudo hciconfig hciX down
).
bluetoothHciSocket.bindControl();
Query the device state.
var isDevUp = bluetoothHciSocket.isDevUp(); // returns: true or false
Note: must be called after bindRaw
.
Start or stop event handling:
bluetoothHciSocket.start();
// ...
bluetoothHciSocket.stop();
Note: must be called after bindRaw
or bindControl
.
var data = new Buffer(/* ... */);
// ...
bluetoothHciSocket.write(data);
Note: must be called after bindRaw
or bindControl
.
bluetoothHciSocket.on('data', function(data) {
// data is a Buffer
// ...
});
bluetoothHciSocket.on('error', function(error) {
// error is a Error
// ...
});
See examples folder for code examples.
Unload btusb
