Installation

To install buttplug-js in your node project via npm, a simple add call should do it.

npm add buttplug-node-bluetoothle-manager

Usage Example

This module provides a DeviceManager derived class that can be added to a Buttplug server. Not that this manager will not work with browser-based projects, it is only meant for native node projects. Browser-based projects can use the WebBluetooth manager that comes as part of buttplug-js.

To add a new BluetoothLE manager:

let Buttplug = require('buttplug');
let ButtplugBLEManager = require('buttplug-bluetoothle-manager');
let bs = new Buttplug.ButtplugServer();
bs.AddDeviceManager(new ButtplugBLEManager.ButtplugBluetoothLEDeviceManager());
// ...

After the manager has been added, if the server receives a StartScanning request and has a bluetooth radio that is connected and on, it will scan for bluetooth devices. The server can find all devices supported by the version of buttplug-js in your project. See the buttplug-js README for a list of supported devices.

Running Without Root or Sudo on Linux

To connect to bluetooth without having to use sudo or root on Linux, run the following command:

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

This grants the node binary cap_net_raw privileges, so it can start/stop BLE advertising.

Note: The above command requires setcap to be installed, it can be installed using the following:

• apt: sudo apt-get install libcap2-bin
• yum: su -c \'yum install libcap2-bin\'
