Bleno MacOS bindings using the official CoreBluetooth API

Bleno (Node.js Bluetooth LE) for MacOS

The mac bindings in the bleno repository use a XPC connection and an undocumented protocol to communicate directly with the bluetooth daemon. This is error prone, as the protocol needs to be reverse engineered by sniffing the communication between a regular program which uses the official CoreBluetooth API and the bluetooth daemon. Since the protocol is not public Apple can change it at anytime (For now every new OSX release changed the protocol).

This package provides the same functionality as the regular bleno mac bindings using the official CoreBluetooth API.

System Requirements

• Node.js v6.14.2 or later.
• macOS 10.7 or later

Prerequisites

OS X

• install Xcode

Usage

Simply require bleno-mac instead of bleno:

const bleno = require('bleno-mac');

On non-Mac platforms this will use the regular bleno implementation and on MacOS it will use the native binding using the official CoreBluetooth API.

Note

Be careful to not write to the Client Characteristic Configuration descriptor directly to enable notification. Use subscribe instead to enable and listen to notifications.

Implementation Status

Everything should work that also works with the regular bleno mac bindings.
