A React Native Bluetooth Low Energy library.

Introduction

The library is a simple connection with the OS APIs, the BLE stack should be standard but often has different behaviors based on the device used, the operating system and the BLE chip it connects to. Before opening an issue verify that the problem is really the library.

Example

The easiest way to test is simple make your AppRegistry point to our example component, like this:

// in your index.ios.js or index.android.js
import React, { Component } from "react";
import { AppRegistry } from "react-native";
import App from "react-native-ble-manager/example/App"; //<-- simply point to the example js!
/* 
Note: The react-native-ble-manager/example directory is only included when cloning the repo, the above import will not work 
if trying to import react-native-ble-manager/example from node_modules
*/
AppRegistry.registerComponent("MyAwesomeApp", () => App);

Or, use the example directly

Library development

from the root folder:

npm install
npm run build

if you are modifying the typescript files of the library (in src/) on the fly, you can run npm run watch instead. If you are modifying files from the native counterparts, you'll need to rebuild the whole app for your target environnement (npm run android/ios).
