version](https://badge.fury.io/js/react-native-bluetooth-escpos-printer.svg)](https://www.npmjs.com/package/react-native-bluetooth-escpos-printer)\r\n\r\n## Installation\r\n### Step 1 ###\r\nInstall via NPM [Check In NPM](https://www.npmjs.com/package/react-native-bluetooth-escpos-printer)\r\n```bash\r\nnpm install @camiloarc/react-native-bluetooth-escpos-printer --save\r\n```\r\n\r\nOr install via github\r\n```bash\r\nnpm install https://github.com/CamiloARC/react-native-bluetooth-escpos-printer.git --save\r\n```\r\n\r\n### Step2 ###\r\nLink the plugin to your RN project\r\n```bash\r\nreact-native link @camiloarc/react-native-bluetooth-escpos-printer\r\n```\r\n\r\n### Manual linking (Android) ###\r\nEnsure your build files match the following requirements:\r\n\r\n1. (React Native 0.59 and lower) Define the *`react-native-bluetooth-escpos-printer`* project in *`android/settings.gradle`*:\r\n\r\n```\r\ninclude ':camiloarc_react-native-bluetooth-escpos-printer'\r\nproject(':camiloarc_react-native-bluetooth-escpos-printer').projectDir = new File(rootProject.projectDir, '../node_modules/@camiloarc/react-native-bluetooth-escpos-printer/android')\r\n```\r\n2.

(React Native 0.59 and lower) Add *`import cn.jystudio.bluetooth.RNBluetoothEscposPrinterPackage;`* and *`new RNBluetoothEscposPrinterPackage()`* in your *`MainApplication.java`* :\r\n\r\n\r\n\r\n### Step3 ###\r\nRefers to your JS files\r\n```javascript\r\n import {BluetoothManager,BluetoothEscposPrinter,BluetoothTscPrinter} from '@camiloarc/react-native-bluetooth-escpos-printer';\r\n```\r\n\r\n## Usage and APIs ##\r\n\r\n### BluetoothManager ###\r\nBluetoothManager is the module for Bluetooth service management, supports Bluetooth status check, enable/disable Bluetooth service, scan devices, connect/unpair devices.\r\n\r\n* isBluetoothEnabled ==>\r\nasync function, checks whether Bluetooth service is enabled.\r\n//TODO: consider to return the the devices information already bound and paired here..\r\n\r\n```javascript\r\n BluetoothManager.isBluetoothEnabled().then((enabled)=> {\r\n alert(enabled) // enabled ==> true /false\r\n }, (err)=> {\r\n alert(err)\r\n });\r\n```\r\n\r\n* enableBluetooth ==> ``` diff + ANDROID ONLY ```\r\nasync function, enables the bluetooth service, returns the devices information already bound and paired. ``` diff - IOS would just resovle with nil ```\r\n\r\n```javascript\r\nBluetoothManager.enableBluetooth().then((r)=>{\r\n var paired = [];\r\n if(r && r.length>0){\r\n for(var i=0;i{\r\n alert(err)\r\n });\r\n```\r\n\r\n* disableBluetooth ==> ``` diff + ANDROID ONLY ```\r\nasync function ,disables the bluetooth service. ``` diff - IOS would just resovle with nil ```\r\n\r\n```javascript\r\nBluetoothManager.disableBluetooth().then(()=>{\r\n // do something.\r\n },(err)=>{alert(err)});\r\n```\r\n\r\n* scanDevices ==>\r\nasync function , scans the bluetooth devices, returns devices found and paired after scan finish. Event [BluetoothManager.EVENT_DEVICE_ALREADY_PAIRED] would be emitted with devices bound; event [BluetoothManager.EVENT_DEVICE_FOUND] would be emitted (many time) as long as new devices found.\r\n\r\nsamples with events:\r\n```javascript\r\n DeviceEventEmitter.addListener(\r\n BluetoothManager.EVENT_DEVICE_ALREADY_PAIRED, (rsp)=> {\r\n this._deviceAlreadPaired(rsp) // rsp.devices
