react-native-obd2

React-native OBD-II reader designed to connect with Bluetooth Elm327 OBD reader. This project is inspired from android-obd-reader so that we wrapped the OBD Java API in order to use in react-native world.

How to install

Run below link on your project root folder.
```
$ npm install react-native-obd2 --save
$ react-native link
``

APIs

ready()

This method will check a bluetooth status and prepare to use it.
``
const obd2 = require('react-native-obd2');
...
obd2.ready();
``

getBluetoothDeviceNameList

This method brings available bluetooth device information including name and address. The result is array type of maps which consist of "name" and "address".

$3

``
const obd2 = require('react-native-obd2');
...
obd2.getBluetoothDeviceNameList()
.then((nameList) => console.log('Bluetooth device list : ' + JSON.stringify(nameList)))
.catch((e) => console.log('Get device name error : ' + e)));
``

$3

``
Bluetooth device list: [{name: "OBD-II", address: "10 F0 8B 3F 91"}]
``

setMockUpMode(enabled)

react-native-obd2 provides mock up mode so that you can simply check your apps without connecting real bluetooth device as android-obd-reader did. Default value is 'false'. Therefore, react-native-obd2 will work in real mode if you do not use this method.

startLiveData(btDeviceAddress)

Do work! do!
The data is flow to your listeners. Therfore you have to set your listenr named 'obd2LiveData'.

$3

``
const obd2 = require('react-native-obd2');
...
componentDidMount() {
this.obdLiveDataListener = DeviceEventEmitter.addListener('obd2LiveData', this.obdLiveData);
obd2.startLiveData('10 F0 8B 3F 91');
}

componentWillUnmount() {
this.obdStatusListener.remove();
}
``

stopLiveData()

Hey stop it!

Listeners

$3

for getting bluetooth device status.

JSON key | Type | Description
