Usage

It follows the noble api usage.

Only support of following usages on iOS !

Require the module

var noble = ('react-native-ble');

Handle Bluetooth State

noble.on('stateChange', function (state) {
  if (state === 'poweredOn') {
    console.log('Start Scanning');
    noble.startScanning([], false);
  } else {
    noble.stopScanning();
    console.log('Stop Scanning');
  }
});

Start Scanning

noble.on('discover', function (peripheral) {
  // Peripheral is an object that was found
});

Peripheral

Connect

peripheral.connect(function (error) {

});

Disconnect

When you're connected to a peripheral, you can handle the automatic disconnection by doing :

peripheral.once('disconnect', function () {

});

If you want to disconnect manually :
```javascript
peripheral.disconnect(function (error) {

});

Discover Services

var serviceUUIDs = ["<service UUID 1>", ...];
peripheral.discoverServices(serviceUUIDs, function (error, services) {

});

Service

Discover characteristics

var service = services[0];
var characteristicsUUIDs = ["<service UUID 1>", ...];
service.discoverCharacteristics(characteristicsUUIDs, function (characteristics) {

});

Characteristic

Read

var characteristic = characteristics[0];
characteristic.read(function (data) {
  // Data is a buffer
});

Notify

var characteristic = characteristics[0];
characteristic.notify(function (data) {
  // Data is a buffer
});
