Example how to setup

I am struggling to implement the following

• central manager finds peripherals
• I connect to the peripheral I want

  [INFO] :   didDiscoverServices
  [INFO] :   {
  [INFO] :       bubbles = 1;
  [INFO] :       cancelBubble = 0;
  [INFO] :       error = "<null>";
  [INFO] :       peripheral = "[object TiBluetoothPeripheral]";
  [INFO] :       source = "[object TiBluetoothPeripheral]";
  [INFO] :       type = didDiscoverServices;
  [INFO] :   }
  [INFO] :   [object TiBluetoothPeripheral]
  [INFO] :   (
  [INFO] :       "[object TiBluetoothService]",
  [INFO] :       "[object TiBluetoothService]"
  [INFO] :   )
  [INFO] :   peripheral has  2 service(s)
  [INFO] :   service characteristics  <null>
  [INFO] :   service characteristics  <null>

Next I want to get the UUIDs from the services, and subscribe to let's say one of them My code so far:

    centralManager.addEventListener('didConnectPeripheral', function(e) {
        console.log('\ndidConnectPeripheral');
        console.log(e);
        console.log(e.peripheral);

        centralManager.stopScan();
        connectedPeripheral = e.peripheral;

        connectedPeripheral.addEventListener('didDiscoverServices', function(e) {
            console.log('\ndidDiscoverServices');
            console.log(e);
            console.log(e.peripheral);
            console.log(e.peripheral.services);

            console.log('peripheral has ', e.peripheral.services.length, 'service(s)');
            var services = e.peripheral.services;

            for (var i = 0; i < services.length; i++)
                console.log('service characteristics ', services[i].characteristics.uuid);
            // if (service.UUID.toLowerCase() == CUSTOM_SERVICE_UUID.toLowerCase()) {
            // e.peripheral.discoverCharacteristicsForService(service);
            // }
        });

        connectedPeripheral.addEventListener('didDiscoverCharacteristicsForService', function(e) {
            console.log('didDiscoverCharacteristicsForService');
            console.log(e);
        });

        connectedPeripheral.addEventListener('didUpdateValueForCharacteristic', function(e) {
            console.log('didUpdateValueForCharacteristic');
            console.log(e);
        });

        connectedPeripheral.discoverServices();
    });

You have to add the event listener on the latest peripheral you get

centralManager.addEventListener('didConnectPeripheral', function(e) {
    console.log('\ndidConnectPeripheral');
    console.log(e);
    console.log(e.peripheral);

    centralManager.stopScan();
    connectedPeripheral = e.peripheral;

    connectedPeripheral.addEventListener('didDiscoverServices', function(e) {
        console.log('\ndidDiscoverServices');
        console.log(e);
        console.log(e.peripheral);
        console.log(e.peripheral.services);

        var peripheral = e.peripheral;

        peripheral.addEventListener('didDiscoverCharacteristicsForService', function(e) {
            console.log('didDiscoverCharacteristicsForService');
            console.log(e);
        });

        peripheral.services.forEach(function(service) {
            peripheral.discoverCharacteristicsForService({ service: service });
        });
    });

    connectedPeripheral.discoverServices();
});

I am doing that, please take a look at https://github.com/hansemannn/titanium-bluetooth/issues/23

I updated that issue today.
