Hi aca-mobile,
I have tried to implement code for android device with new version of this library. didDiscoverPeripheral find my peripheral (in my sample UART Service);
didConnectPeripheral run correctly;
didUpdateValueForCharacteristic don't run correctly:
This is my log:

And this is my sample code:

var CHARACTERISTIC_UUID_TX = '6E400003-B5A3-F393-E0A9-E50E24DCCA9E';
var win = Ti.UI.createWindow({
backgroundColor : '#fff'
});
var btn1 = Ti.UI.createButton({
title : 'Start scan',
top : 40
});
btn1.addEventListener('click', function() {
if (centralManager.isScanning()) {
alert('Already scanning, please stop scan first!');
return;
} else if (centralManager.getState() != BLE.MANAGER_STATE_POWERED_ON) {
alert('The BLE manager needs to be powered on before. Call initialize().');
return;
}
centralManager.startScan();
});
var btn2 = Ti.UI.createButton({
title : 'Stop scan',
top : 100
});
btn2.addEventListener('click', function() {
if (!centralManager.isScanning()) {
alert('Not scanning!');
return;
}
centralManager.stopScan();
});

Whats's wrong in my code?
The same code in IOS work fine!
