According to this interesting site : http://code.google.com/p/btstack/wiki/iPhoneBluetooth Apple are using a special chip besides their Bluetooth RF chip which denies any connection for a device without that chip – this means its a lock on the hardware level.
100% working solution : no need any 3rd party plugin manifest code: <!–BLUETOOTH PERMISSION–> <!– Request legacy Bluetooth permissions on older devices. –> <uses-permission android:name=”android.permission.BLUETOOTH” /> <uses-permission android:name=”android.permission.BLUETOOTH_ADMIN” /> <!– Needed only if your app looks for Bluetooth devices. If your app doesn’t use Bluetooth scan results to derive physical location information, you can strongly … Read more

The workaround is to ditch CoreLocation framework altogether and create your own proximity “framework” using only CoreBlueTooth. You still need to use the appropriate background specifiers in the Info.plist file (e.g. bluetooth-peripheral and bluetooth-central). … Read more
It seems like you forgot to write the Descriptor which tells your BLE device to go in this mode. See the code lines that deal with descriptor at http://developer.android.com/guide/topics/connectivity/bluetooth-le.html#notification Without setting this descriptor, you never receive updates to a characteristic.

You will want to register a BroadcastReceiver to listen for any changes in the state of the BluetoothAdapter: As a private instance variable in your Activity (or in a separate class file… whichever one you prefer): private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { final String action … Read more
I would try CoolTerm and see if that works for you. I was having a similar issue connecting a speaker with a Sigma DSP chip inside via USB connection, so if you are having trouble seeing external devices it may be that the device is incompatible with your computer. Download CoolTerm and go to options … Read more
Could you please try below. I did not try myself but sounds similar problem if I understand correctly: Android Bluetooth Earpiece Volume “Android is using int 6 for bluetooth volume and not documented. Just use 6 instead of AudioManager.STREAM_VOICE_CALL and try, It should work“ I assume for you will be to replace AudioManager.STREAM_BLUETOOTH_SCO with 6. … Read more
Android 4.4 (Kit Kat) does have a new sniffing capability for Bluetooth. You should give it a try. If you don’t own a sniffing device however, you aren’t necessarily out of luck. In many cases we can obtain positive results with a new feature introduced in Android 4.4: the ability to capture all Bluetooth HCI … Read more
There you go: BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (mBluetoothAdapter == null) { // Device does not support Bluetooth } else if (!mBluetoothAdapter.isEnabled()) { // Bluetooth is not enabled 🙂 } else { // Bluetooth is enabled } With uses-permission <uses-permission android:name=”android.permission.BLUETOOTH” android:required=”false” />
