A little bit of research into Sam’s answer that I thought I’d share You can do so without utilizing private API, but with a few caveats: It will only work on iOS 5.0+ It will only work on devices that support the bluetooth LE spec (iPhone 4S+, 5th Generation iPod+, iPad 3rd Generation+) Simply allocating … Read more
No, this is not a bug. This issue was brought up to Google where they responded saying that this was the intended behavior and they won’t fix it. They directed developers to this site where it points out that location permission is now needed for hardware identifier access. It is now the developer’s responsibility to … Read more
Try this… Run gatttool -b <MAC Address> –interactive like you did before. You’ll get a prompt and then you type connect. You should see a CON in the prompt indicating that you’ve connected to the device. Then type char-read-uuid 2902. You should get a list of all CCC (Client Characteristic Configuration) attributes on the device. … Read more
This guide looks promising for Bluetooth 3.0. Remember that the CoreBluetooth framework is ONLY for Bluetooth Low Energy (4.0). At bluetooth.com’s dev-pages you can see some examples of globally defined services, and as Guan Yang mentionen, you can see that the heart rate service is 0x180D. UUID`s of the unit is defined by the manufacturer. … 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

Both need to be done for scanning to work properly. To request the location permission put the following in a dialog or the … Read more
Try to change your code for creating RfcommSocket: sock = zee.createRfcommSocketToServiceRecord( UUID.fromString(“8e1f0cf7-508f-4875-b62c-fbb67fd34812”)); for this code: Method m = zee.getClass().getMethod(“createRfcommSocket”, new Class[] { int.class }); sock = (BluetoothSocket) m.invoke(device, 1); Also try to change argument value in range 1-3 in this m.invoke(device, 1); When connection will be Connected, but aborted when you try reading, call in … Read more
Important implementation hints (Perhaps some of those hints aren’t necessary anymore due to Android OS updates.) Some devices like Nexus 4 with Android 4.3 take 45+ seconds to connect using an existing gatt instance. Work around: Always close gatt instances on disconnect and create a fresh instance of gatt on each connect. Don’t forget to … Read more
This question has been asked many times on this site and the definitive answer is: NO, you can’t connect an Android phone to an iPhone over Bluetooth, and YES Apple has restrictions that prevent this. Some possible alternatives: Bonjour over WiFi, as you mentioned. However, I couldn’t find a comprehensive tutorial for it. Some internet … Read more
I’ve been looking into this as well. You need to include the bluetoothmanager framework and header file in your project. It should be in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/System/Library/PrivateFrameworks/BluetoothManager.framework/ If the header file is not there, you’ll need to grab a .h file that was generated from the library and include it in your project. I googled to find … Read more
