I am an student developing an android application that will need to access the Bluetooth connection/disconnection.
I am new to android but I'm studying hard to be more familiar in creating android application.
please can anyone help me how to check if Bluetooth device is connected or not?
and also i want to detect if device is suddenly disconnected.
Please see these docs:
http://developer.android.com/guide/topics/connectivity/bluetooth.html
Specifically you're looking for:
Querying Paired Devices
and
Discovering devices
Also see this question:
How to programmatically tell if a Bluetooth device is connected? (Android 2.2)

I want to implement Bluetooth HID device role in An android based system.It has KitKat in it.. By default Android Kitkat has support for HID Host role... But I am unable to get an idea about how to implement the device role..
I have seen this video link
http://hsc.com/Blog/Android-Labs-Bluetooth-HID-device-implementation-your-phone-as-a-mouse-voice-control
here they said that they had changed a little in framework and classic Bluetooth application ...they had also used one flag....
I am new to Android environment. Can anyone help me...???
You have to change Bluetooth stack and build a customized ROM. The work is not simple.
I want to connect a 3rd party bluetooth device to my Android Wear watch (Samsung Gear Live). I am trying to find documentation on how to do this but I am not having any luck. All the searches I do seem to think I want to attach to a phone.
Does anyone know of a good example that shows how to connect, for example, a bluetooth heart rate monitor (or other device) to the Android Wear so I can keep a history when the phone isn't present? Is this even possible? Would it be the same protocols as doing it from a phone/tablet?
#Ryan Tensmeyer, I think #Wayne Pieksarki's answer is now out-dated. I was able to create and run a stand-alone app that used BLE to connect to a third-party bluetooth device, namely, a wireless thermometer. I used a library called SweetBlue and tested the stand-alone app on an Android Wear Moto 360. It worked great -- no phone required!
It is not possible to connect 3rd party bluetooth devices to an Android Wear watch as you describe. You will need to pair your heart rate monitor with your phone, extract the data you want, and then use the Data Layer API to send the data to the wearable for display to the user.
EDIT: Android Wear devices now support the ability to pair with Bluetooth devices.
I want to connect two android phones via Bluetooth low energy but, I dont know how to create characteristic uuids and service uuid in android; I Googled a lot that I could connect the two android phones via Bluetooth low energy but, could not find useful stuff.
Please guide me that how could I solve the issue. I would be very thankful for this act of kindness. Thanks in advance.
From what i understood:
Upload BluetoothChat sample codes to both devices using Eclipse or Android studio
Pair them
Open BluetoothChat sample app
Connect to each other
Bingo, you are connected and even can chat in a range.

Can a program that is written using the gingerbread/froyo/eclair (e.g. 2.1, 2.2, 2.3 -> NOT honeycomb) connect to a A2DP bluetooth sink device?? Or, do I need to have the user go to their settings to do so? Any help or advice would be highly appreciated.
So, after much more research, it seems that it is impossible to programmatically connect to a A2DP device on a pre-3.0 Android device. I am going mark this as the answer but, if someone finds otherwise, please correct me on this as I would really like to do it programmatically.
Can't you use BluetoothA2dp::connectSink()? Create a BluetoothA2dp instance, then call connectSink(BluetoothDevice device) with the device you're trying to connect to.
code:
http://www.google.com/codesearch#uX1GffpyOZk/core/java/android/bluetooth/BluetoothA2dp.java&q=BluetoothA2dp&l=112
It seems like this API is not listed in the Android API reference for BluetoothA2dp though:
http://developer.android.com/reference/android/bluetooth/BluetoothA2dp.html
So, after much more research, I found and verified that it is actually possible to use the hidden API's to connect to a a2dp device via bluetooth. However, it seems that post-honeycomb, that method isn't possible anymore... I will post another question regarding that.
I have a problem in pairing the android Device (Desire) with any other Device (e.g Nokia) through Bluetooth, and i am using the Application the (Bluetooth-Chat) provided in the samples of the SDK 2.2, the behavior of the Application is that it shows all the devices having bluetooth switched on, and also paired it but only android devices, so how can i connect the android device with any other device (e.g Nokia), what are the limitations, what needs to be change in the Code, i tried to debug the Code and find out where the problem exists but i do not found any reason.
So kindly help me in this regard, i will be very thankful to you.
