Yes, I found a working solution for running Bluetooth background in Android. Below is the code I have used in my android app. public class BluetoothServices extends Service { private BluetoothAdapter mBluetoothAdapter; public static final String B_DEVICE = “MY DEVICE”; public static final String B_UUID = “00001101-0000-1000-8000-00805f9b34fb”; // 00000000-0000-1000-8000-00805f9b34fb public static final int STATE_NONE = … Read more
Add a broadcast listener to MEDIA_BUTTON: <intent-filter android:priority=”<some number>”> <action android:name=”android.intent.action.MEDIA_BUTTON” /> </intent-filter> You should register your broadcast receiver inside your application (not in manifest file). Otherwise Google Music player will catch your broadcast and aboard it. Your IntentFilter priority should be higher that other media players priorities in your phone) Add android.permission.BLUETOOTH permission in … Read more
I’ve already gone through this for at least one week having this same issue. I’ve already asked a question here and I’ve already answered on my own. The main problem is an Android BUG issue. It’s sending a non permitted command on a fixed L2CAP channnel. But when Android is communicating with normal peripheral BLE … Read more
YES This is possible on Android 5+, and you can find open-source code for transmitting as a beacon in the Android Beacon Library. There is also a full-featured version of a beacon transmitter in the Beacon Scope app in the Google Play Store. Here’s an example of transmitting iBeacon with the Android Beacon Library: Beacon … Read more
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
How can I avoid or dismiss Android’s Bluetooth pairing notification when I am doing programmatic pairing? This seems to give you the answer, with the pin entering and all. It involves sending .setPin() whenever you get the message.
So, here’s all I found after reading blogs, threads, documentations, SO answers etc. regarding Android’s bluetooth discovery. Thought this might be useful to post my findings here. So before someone starts reading, I want to clarify that, I could not find any way to detect a bluetooth device nearby which is turned on but not … Read more
The txPower mentioned by @davidgyoung is given by the formula: RSSI = -10 n log d + A where d = distance A = txPower n = signal propagation constant RSSI = dBm In free space n = 2, but it will vary based on local geometry – for example, a wall will reduce RSSI … Read more
In order to catch Bluetooth state changes (STATE_OFF, STATE_TURNING_ON, STATE_ON, STATE_TURNING_OFF), do this: First, add Bluetooth permission to your AndroidManifest file: <uses-permission android:name=”android.permission.BLUETOOTH” /> Create a BroadcastReceiver in your Activity or Service: private final BroadcastReceiver mBroadcastReceiver1 = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { final String action = intent.getAction(); if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) … 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
