2. Turn OFF click (to turn off the Bluetooth and to check if the button is working)
3. Turn ON click (turn on the Bluetooth again)

By requiring location services to access Bluetooth, you ensure that the user understands their location information may leak when they use Bluetooth. In versions of Android prior to Marshmallow, the user could use Bluetooth without location services enabled, but location information could leak.

You must request the BLUETOOTH permission in order to perform any Bluetooth communication, such as requesting a connection, accepting a connection, and transferring data. You must request the BLUETOOTH_ADMIN permission in order to initiate device discovery or manipulate Bluetooth settings.

Yes, Bluetooth can be hacked. While using this technology has offered a lot of creature comforts, it has also exposed people to cyberattacks. Almost all devices are Bluetooth enabled—from smartphones to cars.

When we click on Turn ON or Turn OFF buttons, we can make the device Bluetooth turn ON or OFF and then click on Discoverable button, our device discoverable to other Bluetooth devices. This is how we can make our device discoverable to other nearby Bluetooth devices in android applications based on our requirements.

Step 2: Connect

1. Swipe down from the top of the screen.
2. Make sure Bluetooth is turned on.
3. Touch and hold Bluetooth .
4. In the list of paired devices, tap a paired but unconnected device.
5. When your phone and the Bluetooth device are connected, the device shows as “Connected.”

Android application to check Bluetooth status ON/OFF & turn ON/OFF by using android app

1. Create a new project in android studio.
2. Add following code on activity_main.xml.
3. Add following code on MainActivity.java. import android.bluetooth.BluetoothAdapter;
4. Add following code in AndroidManifest.xml file above element.

Bluetooth technology offers convenience – from hands-free phone calls to wireless file-sharing to playing music on a vehicle’s speakers. But leaving your Bluetooth on all the time can be dangerous, and hackers are exploiting the technology to access private information, spread malicious software and more.

To run the app from Android studio, open one of your project’s activity files and click Run icon from the tool bar.If your Bluetooth will not be turned on then, it will ask your permission to enable the Bluetooth. Now just select the Get Visible button to turn on your visibility.

For most recent versions of Android, your device will be become visibleto nearby Bluetooth devices as soon as you enter the Bluetooth settings menu. Older devices may require you to toggle Bluetooth visibility manually, using an option called My deviceor Visible/ Not visible.

According to Android documentation, the maximum time for being discoverable is capped at 300seconds. You cannot make the BT discoverable forever. Please see: http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#ACTION_REQUEST_DISCOVERABLE In order to get the 300second maximum period, you need to change one line of code as:

(* The user can usually set the visibility to ‘No Time Out’, but that requires the user to set that option directly under Bluetooth Settings of their smartphone, which is not a very elegant solution…) I come to the same conclusion on three devices I have.
