To Enable the Bluetooth you could use either of the following functions: public void enableBT(View view){ BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (!mBluetoothAdapter.isEnabled()){ Intent intentBtEnabled = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); // The REQUEST_ENABLE_BT constant passed to startActivityForResult() is a locally defined integer (which must be greater than 0), that the system passes back to you in your onActivityResult() // implementation as the requestCode parameter. int REQUEST_ENABLE_BT = 1; startActivityForResult(intentBtEnabled, REQUEST_ENABLE_BT); } }The second function is:public void enableBT(View view){ BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); if (!mBluetoothAdapter.isEnabled()){ mBluetoothAdapter.enable(); }}The difference is that the first function makes the app ask the user a permission to turn on the Bluetooth or to deny.
