自動安卓發布了4.0版本的藍牙協議之后，越來越多的開發者收到了各種針對於BLE藍牙的開發需求。
而且有很多時候還需要兼容以前的3.0版本，給大家的開發帶來了困擾，筆者也遇到了這樣的問題，偶然間發現了getType()這個函數的妙用。
public int getType () Added in API level 18
Get the Bluetooth device type of the remote device.
Returns the device type DEVICE_TYPE_CLASSIC, DEVICE_TYPE_LE DEVICE_TYPE_DUAL. DEVICE_TYPE_UNKNOWN if it’s not available
public static final int DEVICE_TYPE_CLASSIC Added in API level 18
Bluetooth device type, Classic – BR/EDR devices Constant Value: 1 (0x00000001)
public static final int DEVICE_TYPE_DUAL Added in API level 18
Bluetooth device type, Dual Mode – BR/EDR/LE Constant Value: 3 (0x00000003)
public static final int DEVICE_TYPE_LE Added in API level 18
Bluetooth device type, Low Energy – LE-only Constant Value: 2 (0x00000002)
public static final int DEVICE_TYPE_UNKNOWN Added in API level 18
Bluetooth device type, Unknown Constant Value: 0 (0x00000000)
跟據這個接口，你可以方便的定義一個函數用來分辨搜索到的藍牙設備的版本。如

public static String deviceTypeTyString(int paramInt) {
switch (paramInt) {
default:
return "UNKNOWN";
case 1:
return "CLASSIC";
case 3:
return "CLASSIC and BLE";
case 2:
}
return "BLE only";
}
public static boolean isBLEDevice( BluetoothDevice device ) {
return (device.getType() == 2);
}
