Determining Bluetooth stack version programatically on an Android device

How do I find the Bluetooth stack version on an Android device programatically?

For example, the w开发者_StackOverfloway to find the Android version is android.os.Build.VERSION.RELEASE. So, is there any similar way to find out the Bluetooth stack version?

int version = Integer.parseInt(Build.VERSION.SDK);
String bluezStack = "";
switch (version) {
    case Build.VERSION_CODES.BASE:
    case Build.VERSION_CODES.BASE_1_1:
    case Build.VERSION_CODES.CUPCAKE:
    case Build.VERSION_CODES.DONUT:
        bluezStack = "Bluez 3.36";
        break;
    case Build.VERSION_CODES.ECLAIR:
    case Build.VERSION_CODES.ECLAIR_0_1:
    case Build.VERSION_CODES.ECLAIR_MR1:
    case Build.VERSION_CODES.FROYO:
        bluezStack = "Bluez 4.47";
        break;
    case Build.VERSION_CODES.GINGERBREAD:
    case Build.VERSION_CODES.GINGERBREAD_MR1:
    case Build.VERSION_CODES.HONEYCOMB:
    case Build.VERSION_CODES.HONEYCOMB_MR1:
    case Build.VERSION_CODES.HONEYCOMB_MR2:
        bluezStack = "Bluez 4.69";
        break;
    default:
        break;
}
