在Tizen可穿戴设备上获取蓝牙状态

Question

I'm creating a watch face for my Gear 2 Neo (using Tizen Wearable SDK ), and I've spent hours looking (with no luck) for a way to determine if the bluetooth is enabled or not (and if possible if it's connected).

I've tried looking at the Tizen.SystemInfo API documents, but I can't find anything. I've even tried tizen.systeminfo.getPropertyValue(); with "BLUETOOTH" / "NETWORK" as the property name, but this doesn't work. It seems the Tizen.Bluetooth namespace isn't usable either.

I know there must be a way, as I have seen several watch faces out there that are able to get the status.

Is anyone able to help me out / point me in the right direction?

Edit:

Using tizen.bluetooth.getDefaultAdapter(); returns the following: "The application does not have the privilege to call this method"

Yes, it is possible.

To get the bluetooth status, you need to first get the defaultAdapter using following API

var blueAdapter = tizen.bluetooth.getDefaultAdapter();
console.log(blueAdapter); // To log the object
       /* Output of above log
          BluetoothAdapter
          address: ""
          name: ""
          powered: false
          visible: true
       */

if (blueAdapter.powered) {
    // Bluetooth is on, you can off using
    blueAdapter.setPowered(false);
} else {
    // Bluetooth is off, you can switch on using
    blueAdapter.setPowered(true);
}

Don't forget to add the privilege in config.xml of your app.

<tizen:privilege name="http://tizen.org/privilege/bluetooth.gap"/>

Note: Whenever you try to use platform, you need to provide the corresponding privilege in your apps config.xml file
