How to turn on Bluetooth from inside Unity?

Question

Hi,

I am looking for a way to turn on Bluetooth on Android and iOS devices from inside my unity application or to trigger a prompt to ask the user for this (like in the example img).

Does anyone know of an asset, that can help me with this or if Unity has this feature already?

Help will be greatly appreciated!

Kind regards, Rasmus Lindholm

public void setBluetoothEnabled() { using (AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic ("currentActivity")) { try { using (var BluetoothManager = activity.Call ("getSystemService", "bluetooth")) { using (var BluetoothAdapter = BluetoothManager.Call ("getAdapter")) { BluetoothAdapter.Call("enable"); } } } catch (Exception e) { } } } @KuboRobot This will silently turn on bluetooth, without pop-ups because you grant permissions while installing an app, also, you have to add this to your AndroidManifest.xml: uses-permission android:name="android.permission.BLUETOOTH_ADMIN" uses-permission android:name="android.permission.BLUETOOTH" (probably not needed)

Thank you very much! Is there something similar to do this on iOS devices?

Its certainly possible but complicated, for IOS you will probably need to write plugin in C, this and this link might be helpful, there are some of them on Asset Store e.g. BTLE

@zyonneo Yes, and the answer is in this thread few posts above: This is a very good BLE plugin, that will give an error if Bluetooth is disabled, so you can ask user to turn it on and this is the way it should be done for the app stores to accept the app. We use the automatic way for the internal testing only: [Bluetooth LE for iOS, tvOS and Android][1] Also nRF Connect app is very helpful for discovering all IDs and characteristics of BLE devices.

@healthplexus The above answer is just a setBluetoothEnabled() function.I believe it is to turn on bluetooth device when we call that.How to get values from Beacon? Without Plugins is it possible?Else how to use plugins?How to connect it to a BLE devie and retrieve broadcasting messages?

@adammak23 Worked for us in Unity 2017.3.0f3 after this small change, thanks:` BluetoothAdapter.Call <bool>("enable");`
