Bug InputSystem Rumble should not be used with Bluetooth Controllers

Use the following code to set the Rumble on a Xbox Controller:

Code (CSharp):

1. Stopwatch stopwatch;
2.  
3. private void Start()
4. {
5.     stopwatch = new Stopwatch();
6. }
7.  
8. private void Update()
9. {
10.     stopwatch.Start();
11.     gamepad.SetMotorSpeeds(1f, 1f);
12.     stopwatch.Stop();
13.     UnityEngine.Debug.Log($"Rumble took {stopwatch.ElapsedTicks / 10000f} milliseconds");
14.     stopwatch.Reset();
15. }

When the controller is connected with USB this will take a miniscule amount of time of around 0.03ms.
When the controller is connected with Bluetooth this will take a long amount of time of around 0.70ms.

The rumble command, once sent, will wait for a response from the controller that the command was received. The round trip is unacceptable. This shouldn't be a blocking call.

 

Sorry, I forgot to include that:
(Case 1364574) InputSystem uses too much CPU when setting rumble on a Bluetooth controller
