3 Improve bluetooth performance and input lag

I will explain here, how you can improve the performance of the bluetooth globally and certainly the "Input lag" with bluetooth controllers. Perhaps, with this trick, you'll have a better experience in game with Xcloud Beta.

You'll need to eanble the developers mode in the shield

Unlocking the Developer Mode

Go to Settings -> Infos

And tap many times to the "build version" for display the "Developer mode".
Go to the developer mode section.

Change AVRCP version

After that search this feature : "AVRCP” and “Bluetooth AVRCP version”.

Choose the last version and validate.
You can now test in your games the results, it's working well for me.
