Use Galaxy Nexus as a Transformer Prime Game Controller

If you have an Android smartphone and the Transformer Prime, here’s how to pair them to use the Galaxy Nexus as a game controller.

I set this up using a CDMA Galaxy Nexus and an Asus Transformer Prime TF-201. I’m sure it will work on other Android devices with other games too. If you have done this on other Android hardware, leave a comment and let us know.

Do you have a tablet that has Bluetooth and is fast enough to play Sonic CD? Wish you could use an actual controller to completely PWN Dr. Robotnik? Well, if you can’t figure out how to use your Nintendo Wii controller, here is the next best thing. Use your Galaxy Nexus or any other Android 2.1 device or higher as the controller.

This was tested playing Sonic CD, Nesoid, Riptide GP and Mame4Droid. There is a free and a paid version, both of which work great. I especially like apps like this that allow us to use our devices in new and exciting ways.

Let’s start things off by assuming you’ve downloaded either the BT Controller free or paid version onto both your phone and your tablet. We’ll also assume you’ve turned Bluetooth on. Start up BT Controller on each device.

Tap visible on the tablet to make the device discoverable. You will get a warning about other Bluetooth devices finding your device within the 300 seconds time frame. Tap Yes.

Once it finds the device, tap connect on the phone.

Tap scan for devices and you will see it show up. Tap pair once you’ve checked the code it shows you. It’s the same on each device. It worked perfectly the first time pairing the Galaxy Nexus to the Transformer Prime, but it took a few tries pairing the Droid X to the Prime.

It will ask you which device you want as the controller, and which device is the host. On the phone tap controller, or tap host on the tablet.

You’ll see the controller interface on your phone.

There are two boxes in the upper right of your tablet. KB Enabled and KB Active. These are letting you know that you are paired, but not enabled or active. Tap the KB Enabled box.

That brings you to the Language and Input setting. Tap BT Controller. Notice KB Enabled is now checked in the upper right.

Now tap KB Active. That brings you to the Select Input Method dialog. Remember, this is changing your current input method. So if you try to type something, it might look weird until you switch back to the keyboard of your choice. But for the duration of our time playing Sonic CD, we’re going to want BT Controller as our active input method.

Check to see if everything is working. The Controller box is on the upper right of the tablet. Tap the direction pad on the phone right, to move icons and eventually to the next home screen to the right. Tap the buttons on your phone and you will see them show up in the upper right.

Now that we have the controller paired, enabled and activated, let’s fire up Sonic CD. SEGA!

If everything is working properly, you should be able to tap Start on your phone / controller and get the game started. Pretty cool right?

Sure that was easy, but do you know how to make BT Controller work with your favorite rom emulator? Check out my groovy how to on it!

    This is awesome. I will try with my Galaxy S and Acer 500 tab and get back to you.
