Bluetooth Controller is a simple app that allows you to send Bluetooth messages to a paired device. If you have built an Arduino or Raspberry PI robot for example you can get your device to respond to commands sent by your phone.

Upon pressing a button the app will attempt to connect to the selected device and send a message to it.

The connection will be maintained until a disconnection occurs or another device is connected to (in this app).

I usually use the HC-06 Bluetooth module in my projects to receive message from my phone. These are cheap and can easily be purchased online.

The chart within the app will show you which string is send for each of the different buttons.

By watching for these strings in your connected device you can associate a function with them.

It is my intention to update the app to make these commands editable as well as adding additional controller interfaces.

Swipe to change to different control modes.
