This free version of Bluetooth Control Keypad allows electronics experimenters, makers and other creative individuals control their Bluetooth-enabled creations using an Android phone or tablet. I built this app so I could easily cut the cord and control my creations without wires. The app comes with three ready-to-use sample keypad layouts and gives you the ability to develop and save your own intuitive key layouts for transmitting ASCII characters (even non-printing characters) to your devices.

This app is a MUST for all developers looking for an easy intuitive way to control their custom Bluetooth-enabled devices. I've tried Bluetooth terminal apps ... but if you want an intuitive layout, you have to tailor your device commands to a standard keyboard. In addition, with a terminal app, all of the keys are on the screen all of the time ... and there is generally no way to send non-printing control characters.

This free version features no advertisements and a simple, no frills, interface. You can save up to 5 custom layouts consisting of up to 6 keys. If this idea works well for you, you can download the extended version (XT) and support further development and future enhancements. The app has been tested on 7" tablets, small phones and large phones ... it all just seems to work. For more information, visit http://bluetoothkeypad.eclecticstudio.com.

This app was developed using MIT App Inventor 2. Thanks to MIT for picking up the project started by Google and released into the public domain.
