I too have gone through that tutorial only to find Bluetooth connections not working. Working out that kink led me to coding up a IOIO Processing library of my own (check out https://github.com/PinkHatSpike/pioio).
Before you go any further though, you should confirm your Bluetooth dongle works with your setup first. The App-IOIO330 download should have a HelloIOIO.apk you can load onto your phone to do just that. BLE may be a little ahead of IOIO support, but I’m hoping it works out. Let me know what happens.
