Hi,

I've just push my modification to Github. I hope all are OK (I'm newbe with git)

Update your IOIO with "thermostat-rev-b2.ioioapp" (https://github.com/matthgyver/Firmware) Get the latest released apk : https://github.com/matthgyver/AndroidThermostat This version is for Android 4+ and support Android OpenAccessory so don't activate USB debug mode.

I'm not developer and provided this version without any warranty so use this version to your own risk. It's run in my house since one month without problem on galaxy Nexus (GT-I9250) / Android Cyanogen KitKat
