There are two separate issues here I believe:
- (this is the more fundamental one): Bluetooth is not keeping up with
having 12 analog inputs open at the same time. Your options are either:
- Try a different dongle.
- Use USB.
- Modify the firmware to reduce the analog input reporting rating
(currently hard-coded at 1KHz).
- (this is a side-effect): As result of BT not keeping up, the Android
receives corrupt data and not handling it gracefully. I believe this issue
has been fixed in the recent IOIOLib versions.
