When opening an analog input, the IOIO starts streaming samples to the
Android at 1kHz. If the Bluetooth stack is flaky, this might load it enough
to break it. I've definitely seen some Android devices with poor Bluetooth
implementations. You might have encountered one. I would also try a
different dongle in case this is a compatibility issue.
