The root cause is corruption in the data coming in. IIRC, you're using Bluetooth, with a number of analog inputs, and it might be that the connection is not keeping up until eventually dropping data.
I recently changed the behavior of this failure mode to not crash the app, and IOIOLib seems to do the right thing from your logs, only that the connection doesn't get re-established for some reason. Do you see an attempt to reconnect in the rest of the logs? Things that might fix that: - Try a different dongle. I've seen different bandwidths by different dongles. - Build a custom firmware image that reduces the analog sampling rate (code change is very easy, building the firmware is a little trickier).
