AmbientPoly stops reporting data

[MClarke]

I set up AmbientPoly on a Raspberry Pi and everything seems to work initially. After some period of time (24 to 48 hours) it stops reporting data. The node server still shows "connected" during that time and restarting the node server will fix the problem. The error log is below:

Any thoughts?
