Skywriter touch inputs not working?


I have recently set up a Skywriter with an Arduino Nano. The 3D position sensing works great, however the touch and gesture and outputs appear to be not working.

Every line is in this format:

42021:57026:00000 gest:03 touch:09

The numbers for gesture and touch change (slightly unreliably) on touch but the numbers do not seem to correlate to any particular area of the sensor for touch or gesture in that case.

Any input appreciated!
