@Gordon
Could you close/reopen the IDE? It seems to be in kind of an odd state.
Does anything happen on Puck.js during that time?
You could also try booting Puck.js with the button held down until all 3 LEDs come on. On 1v93 that should clear out any pairing information (or garbage that might have got left in that area from older versions of the firmware).
