Primary updates include: Link Devices, ability to unclaim a device, and Device Info.
Link Devices - If you have more than one Cube ( or Particle device) running Spark Pixels, you can link them together allowing you to control them at the same time. The commands are sent sequentially (not simultaneously) so expect a slight delay. Each device can be configured individually. i.e. Cube A can be configured to link Cubes A, B and C. And Cube B can be configured to only link B and C. So when Cube A is selected in the app, A, B and C can be controlled at the same time. But when B is selected, only B and C will be controlled. And when C is selected, it will only control itself. Make sense?? Good. Play around with it and you'll see what I mean.
Device Info - Get Device ID, IP Address, Local IP Address, WiFi Strength, Firmware Rev, Particle Build Version, Current Time on Device, etc. Customize what you want in the sketch. The app gives you the ability to copy each value to the clipboard of your Android device. This could be useful to get your local IP address when using @wmoecke's LISTNER mode. I don't have a Cube Viz coded for you to try out right away, so you'll have to follow my instructions to add it to your sketch yourself.
