My Opinion:
Sensor Tag from Broadcom is very slick sensor packed Sensor Tag evaluation kit, unfortunately I cannot figure out where to get software and how to program this Sensor Kit, seems like it design only for demonstration purposed without any ability to tinker with it, this is a bit disappointing. I will continue my research but so far I don’t see anything available online.
