In my opinion the key growth factor of Bluetooth is 4.0LE. Legacy Bluetooth (2.1EDR) is hugely successful in Cell-phone accessory market (Headset, keyboard and mice) but I don't think there's large growth margin anymore.
BT4.0LE was introduced three years ago with high hope. However market adaptation was rather slow, due to lack of direct compatibility with legacy Bluetooth and slow software development. Currently Apple is leading the BTLE market, Microsoft (Windows8) and Google (Android 4.2) is catching up after about two years of delay.
It seems line all three major platform (iOS, Android and Windows) became BTLE ready at last, so it could be true that year 2013 will have BTLE breakout - or not, who knows.
Absolutely agree. You're going to see Bluetooth 4.0 in EVERYTHING in the next few years. One of the reasons for Apple's domination thus far is that they included access to the hardware in their iOS API. Android devices could not use Bluetooth 4.0 even though the hardware was there!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
