If somebody wants a working demo of a Bluetooth Low Energy Watch, then just drop an email to harald.naumann (at) gsm-modem.de. The evaluation kit for a Bluetooth Low Energy IC I have in my cupboard. One of my customers is in the watch industry and developed a watch with long-wave radio inside. Bluetooth Low Energy also called Bluetooth Smart is on 2400 MHz. An 2400 MHz antenna at a watch is an easy task.
At Kickstarter they try to collect USD 150.000 to start the project. If somebody like I can ask what my customer has to charge. With a little luck we can use the enclosure and the wristband of the old long-wave project.
