It uses a Serial Data Stream system and has fairly short range of up to a few meters. The secure element is entirely up to the implementation and may not be present at all. It is fairly limited in the types of communications it supports, but the ability to support a virtual serial port is its strength. At its cost, and the high barrier of entry for development, it is currently mroe economical for a robot developer to look at more simple wireless serial port pairs, or a basic RC protocol.
For robots, off the shelf bluetooth chips, like the HC-06, are available and can be interfaced with microcontrollers. Bear in mind the relatively short range of such systems.
|Bluetooth: Operation and Use (E-BOOK: ADOBE READER)||Robert Morrow||This book is a reference and starting point for those looking into using BlueTooth in systems, although not directly set for robots - it is a worthwhile guide. Being an e-book, you can read it on your PC, or PDA and not clutter your desk(the whole point of BlueTooth!)|
|Bluetooth 1.1: Connect Without Cables||Joe Mendolia (Foreword), Jennifer Bray, Charles F. Sturman||A very complete guide to the BlueTooth 1.1 standard. This is worthwhile using if you want to ensure compatibility, and is orientated to networking. As it covers power saving - it is very suitable for robot builders wanting to use BlueTooth.|
Time to build your own robot! Using a Raspberry Pi with parts and some time, you can use my book to learn how to make and program a robot with automatic behaviours.
