Rediscovering Bluetooth
Presenting Bluetooth in 2006 is hard. By all accounts, it should have emerged much sooner to be omnipresent by now. Yet it did not succeed as planned and therefore carries a bad reputation. Bluetooth is popular, but not as popular as WiFi. However, you can do a lot more with Bluetooth, especially with casual hacking.
Do you know Bluetooth? You may already be familiar with it, and even use it, perhaps with your cellphone and wireless headset. If so, you may wonder what more Bluetooth can do for you, especially if you have read only technical literature about its theoretical aspects–full of overused buzzwords such as “piconets” or “scatternets,” but devoid of any real-world application or implementation.
Do not worry. This article shows you how to play with Bluetooth, not buzzwords. If you are not familiar with Bluetooth, I hope to introduce you to such a nifty technology, and guide you through my wonderful world of Bluetooth, with wireless gizmos everywhere!
This article demonstrates how to make your Bluetooth module work, scan for other Bluetooth devices and see which services they can offer, and connect to them. I provide a service named PAN, which can perform wireless IP networking with Bluetooth.
