What is the best way to go about learning to program in bluetooth - by that I mean not only the cheapest product, but are there any licence free ways to devlop Bluetooth applications. say for example - is it possible to develop applications for Bluetooth mobile phone that are royalty free? I've looked onthe Nokia webiste and it talks about an SDK for C++ - I thought there might be one for Java. What class do most mobile phones have? And are most now switching to version 1.2 ?
