So who was it that invented Bluetooth? The short answer is Swedish telecommunications company Ericsson. The team effort began in 1989 when the company's Chief Technology Officer of Ericsson Mobile Nils Rydbeck and Johan Ullman, a physician, commissioned engineers Jaap Haartsen and Sven Mattisson to come up with an optimal "short-link" radio technology standard for transmitting signals between personal computers to wireless headsets that they were planning to bring to the market.
So why choose Laird. Well most of all because it comes with its own compiler, using some sort of basic, called Smart Basic. Although I do not understand that very much of basic, I am nevertheless able to put some code together. Thanks to their many example's.
The code compilation and upload, works just fine.The BT900 has pin's, many of wich I do not use, eccept their serial communikation.
Unfortunately, the module is too small for me to handle.
