As today (July 2002) there is no doubt that a wireless revolution has arrived. As internet communication is growing stronger, more suitable and advanced techniques are used to integrate offices and home based networks to this new standard.
A still somewhat sleeping and awaiting market actor to this new technology is the industrial one. The Blueboat application is meant to replace cables in a military marine system, showing that the wireless solution is as least as good and more flexible as the traditional based on cables.
Our task was to send system information such as course, speed and depth from an internal rack to a client computer via Bluetooth. The system information is to be received, interpreted and logged on some kind of software (Bluboat) at the client computer.
To do this we are using a microcontroller that is listening on a serial port to receive the information that is to be transmitted. In the microcontroller the data packets are reformatted to Bluetooth packets which are sent to a Bluetooth device connected to the microcontroller
On the client side the Bluetooth packets are received and formatted so that it is possible to read real-time data on e.g. a laptop anywhere in the near facility.
