The present invention provides a communication system comprising a Master
unit (1) and at least one Client unit (3), means to automatically
establish a wireless bi-directional connection between said Client unit
and said Master unit when they are close together; and means to
automatically configure a communication interface (5) between said Master
unit and said Client unit after connection is established. The invention
thus enables systems with different protocols to find and communicate via
said configured communication interface (5).
