Bluetooth radio communication systems (1,2) are made more dynamic by providing master units (3) with processor systems (32) having user interface applications (81), profile applications (83,84) and manager applications (82) for providing interfaces to the user interface applications (81), for managing the profile applications (83,84) and for searching for and retrieving information from one or more slave units (4-7). The manager applications (82) are in the form of intermediate layers between user interface layers and profile layers. The retrieved information comprises identification information and profile information. The profile applications (83,84) comprise headset (84) and/or intercom (83) profile applications. The manager applications (82) comprise state machines with idle states (100), search states (110), connection request states (120) and connection respond states (130). The master units (3) comprise man-machine-interfaces (34) with two selection buttons and one or more arrow buttons. As a result, slave units (4-7) as well as their profile applications do not need to be known to the master units (3) beforehand. |
