Data exchange method between Bluetooth devices in radio communications system using transport layer with upper transport layer in Bluetooth server and lower transport layers in base stations

摘要

The data exchange method uses a transport layer with an upper transport layer (HCl0) in a Bluetooth server (401) and lower transport layers (HCl11,HCl12,..HCl1n) in each of the base stations (201,202,..20n) of the communications system for management of the connection between a server application program and one of the base stations. A host-controller management unit (HCM) is arranged below the upper transport layer in the server, with host-controller subinstances (HCl01,HCl02,..HCl0n) respectively associated with the different base stations, allowing several application programms to be coupled with several base stations.
