The wireless nature and the mobility of Bluetooth enabled devices combined with the heterogeneity of the wide range of hardware and software capabilities present in those devices makes Bluetooth connection and resource management very complicated and error prone. To manage such diversity of software and hardware, middleware technologies masking the underlying platforms have been designed. One such middleware solution for Bluetooth based on common object request broker architecture (CORBA) is introduced and the mapping of GIOP messages to Bluetooth logical link control and adaptation protocol (L2CAP) links is explained in detail. The paper also describes how CORBA policy objects influence object reference creation and service contexts in the request/reply sequences and how client-server transport level quality of services (QoS) negotiations are achieved through QoS information embedded in object references and service contexts
