Abstract: Based on the Bluetooth specification and LAN access profile, this paper presents the design and implementation of two versions of Bluetooth LAN access point (LAP). Firstly, the paper illustrates the LAN access profile in Bluetooth specifications in brief. Then, the design and development of LAP based on PC are discussed. Afterward, the implementation of embedded LAP is presented together with its key techniques,for example double module, VOS, multi-course, virtual serial port technique etc. The experimentation results show that LAPs developed satisfy the Bluetooth technology standard and the connection is very good with other Bluetooth equipment manufactured by other companies. The LAP both based on PC and embeded has had our intellectual asset and patent(IP) and is applied many fields so the industrialization foreground is very bright.
