Abstract: For its low-cost and low-power, Bluetooth, the wireless access becomes first choice of the intelligent housing system. But because of the interference among the houses and among the different networks, the speed of device identification and construct network of the Bluetooth controller is been effect. This paper uses the CoD field of FHS group package to carry the message of housing marker and network marker, effectively reduces the interference between Bluetooh devices, accelerates the process of device identification and the speed of construct network. Finally, the paper makes a key analysis at the case of Bluetooth device enter and exit the intelligent housing system, the feasibility of whole system is ensured.

Key words: Bluetooth, device identification, construct network
