Two approaches for resolving number limitations of the equipments connected in Bluetooth communication

Bluetooth has the limitation that only eight equipments were allowed to be connected. Generally, the number of the devices, which have the connecting request, is more than the number that was allowed in automatic processes. In this paper, we proposed two approaches to achieve the solution. The first, PM_ADDR and Master were used in keeping time connecting through changing the mode of the Slave equipment from Active into Park. The second, we create new Piconets with the topologies to all Bluetooth devices based on constructing Scatter net. In net searching and communicating processes, the distance relations associated to the other Bluetooth equipments were evaluated by the values of RSSI obtained from the communicating interface, while the equipments were connected.
