Abstract

Disclosed is a communicating method capable of preventing data collision for a Bluetooth system which communicates with a plurality of other Bluetooth systems on a scatternet. The communicating method of a Bluetooth system comprises the steps of: receiving a communication request signal from a second external device; scanning the received communication request signal to convert the operation of the Bluetooth system from as the master to the first external device into as a slave to the second external device; and transmitting a mode-converting request signal into the second external device to convert the link state of the Bluetooth system with the second external device into a sniff mode in converting the operation of the Bluetooth system from as the slave to the second external device into as the master to the first external device. As converting the link state with the second external device into the sniff mode while operating as the master to the first external device, the Bluetooth system can execute efficient data communication with the plurality of other Bluetooth systems on the scatternet.
