Master apparatus for bluetooth communications and method of forming beacon channel

The master device and the beacon channel forming method for performing a communication with the slave device by the Bluetooth system is disclosed. The master device according to the present invention, a slave that receives the signal transmitted from the slave device, maintain the transmission / reception section and the number and the synchronization connection of the slave devices park from the signal received from the transmitting / receiving unit to transmit the transmission target signal connection for calculating the state information including the type of the device computing unit and a beacon slot number to be applied for the beacon channel for maintaining the slave device and the communication channel park from the state information provided from the connected state output unit and access window and a control unit that processes the park parameter calculating section for calculating the park parameters including the number per slot, so it can communicate over the slave unit and the transmission / reception unit according to the calculated park parameters. According to such a master unit and a beacon channel-forming method, the synchronization according to the connection type of the slave unit is in the state and the number of park slave device, the number of slots of the beacon channel no unnecessary surplus is not generated properly varying sikimeuroseo, master and slave devices with the communication efficiency it can be maintained for the communication channel to be increased.
