Abstract:
1. A method for communicating with seven or more terminals in a Bluetooth system having a master and a plurality of slaves, the method comprising the steps of: checking that an active member address remains available to be allocated to a new slave such that the master establishes a communication connection with the slave; in case an active member address remains available, allocating the remaining active member address to the slave, and in case no active member address remains available, calculating a service delay time and comparing the calculated delay time with a predetermined reference value; in case the service delay time is larger than the predetermined reference value, refusing a call acceptance, and in case the service delay time is smaller than the predetermined reference value, converting a slave that has requested the call to sniff mode and determining a service sequence with respect to a predetermined reference according to the number of the slave calculated at a pre-scheduling duration; allocating and giving a sniff interval time and an active member address to each of the slaves according to the service sequence, the sniff interval time being determined by an equation of SIT=N*F+N waking of a slave from sniff mode at the sniff interval time and using the active member address to complete the communication with the active master and to return a use right of the active member address.
