Abstract
A method and apparatus for synchronizing with a network without connecting to the network by shadowing a slave device while a master device connects the slave device to the network. The master device maintains a system clock time. The master and slave devices exchange communication traffic during time slots on channels in a channel hopping sequence derived from the system clock time. The method and apparatus obtain a slave clock time in an inquiry response packet from a slave device when the master and slave devices are not connected in the network and then use the slave clock time for shadowing the slave device for receiving a master page frequency hop synchronization (FHS) packet having the system clock time.
