Page and Connect States • After receiving a response from devices, the master can connect to each device individually • An AMA is assigned • Slaves synchronize to the hopping sequence established by the master standby inquiry page • In active state, master and slaves listen, transmit and receive • A disconnect procedure allows devices to return to standby mode Transmit AMA Park PMA Hold AMA Connected AMA Sniff AMA
Low Power States • Sniff state • Slaves listen to the piconet at a reduced rate • Master designates certain slots to transmit to slaves in sniff state standby • Hold state • Only internal timer is running • Slave stops ACL transmission, but can exchange SCO packets Transmit AMA inquiry page Connected AMA • Park state • Slave releases its AMA • Still FH synchronized and wakes up periodically to listen to beacon Park PMA Hold AMA Sniff AMA
