Abstract
A slave Bluetooth device establishes first and second connections with first and second master Bluetooth devices, respectively, that each operate in a master mode. The slave Bluetooth device operates in a slave mode when communicating through any of the first and second connections. The slave Bluetooth device communicates connection parameter update request packets containing timeout values to the first and second master Bluetooth devices. The slave Bluetooth device alternates during non-overlapping time slots between at least: 1) monitoring the first connection for traffic transmitted by the first master Bluetooth device while not monitoring the second connection; and 2) monitoring the second connection for traffic transmitted by the second master Bluetooth device while not monitoring the first connection; and controls a rate at which the alternating is performed based on the first timeout value and the second timeout value.
