A METHOD FOR SYNCHRONIZING IDLE MODE WAKEUP TIMES FOR A BLUETOOTH MODULE AND A WIRELESS MODULE IN A DUAL MODE BLUETOOTH/WIRELESS UNIT

摘要

In a dual mode Bluetooth/wireless mobile unit, the next sleep mode Bluetooth wakeup time is rescheduled to synchronize with any upcoming idle mode wireless wakeup time that will otherwise precede the Bluetooth wakeup time. The Bluetooth clock is advanced, or other reconfiguration made to the Bluetooth module, as appropriate to prevent the scanning frequency from changing during a sleep mode Bluetooth wakeup/scanning interval commencing at the resynchronized Bluetooth wakeup time.
