Methods and systems for auto coexistence priority selection for a SCO link are disclosed. Aspects of one method may include a first Bluetooth device communicating with a collocated WLAN device via a coexistence method. The first Bluetooth device, prior to executing a non-SCO task, which may comprise tasks that do not involve SCO packet transfer, may communicate low priority via the coexistence method if a Bluetooth SCO link is present between the first Bluetooth device and a second Bluetooth device, and if a current task being handled by the first Bluetooth device is a high priority task. If a SCO link is not present between the first and second Bluetooth devices, and if the current non-SCO task is a high priority task, the first Bluetooth device may communicate high priority via the coexistence method prior to executing the non-SCO task.

Methods and systems for enhanced 2-wire and 3-wire WLAN Bluetooth coexistence solution may include determining whether adaptive frequency hopping is active in a Bluetooth communication device. If the adaptive frequency hopping is active, handshaking with a collocated non-Bluetooth communication device may be disabled. The collocated non-Bluetooth communication device may be a wireless local area network communication device. If the adaptive frequency hopping is inactive, handshaking with the collocated non-Bluetooth communication device may be enabled. If the adaptive frequency hopping is inactive, the Bluetooth communication device may initiate handshaking prior to transmitting data. If the adaptive frequency hopping is inactive, the Bluetooth communication device may also respond to the handshaking initiated by the collocated non-Bluetooth communication device. The handshaking may be executed via a 2-wire Bluetooth/WLAN coexistence interface or a 3-wire Bluetooth/WLAN coexistence interface.

Methods and systems for dynamically changing poll timing based on Bluetooth activity are disclosed. Aspects of one method may include determining synchronous Bluetooth activity between a Bluetooth master device and at least one Bluetooth slave device. The synchronous Bluetooth activity may comprise, for example, transmission of packets by the Bluetooth master device via a SCO link and/or a eSCO link. The Bluetooth master device may dynamically adjust a polling period based on the synchronous Bluetooth activity. For example, the polling period may be less when there is synchronous activity than when there is no synchronous activity. The polling periods for when there is synchronous activity and when there is no synchronous activity may be default values. The default polling periods may be changed to different values, for example, by the user.
