Abstract: Systems and methods for Bluetooth voice link shadowing are disclosed. A primary device may receive an eSCO packet from host device over master slot(s) of an enhanced synchronization connection oriented (eSCO) window within an interval of a host piconet shared between the host and primary devices. A secondary device may sniff for the eSCO packet also over master slot(s) of the eSCO window. When the primary device successfully receives the eSCO packet from the host, it may unconditionally relay the packet to the secondary device. Alternatively, it may conditionally relay the packet when the secondary device does not successfully sniff the packet. When the secondary device successfully sniffs the eSCO packet from the host, it may unconditionally relay the packet to the primary device. Alternatively, it may conditionally relay the packet when the primary device does not successfully receive the packet.

Abstract: System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperature-calibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperature-calibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device.
