Systems and methods for controlling sensor devices in mobile devices

Abstract

Systems and methods for controlling one or more sensor devices are disclosed. In one embodiment, a system of a mobile device for controlling one or more sensor devices comprises an application processor (AP), a low power personal area network (PAN) module configured to wirelessly communicate with an external device for establishing a connection with the external device, at least one sensor device, and a controller coupled to the AP, the low power PAN module and the at least one sensor device. The controller is configured to monitor a connection request signal communicated from the external device via the low power PAN module while the AP is in a sleep mode, and generate sensor data by processing each signal from the at least one sensor device during the sleep mode, where the controller is supplied with quiescent current from a battery of the mobile device during the sleep mode.
