US Patent 11928478 Tracking device state transitions

An example computing device includes a tracking device, an interface, a processor, and a controller. The interface including a power pin, a data pin, and a clock pin, where the interface is to couple the tracking device to the computing device via the power pin and the data pin, and the clock pin is disconnected from the tracking device. The controller is communicatively coupled to the processor and the interface, the controller is to control an operation of the tracking device via the data pin.
