Patent attributes
The present disclosure describes a system and method for resetting firmware in an electronic accessory, such as a wearable electronic device, without a physical reset button on the accessory. A secondary device, such as a case for the accessory, can serve as a power source that initiates the reset. The reset may be manually initiated, for example by a user pressing a button, or automatically initiated, such as by the secondary device detecting that the accessory is unresponsive. The secondary device sends a reset command to the electronic accessory through a power line connection. The power line connection may be made, for example, upon contact of the accessory with the secondary device. In some examples, the reset command may be an elevated power level. Upon receiving the reset command through the power line, the accessory completes the reset.
