Systems and methods for wearable initiated handshaking
Systems and methods for device handshaking are described. Embodiments for client device and associated wearable device initiated handshaking are described. In certain embodiments, a device such as wearable camera eyeglasses having both high-speed wireless circuitry and low-power wireless circuitry communicates with a client device. The low-power wireless circuitry is used for signaling and to manage power on handshaking for the high-speed circuitry in order to reduce power consumption. An analysis of a high-speed connection status may be performed by a client device, and used to conserve power at the glasses with signaling from the client device to indicate when the high-speed circuitry of the glasses should be powered on.
