## Abstract

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.

## Claims

### Claim 1

A method comprising:
receiving, via a low-power wireless connection, a new data query at a wearable device;
in response to the new data query, communicating to the client device, via the low-power wireless connection, a new data message identifying data stored on the wearable device;
receiving, via the low-power wireless connection, a connection communication from the client device, wherein the connection communication instructs the wearable device to activate high-speed wireless circuitry of the wearable device; and
communicating to the client device, via a high-speed wireless connection, the data stored on the wearable device.

### Claim 2 (depends on 1)

The method of claim 1, wherein communicating further comprises:
in response to receiving, via the low-power wireless connection, the connection communication, automatically communicating to the client device using a high-speed processor, via a high-speed wireless connection, the data stored on the wearable device, wherein the data is stored in a memory of the wearable device.

### Claim 3 (depends on 2)

The method of claim 2 further comprising:
communicating, prior to establishing the high-speed wireless connection, a connection unsuccessful communication to the client device; and
receiving a network adjustment command from the client device.

### Claim 4 (depends on 1)

The method of claim 1 further comprising:
receiving, via the low-power wireless connection, a sleep-state communication, the sleep-state communication instructing the wearable camera device to power down high-speed circuitry associated with the high-speed wireless connection; and
in response to receiving the sleep-state communication, powering down high-speed circuitry associated with the high-speed wireless connection.

### Claim 5 (depends on 1)

The method of claim 1 wherein the data stored on the wearable device is new camera data generated by an application on the wearable device.

### Claim 6 (depends on 1)

The method of claim 1 wherein the high-speed connection is an Institute of Electrical and Electronics Engineers (IEEE) 802.11 connection.

### Claim 7 (depends on 1)

The method of claim 1 wherein the low-power connection is a Bluetooth low energy (BLE) connection.

### Claim 8 (depends on 1)

The method of claim 1 further comprising:
communicating, prior to receiving, via a low-power wireless connection, a second new data message to the client device.

### Claim 9 (depends on 1)

The method of claim 1 further comprising:
performing a high-speed connection status check; and
encoding the new data message to indicate results of the high-speed connection status check.

### Claim 10 (depends on 1)

The method of claim 1 further comprising:
capturing second data from a camera of the wearable device; and
communicating to the client device, via a high-speed wireless connection, the second data.

### Claim 11 (depends on 1)

The method of claim 1 further comprising:
failing to establish the high-speed wireless connection within a threshold time period; and
receiving, from the client device using the low-power wireless connection, a sleep state communication; and
in response to the sleep state communication, powering down high-speed circuitry associated with the high-speed communication circuitry without communicating the data stored on the wearable device.

### Claim 12 (depends on 11)

The method of claim 11 further comprising:
in response to the sleep state communication, communicating the data stored on the wearable device to the client device.

### Claim 13 (depends on 1)

The method of claim 1 further comprising:
in response to a user command, capturing an image with a camera and storing the image as the data stored on the wearable device.

### Claim 14 (depends on 1)

The method of claim 1 further comprising:
performing a high-speed connection status check; and
communicating to the client device, via the low-power wireless connection, results of the high-speed status check.
