Connect to the glasses and retrieve device status

Overview​

The device_connect example shows how to connect to your Project Aria device using the Client SDK and retrieve:

  • Device status, such as such as battery level, Wi-Fi SSID or Wi-Fi IP address
  • Device information, such as the device serial number or device model

Running the sample​

In your terminal, from the samples directory, run:

python -m device_connect

You should then see:

[AriaSdk:DeviceControllerImpl][INFO]: Connecting to device <serial_number> using ADB
[AriaSdk:DeviceClientImpl][INFO]: Connection established with device <serial_number>
Aria Device Status: battery level 100, wifi ssid <xxxxxxxx> , wifi ip <192.168.xx.xx>, mode DeviceMode.Partner
Aria Device Info: model Aria, serial <serial_number>
Aria Device Connected, disconnecting

Code walkthrough​

1. Create and configure a Device Client​

DeviceClient allow you to connect to Project Aria glasses over Wi-Fi or USB.

device_client = aria.DeviceClient()

By default, DeviceClient connects to Aria glasses over USB. To connect to glasses over Wi-Fi, configure the DeviceClient by creating a DeviceClientConfig, setting ip_v4_address and setting the config.

client_config = aria.DeviceClientConfig()
if args.ip_address:
    client_config.ip_v4_address = args.ip_address
device_client.set_client_config(client_config)
info

Get your Aria glasses' IP address from the Mobile Companion App by tapping Wi-Fi on the Dashboard.

2. Connect to a Device​

Connect to the Aria glasses and retrieve a Device instance. An Exception will be thrown if the connection is not successful.

device = device_client.connect()

3. Fetch device status and information​

We can then obtain the device status and information:

status = device.status
print(
    "Aria Device Status: battery level {0}, wifi ssid {1}, wifi ip {2}, mode {3}".format(
        status.battery_level,
        status.wifi_ssid,
        status.wifi_ip_address,
        status.device_mode,
    )
)

Check out the full status list.

info = device.info
print(
    "Aria Device Info: model {}, serial {}, manufacturer {}".format(
        info.model, info.serial, info.manufacturer
    )
)

Check out the full information list.

4. Disconnect​

Once all operations have been completed, you can disconnect from your glasses to release any held resources.

device_client.disconnect(device)
