Device Configuration

The device.json5 configuration file contains device identification and descriptive properties to uniquely identify a device. It is used during device registration and cloud provisioning.

The device.json5 contains properties for:

  • The device unique ID
  • A product token indicating which product on which the device is based
  • When the device was made
  • Identifying description and model strings
  • Whether the device is a test device

You can also add any other properties to the device.json5 that may provide useful device context. These properties will be saved in the cloud device database and will be available to device managers.
