UDMI / Docs / Tools / Reset Config

Send a configuration message to a specific device

The reset_config tool can be used to send a configuration message to a specific device.

The reset_config command can be invoked from the udmi folder in the following way:

bin/reset_config SITE_DIR PROJECT_ID DEVICE_ID [CONFIG_FILE]

For example, if the UDMI site model is in the path/to/site_model folder, if the GCP project ID is my_project and the device id is TEST-1, the command line will look like this:

bin/reset_config path/to/site_model my_project TEST-1

In this case, the reset_config tool will use the generated_config.json file that the registrar tool has created in the devices/TEST-1/out folder.

It is also possible to send a specific config payload.

In this case, it is necessary to store a file including the config payload in the devices/DEVICE_ID/config folder.

For example, if a file named config.json has been created for this purpose in the devices/TEST-1/config folder, it will be possible to invoke the reset_config tool with the following command:

bin/reset_config path/to/site_model my_project TEST-1 config.json

Finally, it is possible to get registrar to send a user defined config instead of a generated config file.

For this purpose, edit the metadata.json file to include the following cloud configuration object:

  "cloud": {
    "config": {
      "static_file": "config.json"
    }
  }

and store the config.json file in the devices/DEVICE_ID/config folder.
