Tool information

This tool reads out the supported elements and generates the appropriate PICS files for the device. The tool outputs the PICS for all endpoints and outputs these in a single folder.

Note: The tool does relay on what the the device is able to express and for now there are areas which the tool can not cover:

  • PICS in base.xml
  • Only mandatory events are marked as supported, since the global attribute with list of events is provisional

Setup

This tool uses the python environment used by the python_testing efforts, which can be built using the below command.

scripts/build_python.sh -m platform -i out/python_env

Once the python environment is build it can be activated using this command:

source out/python_env/bin/activate

The script uses the json based data model in order to convert cluster identifiers into PICS Codes. The file can be downloaded here: https://groups.csa-iot.org/wg/matter-csg/document/27290

NOTE: The tool has been verified using the “Specification_version 0.7-spring2024.json” version.

The script uses the PICS XML templates for generate the PICS output. These files can be downloaded here: https://groups.csa-iot.org/wg/matter-csg/document/26122

NOTE: The tool has been verified using V24 PICS (used for Matter 1.2 certification)

How to run

The tool does, as mentioned above, have external dependencies, these are provided to the tool using these arguments:

  • --cluster-data is the absolute path to the JSON file containing the cluster data
  • --pics-template is the absolute path to the folder containing the PICS templates
  • --pics-output is the absolute path to the output folder to be used

If the device has not been commissioned this can be done by passing in the commissioning information:

python3 'src/python_testing/PICSGenerator.py' --cluster-data <pathToClusterJson> --pics-template <pathToPicsTemplateFolder> --pics-output <outputPath> --commissioning-method ble-thread --discriminator <DESCRIMINATOR> --passcode <PASSCODE> --thread-dataset-hex <DATASET_AS_HEX>

In case the device uses a development PAA, the following parameter should be added.

--paa-trust-store-path credentials/development/paa-root-certs

In case the device uses a production PAA, the following parameter should be added.

--paa-trust-store-path credentials/production/paa-root-certs

If a device has already been commissioned, the tool can be executed like this:

python3 'src/python_testing/PICSGenerator.py' --cluster-data <pathToClusterJson> --pics-template <pathToPicsTemplateFolder> --pics-output <outputPath>
