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 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

First change the directory to the tool location.

cd src/tools/PICS-generator/

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

  • --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 PICSGenerator.py --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 PICSGenerator.py --pics-template <pathToPicsTemplateFolder> --pics-output <outputPath>
