Matter Certification
====================

The Matter Certification denotes compliance to a Connectivity Standards Alliance (CSA) specification for the product and allows the use of Certified Product logos and listing of the product on the Alliance website for verification.

You need to `become a member <https://csa-iot.org/become-member/>`__ of CSA and request a Vendor ID code from CSA Certification before you apply for a Matter Certification. Then you need to choose an `authorized test provider <https://csa-iot.org/certification/testing-providers/>`__ (must be validated for Matter testing) and submit your product for testing. Below are the steps for the Matter Certification.

Firmware Development
--------------------

Choose an esp-matter branch
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Use the branch corresponding to the Matter version you plan to certify for firmware development.

.. list-table:: esp-matter Branches Mapping

   * - Matter Version
     - esp-matter Branch

   * - Matter 1.5
     - `release/v1.5 <https://github.com/espressif/esp-matter/tree/release/v1.5>`__

Product Attestation Authority (PAA) Generation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Matter certification testing, vendors should generate the test Product Attestation Authority (PAA) certificate, Product Attestation Intermediate (PAI), and Device Attestation Certificate (DAC), rather than using the default test PAA certificate from the connectedhomeip SDK repository. Therefore, you need to generate a PAA certificate and use it to sign the PAI certificate, which is then used to sign the DAC. The PAI certificate, DAC certificate, and DAC private key should be stored in the product under test.
The `chip-cert <https://github.com/project-chip/connectedhomeip/blob/master/src/tools/chip-cert/README.md>`__ tool which is built in `esp-matter setup <https://github.com/espressif/esp-matter/blob/main/docs/en/developing.rst#2-esp-matter-setup>`__ process can be used to generate the PAA certificate and Certification Declaration (CD).

::

    cd $ESP_MATTER_PATH/connectedhomeip/connectedhomeip/out/host/
    ./chip-cert gen-att-cert --type a --subject-cn "Example PAA CN" --subject-vid 0x131B \
                                --valid-from "2021-06-28 14:23:43" --lifetime 4294967295 \
                                --out-key /path/to/PAA_key \
                                --out /path/to/PAA_certificate

Certification Declaration (CD) Generation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Certification Declaration (CD) is a cryptographic document that proves a Matter device complies with protocol standards. For Matter certification testing, users should issue a test CD based on the test CD signing keys in the connectedhomeip SDK repository. This test CD should match the Vendor ID and Product ID in the test DAC, as well as the information in the BasicInformation cluster. During certification testing, the CD's --certification-type should be set to 1 (provisional), while the official CD issued by CSA after passing certification will have --certification-type set to 2 (official).

::

    cd $ESP_MATTER_PATH/connectedhomeip/connectedhomeip/out/host/
    ./chip-cert gen-cd --format-version 1 --vendor-id 0x131B --product-id 0x1234 \
                                --device-type-id 0x010c --certificate-id CSA00000SWC00000-01 \
                                --security-level 0 --security-info 0 --version-number 1 \
                                --certification-type 1 \
                                --key $ESP_MATTER_PATH/connectedhomeip/connectedhomeip/credentials/test/certification-declaration/Chip-Test-CD-Signing-Key.pem \
                                --cert $ESP_MATTER_PATH/connectedhomeip/connectedhomeip/credentials/test/certification-declaration/Chip-Test-CD-Signing-Cert.pem \
                                --out path/to/test_CD_file

Factory Bin File Generation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Based on the test PAA and CD generated above, users can use `esp-matter-mfg-tool <https://github.com/espressif/esp-matter-tools?tab=readme-ov-file>`__ to generate the corresponding factory partition bin file. This file contains commissioning information (discriminator, salt, iteration count, and SPAKE2+ verifier), device attestation information (Certification Declaration (CD), Product Attestation Intermediate (PAI) certificate, Device Attestation Certificate (DAC), and DAC private key), device instance information (vendor ID, vendor name, product ID, product name, etc.), and device information (fixed label, supported locales, etc.). This information is used to identify the product and ensure secure commissioning.

In the reference command below, the -n option specifies the number of factory bin files to generate. esp-matter-mfg-tool will first generate the PAI certificate and key, then use them to generate the specified number of different DAC certificates and corresponding keys. The tool will use the generated certificates and keys to create multiple factory partition binary files with different DACs, discriminators, and setup pincodes.

::

    python3 -m pip install esp-matter-mfg-tool
    esp-matter-mfg-tool -n <count> -cn Espressif --paa -c /path/to/PAA_certificate -k /path/to/PAA_key \
                        -cd /path/to/CD_file -v 0x131B --vendor-name Espressif -p 0x1234 \
                        --product-name Test-light --hw-ver 1 --hw-ver-str v1.0

Firmware Configuration
~~~~~~~~~~~~~~~~~~~~~~~

When generating test product firmware, the following configurations can be set in menuconfig to enable accessing the information from the factory bin file generated above:

::

    CONFIG_ENABLE_ESP32_FACTORY_DATA_PROVIDER=y
    CONFIG_ENABLE_ESP32_DEVICE_INSTANCE_INFO_PROVIDER=y
    CONFIG_ENABLE_ESP32_DEVICE_INFO_PROVIDER=y
    CONFIG_FACTORY_PARTITION_DAC_PROVIDER=y
    CONFIG_FACTORY_COMMISSIONABLE_DATA_PROVIDER=y
    CONFIG_FACTORY_DEVICE_INSTANCE_INFO_PROVIDER=y

OTA File Generation
~~~~~~~~~~~~~~~~~~~

If the test device supports standard Matter OTA, you need to prepare OTA files for certification testing. (Note: You can add OTA `rollback <https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/system/ota.html#app-rollback>`__ functionality to facilitate certification testing)

In esp-matter projects, change the firmware version number by modifying the PROJECT_VER and PROJECT_VER_NUMBER values in your application's CMakeLists.txt file. When generating OTA files, you need to use firmware with a higher version number than the one currently running on the device.

Use `ota_image_tool.py <https://github.com/project-chip/connectedhomeip/blob/master/src/app/ota_image_tool.py>`__ to generate Matter OTA files, where the ``-vn`` parameter is the software version number, and the ``-vs`` parameter is the software version string:

::

    cd $ESP_MATTER_PATH/connectedhomeip/connectedhomeip/src/app
    ./ota_image_tool.py create -v <vendor-id> -p <product-id> -vn 2 -vs 1.1 -da sha256 \
                            /path/to/original_app_bin /path/to/out_ota_bin

Other Notes
~~~~~~~~~~~

For products that support the Identify cluster, you need to set the identify type according to the specific product form:

Implement the corresponding identify command and trigger effect command handlers:

::

    esp_err_t app_identification_cb(identification::callback_type_t type, uint16_t endpoint_id, uint8_t effect_id, uint8_t effect_variant, void *priv_data)
    {
        esp_err_t err = ESP_OK;
        ESP_LOGI(TAG, "Identification type: %d, effect_id: %d", type, effect_id);
        switch (type) {
            case esp_matter::identification::START:
                break;
            case esp_matter::identification::STOP:
                break;
            case esp_matter::identification::EFFECT:
                switch (effect_id) {
                    case (int)Identify::EffectIdentifierEnum::kBlink:
                        break;
                    case (int)Identify::EffectIdentifierEnum::kBreathe:
                        break;
                    case (int)Identify::EffectIdentifierEnum::kOkay:
                        break;
                    case (int)Identify::EffectIdentifierEnum::kChannelChange:
                        break;
                    case (int)Identify::EffectIdentifierEnum::kFinishEffect:
                        break;
                    case (int)Identify::EffectIdentifierEnum::kStopEffect:
                        break;
                    default:
                        break;
                }
                break;
            default:
                err = ESP_FAIL;
                break;
        }
        return err;
    }

Preparation of Files Required for Certification Testing
---------------------------------------------------------

After preparing the device under test, users need to prepare the following files to submit to the testing organization along with the device.

PICS File
~~~~~~~~~~

The PICS file is used to define all Matter features of the product, including endpoints, device types, clusters, attributes, commands, etc. The testing organization will determine the test cases to execute during certification testing based on the PICS file submitted by the user.

The `PICS Tool <https://picstool.csa-iot.org/>`__ website is a tool for opening, modifying, validating, and saving XML format PICS files. `Pics_xml_template_files <https://groups.csa-iot.org/wg/matter-csg/document/40537>`__ contains all PICS file templates, with each XML file defining the feature characteristics of one or more clusters.

The `PICS-generator tool <https://github.com/project-chip/connectedhomeip/tree/master/src/tools/PICS-generator>`__ can generate PICS files based on Pics_xml_template_files. This tool reads the clusters, attributes, commands, features, and events supported by the device under test and outputs a PICS file. Note: This tool cannot automatically generate the Base.xml file, which needs to be opened with PICS TOOL and manually configured. Reference commands are as follows:

::

    # WiFi Device:
    python3 PICSGenerator.py --pics-template path/to/XML_template --pics-output out_folder --commissioning-method ble-wifi \
                            --wifi-ssid ssid-name --wifi-passphrase password --passcode setup-pin-code --discriminator discriminator \
                            --paa-trust-store-path path/to/paa --dm-xml path/to/data_model
    # Thread Device:
    python3 PICSGenerator.py --pics-template path/to/XML_template --pics-output out_folder --commissioning-method ble-thread \
                            --thread-dataset-hex thread_dataset --passcode setup-pin-code --discriminator discriminator \
                            --paa-trust-store-path path/to/paa --dm-xml path/to/data_model

Refer to the documentation: `HowTo - Writing to the DCL.pdf <https://groups.csa-iot.org/wg/members-all/document/27881>`__ .

Other notes for some certification test cases
----------------------------------------------

Route Information Option (RIO) notes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Wi-Fi products using LwIP, TC-SC-4.9 should be tested in order to verify that the product can receive Router Advertisement (RA) message with RIO and add route table that indicates whether the prefix can be reached by way of the router. It can be tested with a Thread Border Router (BR) which sends RA message periodically and a Thread End Device that is used to verify the Wi-Fi product can reach the Thread network via Thread BR. Some Wi-Fi Routers might have the issue that they cannot forward RA message sent by the Thread BR, so please use a Wi-Fi Router that can forward RA message when you are testing TC-SC-4.9.

Here are the steps to set up the Thread BR and Thread End Device. You should prepare 2 Radio Co-Processors (RCP) to set up the `ot-br-posix <https://github.com/openthread/ot-br-posix>`__ and `ot-cli-posix <https://github.com/openthread/openthread/tree/main/examples/apps/cli>`__. The `RCP on ESP32-H2 <https://github.com/espressif/esp-idf/tree/master/examples/openthread/ot_rcp>`__ is suggested to be used here. And you can also use other platforms (such as nrf52840, efr32, etc.) as the RCPs.

Setup Thread BR
^^^^^^^^^^^^^^^^

The otbr-posix can be run on RaspberryPi or Ubuntu machine. Connecting an RCP to the host, the port ``RCP_PORT1`` for it will be ``/dev/ttyUSBX`` or ``/dev/ttyACMX``.

- Build the otbr-posix on the host

::

    git clone https://github.com/openthread/ot-br-posix
    cd ot-br-posix
    ./script/bootstrap
    ./script/setup

Then the otbr-posix will be built and a service named otbr-agent will be created on the host. You can disable the service and start the otbr-posix manually.

::

    sudo systemctl disable otbr-agent.service
    sudo ./build/otbr/src/agent/otbr-agent -I wpan0 -B eth0 -v spinel+hdlc+uart://{RCP_PORT1}

In the above commands:

- ``wpan0`` is the infra network interface. The network interface named wpan0 will be created on the host as the thread network interface.

- ``eth0`` is the backbone network interface, which is always the ethernet or wifi network interface on the host, please ensure that the backbone network interface is connected to the AP which the Wi-Fi product is also connected to.

- ``RCP_PORT1`` is the port of RCP for Thread BR.

The otbr-posix is running on the host now. Open another terminal, start console for otbr-posix, form Thread network, and get dataset.

::

    sudo ot-ctl
    > ifconfig up
    > thread start
    > dataset active -x

Please record the dataset you get with the last command, it will be used by ot-cli-posix to join the BR's network in the next step.

Setup Thread End Device
^^^^^^^^^^^^^^^^^^^^^^^

We use the Posix Thread Command-Line Interface (CLI) as the Thread End Device. Connect another RCP to the host and get the port `RCP_PORT2` for it.

- Build the otcli on the host

::

    git clone --recursive https://github.com/openthread/openthread.git
    cd openthread/
    ./script/bootstrap
    ./bootstrap
    ./script/cmake-build posix
    ./build/posix/src/posix/ot-cli 'spinel+hdlc+uart:///dev/{RCP_PORT2}?uart-baudrate=115200' -v

The console for the ot-cli will be started. Connect the ot-cli to the otbr’s Thread network with the dataset you got in the above step.

::

    > dataset set active <PROVIDE THE DATASET OF THE BR THAT YOU NEED TO JOIN>
    > dataset commit active
    > ifconfig up
    > thread start
    > srp client autostart enable

In the console of ot-cli, discover the product IP address.

::

    > dns service 177AC531F48BE736-0000000000000190 _matter._tcp.default.service.arpa.
    DNS service resolution response for 177AC531F48BE736-0000000000000190 for service _matter._tcp.default.service.arpa.

TC-CNET-3.11
~~~~~~~~~~~~~

No response on step 7 is expected (`Related issue <https://github.com/CHIP-Specifications/chip-test-plans/issues/1947>`__).

All the NetworkCommissioning commands are fail-safe required. If the commands fail with a ``FAILSAFE_REQUIRED`` status code. You need to send ``arm-fail-safe`` command and then send the NetworkCommissioning commands.

TC-RR-1.1
~~~~~~~~~~

For more application endpoints with group cluster, need more nvs size to store group table, so if the ``TC-RR-1.1`` failed, can try to increase the nvs size. (`Related issue <https://github.com/project-chip/connectedhomeip/issues/32481>`__)

Please note that the minimum NVS size required is 48 KB (0xC000) when using a single endpoint with a group cluster.
