Matter certification process

1. Introduction

One of the key features of the Matter protocol is that its software code is open source, which means that anyone can develop devices that are compatible with it. However, in order to ensure that these devices are fully compliant with the Matter standard and support all of its security mechanisms, they must be certified by the Connectivity Standards Alliance (CSA).
The certification process involves testing and validation by a third-party testing lab to ensure that the device meets all the necessary hardware and software requirements for full compliance with the Matter standard. Only devices that have received official certification from the CSA are allowed to carry the Matter logo.

2. Matter certification types

CSA defines two types of certification:

  • Matter HW solution
    • Matter HW solution certification includes whole Matter SW and underlying Transport layer (Thread/BLE)
    • That is the certification we are targeting with a dynamic concurrent mode BLE/Thread MTD
  • Matter SW component
    • Matter SW component certification only includes a subset of Matter HW solution and is only applicable to Software Components that run within the context of a Supported Operating Environment (SOE).
      SOE shall support, at minimum, all the mandatory requirements for a Matter Software Component.

3. Matter certification process

Similar to Zigbee and Thread certifications, Matter certification is preceded by an in-house testing phase. Each company that intent to get certification should test its product using the CSA provided Test Harness.
The list of Authorized Test Providers can be found on the CSA website. Processing: Application Review

Products with Thread, Wi-Fi, or Bluetooth need certification according to relevant standards. In our case, STMicroelectronics is in the process of certifying a Matter Thread HW solution, so we must:

  • certify Bluetooth
  • certify Thread with Thread Group
  • certify Matter with CSA
