Revision as of 14:29, 10 October 2023 by Registered User

1. Introduction

Thread Certification is important for ensuring security, reliability, interoperability, consumer confidence, and market access for devices that use the Thread protocol. There are two types of certification:

  • Full Thread Device certification (FTD)
    • Every Thread role is supported but Border Router
  • Minimum Thread Device certification (MTD)
    • Only End Device / Sleepy End Device roles are supported

802.15.4 PHY certification has to be performed before Thread stack certification.

  • Thread certification is performed using GRL Tool.
  • Various golden devices are used :
    • Nordic Thread Device - nRF52840-Dongle
    • Silicon Labs Thread Device - XG12-DK4166C (SLTB004A/C)
    • Raspberry Pi - Model 3B or 4B
    • Kirale USB dongle - KTDG102
    • Kirale Border Router - KTBRN1
  • Fully automated test bench
  • Up to 33 devices are used to form Thread Mesh network (TC Leader 5.2.3)
  • GRL Tool is available to Thread Group Member
    • Certification tests can be run at ST premise before going to the test house.
