8.2 Bidirectional Commissioning

  • For bidirectional commissioning, the sink device is put in Commissioning mode, and GPD sends a Commissioning command with RxAfterTx-1 (see packet #145) and all device details including the device type, security level, security key type, security key and more.
  • The sink device verifies the details and responds with Commissioning Reply (see packets #146 and #147). Commissioning Reply can include a new security key and PAN ID if the same are requested in the commissioning packet.
  • When GPD receives and processes this Commissioning Reply, it sends a Success command with a new key and PAN ID (see packet #150). On successfully decrypting packet #150 (Success) from GPD, the sink device adds a new entry in its sink table, broadcasts GP pairing and device announce for this device. For more details, refer to the Zigbee PRO Green Power feature specification Basic functionality set (Version 1.1.1).
