CC1352P: How to detect ZC was down in ZR?

Part Number: CC1352P

Hi,

Good morning.

A ZigBee network works well with 20 ZRs, the power of ZC  was off by accident, is it possible to detect the ZC was down in ZR and which MT command could be used to?

Best regards,

David

    Hi David,

    Given the mesh network capabilities and healing properties of the Zigbee protocol, it is possible for the ZC to not be directly associated with certain ZR nodes.  Thus there may be no information locally available, or the routing table could be outdated, and you will need to send ZDO packets to the ZC to verify that a valid response is returned.  For example, you could use ZDO_IEEE_ADDR_REQ or ZDO_MGMT_LQI_REQ (among others) with the ZC's short address (0x0000) set as the destination and await the ZDO_NWK_ADDR_RSP or ZDO_MGMT_LQI_RSP.  Alternatively, if an error comes back that no route was found (ZNwkNoRoute) then you could try a ZDO_MGMT_RTG_REQ as the last resort, and a failed response to this request would confirm that no ZRs can provide a path to the ZC.

    Regards,
