    Hi yk chen

    Actually These sensors are doesn't have poll control cluster so we not able to get  the check-in Interval we not able to get the polling rate.

    Hi Giribabu,

    Yikai Chen is not asking about the poll control cluster but rather the POLL_RATE determined from SysConfig.  If a ZED child does not check in at the rate as set by NWK_END_DEV_TIMEOUT_DEFAULT or determined by END_DEV_TIMEOUT_VALUE then it will be aged out by the ZC/ZR parent.  You can create a custom application to inquire or calculate this poll rate but it cannot be discovered using the default Z-Stack.  As you have no way of waking the ZED you will have to queue the message until the ZED sends a data request or disable sleep on the ZED.

    Regards,
    Ryan

    If those devices are previous Zigbee HA profile devices, they might not support polling control. If you need poll control cluster support on devices, I suppose you should contact manufacturer to revise firmware.

    Hi  Yikai Chen and Ryan

    Actually Device is Sending Data request in every 300 seconds.

    In code under zstackserverznp  f8wConfig.h file .For End Device following are defined.

    RFD_RCVC_ALWAYS_ON FALSE

    POLL_RATE 1000

    Do I need to change these values to change the poll rate of the device?

    If those device doesn’t support poll controller cluster, it’s not possible to change polling rate remotely from coordinator.

    The macros described affect the local device, so they would only apply to the ZED which is asleep and polling.  The situation is as YK stated.

    Hi Ryan and yikai

    Do we have any other way to know the sleepy end devices network status,sending woke up request to the Device?.
    Actually  Data Requests  are coming from Device we able to see in sniffer.
    How we can know this are reaching NPI server?

    We are using  TI CC26x2R1 as  sniffer  Receiving  Packets through Ti SmartRF sniffer agent 2 with Wire shark in Windows,How does it possible to use in Ubuntu?

    There’s no application callback to notify parent node that it receives data request. The only solution is poll control cluster support so it’s better for you to contact manufacturer to add poll control cluster.

    PACKET-SNIFFER is only known to be supported in Windows and is not tested with Linux environments.

    Hi Ryan,

    How can we enable or implement the callback function to handle the data requests.? and where we have to enable data requests( i.e in  ZNP firmware, NPI,zstack).

    Data request is handled by Z-Stack library and no application callback or event for developers to process it.
