Broadcast message in Zigbee network

Other Parts Discussed in Thread: Z-STACK

Hello all,

Currently, i am using Z-stack 1.2.0 in my Zigbee network application. I have one coordinator and 3 end-devices.

I am using ZDO_STATE_CHANGE event to monitor End_device status. If end_device out of network, i will turn off a Zigbee's led indication.

I just do a test with broadcast message in Zigbee network with following parameters :

In coordinator :

zclSampleLight_DstAddr.addrMode = (afAddrMode_t)AddrBroadcast;
  zclSampleLight_DstAddr.endPoint = 10;
  zclSampleLight_DstAddr.addr.shortAddr = 0xFFFD;

and using AF_data_request  to send out the message.

In end_device :

set -DRFD_RCVC_ALWAYS_ON=TRUE to enable receive broadcast message.

And i has been successful to send and receive packets through broadcast mechanism.

----------------------------------------------------------------

But, one problem happens in testing.

In End_device, Zigbee's led turn on when end-device has joined to Coordinator, but it does not turn off the Zigbee's led when coordinator shut down (in my debug process, ZDO_STATE_CHANGE event do not trigger when Coordinator go out).

Please help me to solve it.

Thank you very much.

Phuoc.

    When ZC is off and ZED becomes no parent, it won't trigger ZDO_STATE_CHANGE event

    Dear Mr. Yikai Chen,

    Nice to see your support.

    But, please re-check your answer.I want to describe my testing in more detail.

    case 1 : DRFD_RCVC_ALWAYS_ON=FALSE

    when the ZC is off, ZED takes into ZDO_STATE_CHANGE  event and then i check the device type, the Zigbee led is off because it is not in Zigbee network ( it is not END_DEVICE also). And i believe that it goes into this event because the ZC not answer it polling data.

    case 2 : DRFD_RCVC_ALWAYS_ON=TRUE

    when the ZC is off, ZED does not takes into ZDO_STATE_CHANGE  event, the Zigbee  led is not off.  And i can't explain what is exactly phenomenon. 

    Please take a look and help me to solve it.

    Thanks.

    Phuoc.
