How can I differentiate a node from another node as node address is dynamic

When a device joins network, there is a end node announcement with its short address. You should keep that and use it.

Which function will process that announcement? But address is not enough to know which device I am talking to, its name is also necessary.

Please point me to the code where this announcement  from the device is processed.

Thanks

You can register it by "ZDO_RegisterForZDOMsg(task_id, Device_annce);" in your init function and process "case Device_annce:" in XXX_ProcessZDOMsgs. By the way, you said " its name is also necessary." but I have no idea about name of zigbee device. How do you give a name to device?

Dear YiKai,

I have done the following highlighted change in my code...

void zclSampleHCUnit_ProcessZDOMsgs( zdoIncomingMsg_t *inMsg )

{

ZDO_DeviceAnnce_t devAnnce;
switch ( inMsg->clusterID )
{
case End_Device_Bind_rsp:
if ( ZDO_ParseBindRsp( inMsg ) == ZSuccess )
{
// Light LED
HalLedSet( HAL_LED_4, HAL_LED_MODE_ON );
}
#if defined(BLINK_LEDS)
else
{
// Flash LED to show failure
HalLedSet ( HAL_LED_4, HAL_LED_MODE_FLASH );
}
#endif
break;

case Match_Desc_rsp:
{
ZDO_ActiveEndpointRsp_t *pRsp = ZDO_ParseEPListRsp( inMsg );
if ( pRsp )
{
if ( pRsp->status == ZSuccess && pRsp->cnt )
{
//zclSampleThermostat_DstAddr.addrMode = (afAddrMode_t)Addr16Bit;
//zclSampleThermostat_DstAddr.addr.shortAddr = pRsp->nwkAddr;
// Take the first endpoint, Can be changed to search through endpoints
//zclSampleThermostat_DstAddr.endPoint = pRsp->epList[0];

zclHCUnit_DstThermostatAddr.addrMode = (afAddrMode_t)Addr16Bit;
zclHCUnit_DstThermostatAddr.addr.shortAddr = pRsp->nwkAddr;
// Take the first endpoint, Can be changed to search through endpoints
zclHCUnit_DstThermostatAddr.endPoint = pRsp->epList[0];

// Light LED
HalLedSet( HAL_LED_4, HAL_LED_MODE_ON );
}
osal_mem_free( pRsp );
}
}
break;

case Device_annce:
{
ZDO_ParseDeviceAnnce( inMsg, &devAnnce );
}
break;

default:
break;
}
}

But for example if I have one coordinator B1 and have node B2 to measure the Temperature value send it to B1. I also have two more nodes B3 and B4 which are used to control the heater and cooler respectively.

If temp < 20 C then I would like to send a command to switch on the heater to B3 and if the temperature is > 30 C I would like to send command to switch on the cooler then how can I differentiate B3 and B4.

If I know the address of both of them what is the way it is connected to the heater or cooler?

I mean the Device name can be sent using an application message using the AF_DataRequest() function. I got the reference from the GenericApp for sending "Hello World" message.

Thanks

How to differentiate B3 and B4? This is about device management of automation and nothing to do with zigbee spec. You need to do that on your application. My suggestion approach is :

When you get a new end node announcement from B3, specify it as heater and keep its short address. On the contrary, specify B4 as cooler and also keep its short address. Then, apply the control rules: If temp < 20 C then I would like to send a command to switch on the heater to B3 and if the temperature is > 30 C.

YiKai,

Unfortunately I am not receiving the Device_annce notification from the SampleLight node to the Coordinator (SampleHCUnit). Is the ZDO_AddrChangeIndicationCB() responsible to send the announcement ot Coordinator. But I found it is not called anywhere in the code. Where to call this function from SampleLight node, if this is the correct function?

Thanks

Do you register Device_annce by "ZDO_RegisterForZDOMsg(task_id, Device_annce);" in your init function?

Yes, I did in HCUnit only.

Try to enable packet sniffer and restart your end device. Check if your device send end node announcement in sniffer first.

I will check the sniffer log, but if it does not send what to do?

Thanks

It should send end node announcement  because it is handled by zstack.

Dear YiKai,

I found some short address association status message in the sniffer log, is it the Device announce message. Please find attached the log file.

I go the Device_annce now

Can I add the following code under case Device_Annce to bind the Coordinator with the recently joined node so that I can control light with using the SW2 and SW4 presses?

ZDO_ParseDeviceAnnce( inMsg, &devAnnce );
MyAddress = devAnnce.nwkAddr;

// Initiate an End Device Bind Request, this bind request will
// only use a cluster list that is important to binding.
dstAddr.addrMode = afAddr16Bit;
dstAddr.addr.shortAddr = 0; // Coordinator makes the match
ZDP_EndDeviceBindReq( &dstAddr, NLME_GetShortAddr(),
SAMPLEHCUNIT_ENDPOINT,
ZCL_HA_PROFILE_ID,
ZCLSampleHCUnit_BINDING_INLIST, bindingInClusters,
ZCLSampleHCUnit_BINDING_OUTLIST, bindingOutClusters,
TRUE );


// Send config report command to the thermostat
zclCfgReportCmd_t cfgRptCmd;
cfgRptCmd.numAttr = 1;
cfgRptCmd.attrList[0].direction = 0;
cfgRptCmd.attrList[0].attrID = ATTRID_HVAC_THERMOSTAT_LOCAL_TEMPERATURE;
cfgRptCmd.attrList[0].dataType = ZCL_DATATYPE_INT16;
cfgRptCmd.attrList[0].minReportInt = 5;
cfgRptCmd.attrList[0].maxReportInt = 10;
cfgRptCmd.attrList[0].timeoutPeriod = 0;
cfgRptCmd.attrList[0].reportableChange = NULL;

zcl_SendConfigReportCmd(SAMPLEHCUNIT_ENDPOINT,
&zclHCUnit_DstThermostatAddr,
ZCL_CLUSTER_ID_HVAC_THERMOSTAT,
&cfgRptCmd,
ZCL_FRAME_CLIENT_SERVER_DIR,
0, 1);

// Send config report command to the humidity sensor
cfgRptCmd.numAttr = 1;
cfgRptCmd.attrList[0].direction = 0;
cfgRptCmd.attrList[0].attrID = ATTRID_MS_RELATIVE_HUMIDITY_MEASURED_VALUE;
cfgRptCmd.attrList[0].dataType = ZCL_DATATYPE_UINT16;
cfgRptCmd.attrList[0].minReportInt = 5;
cfgRptCmd.attrList[0].maxReportInt = 10;
cfgRptCmd.attrList[0].timeoutPeriod = 0;
cfgRptCmd.attrList[0].reportableChange = NULL;

zcl_SendConfigReportCmd(SAMPLEHCUNIT_ENDPOINT,
&zclHCUnit_DstThermostatAddr,
ZCL_CLUSTER_ID_MS_RELATIVE_HUMIDITY,
&cfgRptCmd,
ZCL_FRAME_CLIENT_SERVER_DIR,
0, 1);

// Send config report command to the light on/off
cfgRptCmd.numAttr = 1;
cfgRptCmd.attrList[0].direction = 0;
cfgRptCmd.attrList[0].attrID = ATTRID_ON_OFF;
cfgRptCmd.attrList[0].dataType = ZCL_DATATYPE_UINT8;

cfgRptCmd.attrList[0].maxReportInt = 50;

ZCL_FRAME_CLIENT_SERVER_DIR,

// Initiate a Match Description Request (Service Discovery)
dstAddr.addrMode = AddrBroadcast;
dstAddr.addr.shortAddr = NWK_BROADCAST_SHORTADDR;
ZDP_MatchDescReq( &dstAddr, NWK_BROADCAST_SHORTADDR,
ZCL_HA_PROFILE_ID,
ZCLSampleHCUnit_BINDING_OUTLIST, bindingOutClusters,
ZCLSampleHCUnit_BINDING_INLIST, bindingInClusters, // No incoming clusters to bind
FALSE );

Thanks

Yes, it is the Device announce message and good to hear that you get the end node announcement. If you want to bind the coordinator with the latest joined device, you should use ZDP_BindReq, not ZDP_EndDeviceBindReq and ZDP_MatchDescReq.

You mean I shall send ZDP_BindReq and ZDP_MatchDescReq.

I have two nodes, one with THERMOSTAT and HUMIDITY SENSOR clusters and other with SAMPLELIGHT ON/OFF cluster. How I will differentiate them with the Device announcement?

What will be the difference in sending the messages to both the nodes?

When I am using Samplelight and Coordinator it is working but when I replace the Samplelight with Thermostat node it doesn't work with the node as expected ( I am not receiving the temperature and humidity periodically).

What can be the problem?

Thanks

1. No, I mean you should use ZDP_BindReq only in your case.

2. When you receive end node announcement, you should use ZDP_SimpleDescReq to ask for simple description of it. The simple description of device will show you the device information such as profile ID, device ID, endpoint, and supported clusters.

3. When you replace the Samplelight with Thermostat node, you need to put ON/OFF cluster support into Thermostat.

1. ok. 

2. I will try this

3. I mean sample light is not functionally replaced with Thermostat, as I have only two ZigBee nodes and need to test for three nodes I am overwriting the Samplelight program with the Thermostat program to the same node. If I test these functionalities individually it works fine. But when I overwrite it with another while keeping the Coordinator on, does not receive the temperature and humidity updates to the Coordinator.

Thanks

I don't understand what you mean to overwrite it with another while keeping the Coordinator on. It sounds weird.

I have only two devices I need to have a Coordinator, one node for Temperature and Humidity measurement and another for switching on a relay when Coordinator sends a command. Sensor node reports the sensor data periodically to Coordinator.

But when I would like to test the sensor node I will program the sensor interfacing code into that node, when I would like to use it to switch on/off relay I will program the relay on/off code into that. I don't want both relay and sensor functionality in the same node.

But when I flash the relay on/off code into the node it works but when I flash again the sensor code into the same node, coordinator is not receiving any updates from the sensor node.

Please let me know how to solve this problem.

Thanks

Dear Kumar Singh,

I am very sorry for the late response, but I have done it long back. Now I don't even remember what I did to fix the issue.

But if I recollect the same I will definitely forward you the same without fail.

Please apologize me for not able to help you.

Thanks,

Raghu Devisetti

Dear Kumar Singh,

Please find below some code which may have the logic you are looking for but I am not still sure if it is there. But there is definitely a chance you may get it.

Wish you all the best.
