I'm going to send the data("ABC") fome samplethermostat(coordinator) to sampletemperaturesensor, I added the marked code to the thermostat.

it's true ?

You should use unicast instead of broadcast when sending message and you should create your own ZCL cluster/attribute to send data instead of using AF_DataRequest directly since you are using samplethermostat which is based on Zigbee HA/ZCL.

tnx, how create my own ZCL cluster/attribute?
for send data from sampletemperaturesensor to samplethermostat,is it the same way?

I suppose you can use thermostats and temperature clusters but create your own attributes. It’s the same to send data from sampletemperaturesensor to samplethermostat.

Can you make a simple example?

Also see Part 2 of the following: dev.ti.com/.../zigbee_03_fundamentals.html

It shows how to send raw data packets over-the-air.

tnx but why can not I use AF_DataRequest?
this link send data with AF_DataRequest.

2.What is the command used to send the Temperature by sampletemperature?
3.Why should the command of sending the temperature different with the command of sending the data?

1. You can use AF_DataRequest. However, please note that you are using 0x0000 as the cluster ID, yet this is defined as the cluster ID of the Basic cluster. This may result in unexpected behavior.
It may be better to use the zcl functions to send ZCL data packets, since the zcl will fill in the appropriate fields in the command.

2. Please see the function zclSampleTemperatureSensor_SendTemp.

3. The Temperature Measurement cluster has attributes as defined in the Zigbee Cluster Library (ZCL). When a device receives a message and identifies the cluster ID, then it will expect those attributes which are defined for that cluster in the ZCL.
For example, if a device receives a report from Temperature Measurement cluster (with ID ZCL_CLUSTER_ID_MS_TEMPERATURE_MEASUREMENT), then it would expect to find the TemperatureMeasurement reportable attribute (ATTRID_MS_TEMPERATURE_MEASURED_VALUE). The Zigbee Cluster Library will explain what those attributes mean.

Thank you for the complete explanation,
Because I am a beginner, so I do not understand the references you gave me.please to send the data with the function zcl, send me an example.
