CC2530: Simple binding of a switch and a light

Which Z-Stack version do you use? For your reference, SampleLight and SampleSwitch in Z-Stack 3.0.2 would automatically binding to each other in BDB commission.

Thank you for very quick response, YiKai Chen. Yes, I'm using Z-Stack 3.0.2.

Indeed, I can see SampleSwitch sending genOnOff commands, but how does the command reach the right target device (the one with my SampleLight firmware)? I can't see any explicit addressing in the code.

Thanks Ryan. So I want to use the binding table. I'm configuring it with Zigbee2MQTT like this:

But then toggling the endpoint on SampleSwitch does not toggle the one on SampleLight.

Are the sample apps missing anything in the code?

I'm not experienced with the Zigbee2MQTT solution and recommend that you ask questions on their forum.  Toggling an attribute for the local SampleSwitch is not the same as sending a command to toggle the remote SampleLight's attribute.  That's not how Zigbee binding is intended to operate.

I took a look at the sample that you sent over. They are building the binding table by taking the address of the first device that happens to join the network. I need to do it in a more controlled, standard way.

Are there any standard bind request commands that my app should handle in order to build the table? Hopefully they are what Zigbee2MQTT sends when I define a binding there.

The example takes the address of the first device since it is a proof of concept demonstration only.  You should further develop your application in whichever way you determine necessary.

You can send a ZDP_BindReq for your application or use ZDO_BIND_REQ for host device MT commands communicating with a ZNP, provided that is the interface required for the Zigbee2MQTT.

Thank you for your continued support. Are there any samples / tutorials that could cover that?

I'm not sure what you're specifically referring to.  Here is the Z-Stack Monitor and Test API for further reference, also found in Z-Stack 3.0.2\Documents\API\Z-Stack Monitor and Test API.pdf.  As mentioned before, it's best to talk with Zigbee2MQTT experts if you're using their application.

What I was asking is if there are any sample apps that demonstrate this end-to-end: the handling of the ZDO_BIND_REQ, population of the binding table, and then leveraging the table for direct communication between the bound devices and for reporting.

Maybe try to refer to www.cnblogs.com/.../2032487.html

Thanks, YiKai, this article seems to be exactly what I'm looking for, but it looks extremely gibberish due to inaccurate translation and formatting, and I can't really follow it. Do you think you could find something of higher quality?

Those information can also be found inside Zigbee specification.

I'd like to leverage as much of the existing Z-Stack code as possible, thus I don't want to end up following the specification and implementing the code myself. That's why I'm looking for a sample app that could show how much I need to code myself, and how much is already there.

Z-Stack provide related APIs but not all examples of binding method. You have to implement it by yourself.

Okay, so which APIs should I use? Which compiler flags to enable?
