52840 ZIGBEE coordinator can not get Math Descriptor Request package in app

[hank@wy]

Hi,

    I use nordir 52840 as zigbee corrdinator, but one zigbee device send math descriptor request package, I can not get the information in application process. How can I get the package and process it to add the device in the corrdinator network?

Hi,

I didn't quite understand the question. Are you trying to send a match descriptor request from the nRF52840 coordinator to a device but the device does not send a response?

[hank@wy]

The device send a match descriptor request, and nRF52840 coordinator can not get the package in application, so I can not process the package with a response.

 the question is : How to get the device's match descriptor request package.

Hi,

Is the third party device and the coordinator in the same network (same network panid)? Have you implemented the IAS zone output cluster in your coordinator? Have you implemented your own coordinator or are you using our Zigbee CLI example from the SDK as a coordinator? Because the CLI example does not have a IAS zone cluster implemented.

The response for the match descriptor request is sent by the stack automatically if there is an endpoint that matches the query from the match descriptor request, if not the coordinator will not sent a response.

 3. I had tried zigbee CLI example, it also can not work.

 4. I add a picture after, the device's short ID is : 0x41f8

Hi,

What exactly do you want the third party device to do? Can you be more specific about your problem? What kind of device is the third party device you are using? Do you have problems joining it to your coordinator network?

The thing is that if you are sending a match descriptor request looking for IAS zone output cluster, then only the devies with an IAS zone output cluster will response.

What do you expect to happen after the match descriptor response is sent? Do you want to interact with the third party devices somehow?

You can find more information about the IAS zone cluster in the infocenter and also I recommend reading the information about the cluster in the ZCL spec.
