NRF 52840 matter window covering accessory is displaying no response on Apple Home app with Home pop mini

[danny_zhang]

Hi

 I use a HomePod mini as a border router,commissioning six window covering samples.They are working normally.But after two days,I found two samples displaying no response on the Apple    HOME app.Must be added again.And then I found when I power off the samples for a while,they are displaying no response after power on.I've been waiting for a long time, and the app still shows the same thing.

 NCS Version: v2.3.0

 Home pop mini version:16.4

How should I debug this issue,

Regards

Danny

Hi,

Are you using our window covering sample with the default configuration, meaning that the SSED support is enabled? Are they planning to use this feature? Do you see the same problem if SSED support turned off?

Can you please provide us with the .pcap file from the sniffer trace? Make sure you perform the sniffer trace on the correct channel. You should be able to get the channel from the serial terminal after commissioning to your ecosystem, by entering the command "ot channel". If you can also provide the networkkey, that would enable us to read the sniffer trace correctly (you can send the info to me in a private message to avoid publishing in public thread):

uart:~$ ot channel
11
Done
uart:~$ ot networkkey
00112233445566778899aabbccddeeff
Done

Best regards,
Jørgen

Hi,

I use the default configuration,SSED is enabled.Yesterday, I went to the agent to reproduce this issue. The nrf52840dk board burned the window covering routine, added the device to the HOME app, shut it down for 2 minutes, and then turned it on again. The problem also reappeared. At present, due to the thread sniffer not working properly, it is still unable to capture packets.Home pop mini'sversion is 16.4.

Best regards,

Danny

Hi,

Out Matter team needs a sniffer trace to understand what happens and help resolve this issue. Can you elaborate more on what is not working with the sniffer trace? 

Have you made sure that you start the sniffer on the correct channel used by the device after being commissioned into the Apple HomePod Mini ecosystem?

I see there is a filter applied in you image from the sniffer log, have you tried removing this?

If you are not able to get the sniffer running on your current setup, could you try to set it up on a different computer, carefully following all the steps in the user guide to set it up?

Best regards,
Jørgen
