HELP！I can't get responsed while using homekit adk

[moculll]

As you can see above, this is the normal case, It works ,and the apple home can control the device well
and when I add a few more services, the ot bufferinfo shows like this:

maybe is the coap overflow or something.....? I don't know, I've tried adding CONFIG_OPENTHREAD_CUSTOM_PARAMETERS=" OPENTHREAD_CONFIG_COAP_BLOCKWISE_TRANSFER_ENABLE=1 OPENTHREAD_CONFIG_MESSAGE_BUFFER_SIZE=138" to my project, but nothing changed, what I can make sure is that adding services will cause this problem, please help me T T

It appears that the CoAP component is holding on to messages. Note that CoAP normally buffers confirmable messages to properly match responses. It could be that the device is not receiving CoAP responses, or at least not at the rate that it is trying to send requests.

Unfortunately, I don't have visibility into how the HomeKit ADK leverages CoAP. I would reach out to Apple or whoever provided you the HomeKit ADK for more information.
