Dear Susheel,

Thank you for the explanation. Sorry for my late response. I have realized the last thing you said and changed the time interval of led blink. That way it worked like charm but I am not sure if it interferes any feature in the background. I am very grateful. Have a nice day.

Hi,

you please give us more information on what is meant by the kit does not respond?

Do the mqtt_connect API result in failure, or can you check with a breakpoint if the function is very called?

The approach seems right as well. However, there is little information available on symptoms,

Also, if we could sniff traffic on the router, that could be good. And here, sniff need not imply BLE sniffer, but a local interface dump could do as well.

Also note that after the IP interface is up, getting an actual IPv6 global address takes some time due to a procedure for SLAAC.

Actually, I have not changed many things from SDK. It is almost the same with its original version. In SDK, the mqtt status is changed by pressing button. However, I want that when clients connect to the router, and ipv6 interface is up, the mqtt connection will be done automatically. I have tried that but clients did not respond to that.

Hi,

I think your query will be more informative if you attach some code snippets of what you are doing. For example when the button handling . I am no expert in MQTT but i would recommend you to add some code snippets to get more help from the forum.

By saying after IPv6 interface is up I meant buttonless mqtt connection of clients
