Try to print conf->pub_interval in "case MQTT_CLIENT_STATE_PUBLISHING:" in MQTT-client.c to see what interval is set.

Thanks for your reply YiKai Chen

I was print the value of conf->pub_interval in MQTT-client.c.its shows the value of 76800 (600 sec interval).

I try to do the same test and find TCP connection would be disconnected from MQTT server about 200 seconds later. Then, MQTT client would connect to server and send message again. I think this issue is about MQTT keep alive implementation so I suggest you to post an issue on Contiki Github.
