hi. I install mosquitto is server for pi3
install paho mqtt python for pi 3
my problem :
I publish data from esp8266 to pi3,when pi3 receive data then pi 3 publish " OK " for esp8266
program for esp8266:
------connect_mqtt_pi3
------publish_data
------receive_feedback
------exit
I see pi3 receive data receive and publish "OK" but esp8266 not receive "OK"
when I write:
------connect_mqtt_pi3
------publish_data
------receive_feedback
------publish_data
------receive_feedback
------exit
then esp8266 receive "OK" 1 times
Why do I have to send 2 times to get feedback?

Turning on debug on the broker to show the packets sent and received might help you understand what is going on.
