I’m do all exactly as you wrote:
Rui Santos explain
My goal is to see – is ESP32 correct send packages to server?
cloudmqtt have a simple user interface to see arrived data.
I’m use your example from ESP32 course:MQTT Project – MQTT Client ESP32 #1
and add string to code (with correct user and password):
But I don’t see any information from cloudmqtt.com web interface.
Is it correct ?
I’ve never used that CloudMQTT feature, but I think you need to enter the topic name in the “Received messages” field. so CloudMQTT is subscribed to the topic that your ESP32 is publishing the messages and it can receive them.
Can you type in the field the topic that the ESP32 is publishing messaged?
Let me know your results.
I’m don’t know what happens earlier, but I’m check settings again, run project and see messages from ESP32 in CloudMQTT Websocket UI!
P.S. Websocket UI interface show all incoming message, you don’t need to type anything.
