MQTT messages opening too many TCP connections on Websockets in React

Why does this MQTT client works fine through MicroPython's webREPL but fails in the main.py of the ESP32?

QUESTION

MQTT messages opening too many TCP connections on Websockets in React

Asked 2021-Mar-17 at 06:10

I have a ESP32 device sending data at a very fast rate using umqtt module. Also, a Mosquitto broker listening on ports 1883 for mqtt and 9001 for websockets. Finally, a react App showing messages in real-time.

The problem is that every time the React App receives a message from the ESP device, a new TCP connection is established, resulting in a lot of opened connections, as you can see here:

It was solved after moving all the mqtt logic constants into the useEffect. Now it updates the state after every received message and does not keep the connection open.

Why does this MQTT client works fine through MicroPython's webREPL but fails in the main.py of the ESP32?

Asked 2020-Dec-31 at 22:24

I'm currently working an IOT project requiring the transfer of sensor data between an ESP32 (a wESP32 to be exact) and a Raspberry Pi configured as a broker. From what I've read so far the MQTT protocol seems to fit my needs perfectly, I'm thus running a Mosquitto broker on the Pi as well as the MQTT simple client library provided on the micropython's GitHub repository.

The first tests performed in the MicroPython WebREPL have been successful as I've been able to receive data published from the ESP using the following code:

Thanks for your help Reilly, The way I solved it is as follow. With a bit more understanding of mqtt and micropython I found that the only thing that happens when you try to install umqtt simple and umqtt robust,is that it makes in de lib directory of your wemos a new directory umqtt. Inside this directory it installs two files robust.py and simple.py. While trying to install them I kept having error messages. But I found a GitHub page for these two files, so I copied these files. Made the umqtt directory within the lib directory and in this umqtt directory I pasted the two copied files. Now I can use mqtt on my wemos.
