MOSQUITTO Version

Q&A Forum › Category: Raspberry Pi › MOSQUITTO Version

Hi
I have been using version Moquitto v 1.5.7 and ESP32 software based on Module 7.
Now I have installed Moquitto on another RP and it is now v 2.0.11. I can´t get in contact with the broker now. Should I do something else.

Best Regards Håkan

Hi again.

Here are the instructions to make it work.

1) Open an SSH connection with your Raspberry Pi and run the following command:

sudo nano /etc/mosquitto/mosquitto.conf

2) It will open the mosquitto.conf file. Move to the end of the file using the arrow keys and paste the following two lines:

listener 1883

allow_anonymous true

3) Then, press CTRL-X to exit and save the file. Press Y and Enter.

4) Reboot your Raspberry Pi with the following command:

sudo reboot

5) Close putty and open again after a few seconds to run the mosquito broker again.
This time, the ESP should connect to the broker.

Regards,
Sara

Hi
When I install Moquitto according to your instructions I now will get version 2. I have read that this version is not recommended for beginners.
When I try to publish a topic I´m not getting an acknowledgement and I can´t read the topic at the receiver.
Is it possible to change the install routine to get Mosquitto version 1.5 or 1.6 or could I change the publish and subscribe routines?
Best Regards

Hi.
I haven’t tried the new Mosquitto version.
But, in theory, it should work.
When you say you “can’t read the topic at the receiver”, what happens exactly?

Sara

Hi.
I have seen that Mosquitto 2.0 needs some additional configurations to work: https://mosquitto.org/documentation/migrating-to-2-0/
I’ll try it and see if I get it working.
