MQTT Connection hanging on

[mic9119]

Hello,

I downloaded before 4 days all files and programmed my ESP.

I Have installed Mosquitto Broker on my PC. I added the user from the ESP. The Server IP is the IP from my PC. But on TeraTerm my ESP say "Connecting to MQTT..."

The Mosquitto Broker is running. I tested this with MQTT.fx an MQTT Explorer.

Can you help me?

Best regards

Hi, please try this. go to the webgui go to settings and check your mqtt settings and re-enter the password and then press save. if the issue persist uncomment this 3 lines and flash it again.

src/main.cpp: In function 'void onMqttConnect(bool)':
src/main.cpp:683:35: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]
sendDebug("ResetReason", val);

sendDebug();
^
src/main.cpp:402:6: note: declared here
void sendDebug(char *key, String value)

There are errors

[14yannick]

Replace this line with sendDebug("engineMes",hoermannEngine->state->debugMessage);
Also move it one line up before the line
hoermannEngine->state->clearDebug();

I get this Info via serial Monitor:

Ok please send the terminal output of the build command to see the version of libraries used for build

[14yannick]

Is your esp connected to the wifi? Or are you connected to it with the wifi access point

do you mean this?

The esp ist connectet to the wifi

[14yannick]

try to change the libs in platformio.ini with this

lib_deps =

I get the same log...

[14yannick]

start an neu platformio console

and type pio pkg uninstall and after pio pkg install
Your build should look like something like this ````

AsyncMqtt is very old
ghostl is there a difference?
home-assistang is lost
AsyncTCP is there a difference?

[14yannick]

|-- home-assistant-integration @ 2.0.0 is normal as I'm looking if we can replace the mqtt librarie with it. Have you change your libs dependency as written here.

Now it looks like the dependencys from you
But the los is always the same

[mic9119]

Hey,
is there anything that i can do for you to find any mistake?
