Disconnected from MQTT server

[js903801]

Hello, my original ESP RFID Relay board sporadically loses the connection to the MQTT server and does not reconnect automatically. Only after a reset is the MQTT will connect again. I read that I should use the version 0.8, here is the same problem. Just like the version 1.2. What can I do?

Can you please share mqtt logs?

[omersiar]

MQTT Code should be revised. #256

Changing line:142 in main.cpp to unsigned long interval = 55;
works for me!

Great work btw.
Regards.

Interesting, this shouldn't be problem unless there are some rate limits on the server side. Thank you for sharing

How can I adjust that? Is an Upadate planned? I also have the problem.

Compiling the dev version seems to fix the issue!
I can provide a bin file when i get home.

The bin file is here:

I also added : SPI.setClockDivider(SPI_CLOCK_DIV8);
wich helps with longer cables.. mine is approx. 1m

This solution worked for me. In v1.3.3 this problem was still there and caused a lot of mqtt disconnections.

[LEJOUI]

Seems I was too early. Still having disconnected from mqtt after a few hours.

For now, I'm testing this solution in v1.3.3, coming back with results..

[cyberhasse]

I bought a new router and after that the problem is better.
Regards.

Yes, still no luck over here.. It would be nice that after a drop in wifi or tcp disconnected there would be a few attempts to try to connect to the mqtt server again, or a setting that when tcp disconnects a restart will take place. For now my solution is to disable wifi after x minutes so it reconnects to my mqtt server again. Downside is that i've to scan the tag twice after a long time not in use.

Also on v1.3.3 and I'm getting MQTT disconnected after a few hours. For now I've set it to reboot every 24 hours but still not a solution since it disconnects after 3 - 4 hours.

Anyone worked any possible solution for this?

Hello and good Day to you All.
I have the Same Problem. I had esp rfid (actual ver 1.3.1) on a Node mcu and use it to control several Things over mqtt and IOBROKER. But After different time the mqtt Connection is closed. In the log file i could read:

WARN mqtt Disconnected from MQTT server
Additional Data TCP_DISCONNECTED

No wlan issues and no wlan disconnections. Just the mqtt Connection is closing. Every other mqtt Client is still connected with the mqtt IOBROKER Server.
After a reboot of the esp rfid it establish the Connection again for sometimes hours or sometimes 1 Day...
So i hope you can help me fixing this issue.
