MQTT disconnects while displayText about md_parola

[MajicDesigns]

Animate() takes a few milliseconds to run if it has to animate, so I don't expect that that should stop MQTT from running. If it is dropping connection because in that brief time, then there is not much to do about this as the animation needs to run somehow.

I would be more likely that your code (which is unseen) is not calling the whatever MQTT needs for maintaining the connection, or you are somehow exceeding the watchdog timer for the ESP8266.

Thanks for the quick reply.

Here is the code: https://github.com/debsahu/Scrolling-Text-Home-Assistant/blob/master/Scrolling_Text_Home_Assistant/Scrolling_Text_Home_Assistant.ino

I agree that Animate() takes some time, but is there a way to insert "mqtt.loop(); yield();" in some way while animating? Just point me to where in library that I need to change.

[MajicDesigns]

The point is that animate() by itself takes almost no time at all, so the problem is more likely somewhere else in your code.

I would expect that "client.loop(); yield();" should be performed EVERY TIME through loop(), not just as an 'else' condition. They work the same way that animate() does - they need to be called as often as possible.

While MQTT connection is maintained, "client.loop(); yield();" is done. If it disconnects, it tries to reconnect. This is the non-blocking MQTT implementation, even with this it fails. And I already have them outside the animation loop as well.

[MajicDesigns]

I still think your structure for calling the yield() and client.loop() methods is wrong, but I am not writing your code.

Then you will just have to try different things until it works. Changing all the animations to PRINT will be a start, as these finish in 1 cycle (a few milliseconds).

I figured out the WiFi & MQTT dropouts. The analogread needs a delay which I did not include. This is no fault of MD_Parola, please close this (non)-issue.

ok. Good to hear you fixed your problem.
