[BUG]Temperature and Position not Updating Despite Working Serial Comms

[retromaster]

Describe the bug

Upon startup, the ESP3D web interface is stuck at "waiting for temperatures list". I am sure, however that the serial comms between the ESP module and the printer is fine because the printer is responding well to the commands I enter in the Terminal panel. For example, I enter M503 and I am able to get the whole settings report and there does not seem to be any data corruption. Even better, I send the M105 command and get back the temperature readings, at which stage the Temperature and Extruder panels update themselves with the data. However, they do not continue updating automatically. Another thing, the Settings > Marlin panel also seems to work fine.

To Reproduce

Issue manifests itself right at startup.

Expected behavior

I expect the web UI to display the temperatures and position on startup and continue updating them.

ESP3D Firmware:

• ESP3D FW version: [3.0.0.8b1] (Downloaded latest branch as ZIP from github).
• ESP3D-WebUI Version: [3.0.0-4b1.M2.1]
• Wifi mode: STA (Client)
• Flash method: PlatformIO

Target Firmware:

Marlin 2.1.2.5 (with some modifications for Anycubic 4MAX Pro support).

**Board used **

ESP Board: NodeMCU v3 (ESP8266 w/ 4MB Flash).

Additional context

This may very well be some kind of configuration issue, it seems like something simple that I may have missed. If not, is there some kind of serial comm log accessible via the ESP3D-WebUI? Perhaps I could use that to diagnose the problem.

did you enabled the polling commands in webui interface settings ? https://esp3d.io/ESP3D-WebUI/Version_3.X/documentation/polling/

After enabling the "Polling Commands" it seems to have started working as expected, thank you.

I would have expected that setting to be On by default, but there is probably a good reason why the default is Off. I did see that setting when I was trying to get it to work, but the description gave me the idea that it needed to be enabled only if one was to add some custom commands that needed polling. In hindsight, I should have tried turning it on.

[luc-github]

This setting is not necessary if your firmware do autoreporting - autoreporting is far better than polling because no need to ask - just listen and so save bandwidth - that is why it is off by default.

Please close issue if all is ok and have fun - feel free to read https://esp3d.io documentation also ^_^

You are absolutely right. I did not know about the autoreporting, I will enable it in the Marlin firmware and disable polling.
Thank you for your help and the great software.
