Unable to turn off Uplink reconnect and uplink IP

[ggee]

I am unable to turn off the LCC WiFi Uplink 'Uplink reconnect'. When I turn it off and click save, the slider turns back on and strangely the 'Connect to Network' button appears. I also constantly see the following message in the serial monitor.

[Uplink] Reconnecting to 192.168.10.170:12021. connect: Software caused connection abort

There seems to be no way to forget the uplink settings.

I can confirm that's happening here as well.

Uplink reconnect goes back to On position

I had to do a Factory Reset to clear the uplink IP. Not sure if it was related, but when the problem was occurring, it was difficult to keep a stable DCC++ Ethernet connection from JMRI. The response was very slow and sometimes seem to take 30 seconds for the command to be executed to just stop. The power status would occasionally report as Unknown.

Do you need to add the uplink manual host value though?

For me that field is empty, as I have the mode setup to Auto, Manual, and mDNS finds JMRI no problem via the LCC network.

[ggee]

Yes, the field is empty for me as well. I'm not sure what I clicked to get the CS to try and connect to JRMI constantly.

[atanisoft]

@ggee the CS tracks the last known address that it successfully connected to and will by default try and reconnect to it. If that connection fails though it doesn't fallback to trying to find a new address. I'll add an option to clear the last address.

@ggee can you test the update in https://github.com/atanisoft/ESP32CommandStation/pull/71? If you used git clone to setup your local copy of the CS code you can run git checkout uplink and it should pull in the changes from that PR and you can then run idf.py build flash monitor

I'm running into a problem. I entered an IP and port in the LCC Uplink manual host/port, then I saved. Then I deleted the two values and pressed save. This caused the node to crash.

mDNS Service Name: blank LCC Uplink manual host: blank LCC Uplink manual port: blank Uplink reconnect: On

Rebooting...

[atanisoft]

I'll take a look into it. It should have persisted the config but may not have flushed to disk when it crashed.

[atanisoft]

I've merged PR #71 to master but not closed this as I'm going to dig into what went wrong with the above exception on my desk before closing this. I'd also like to offload the uplink creation if I can so it doesn't block the main thread.

[atanisoft]

@ggee I've put your crash dump in https://github.com/atanisoft/HttpServer/issues/7 for tracking and applied a workaround for blank parameters. This fix will come in via https://github.com/atanisoft/ESP32CommandStation/pull/90
