WiFi module auto reconnect

Drammy

I read lots of problems with WiFi network dropouts and being unable to reconnect.

I can recreate this at will..

Power on wireless router
Power on Duet Wifi
Wait for duet to connect to WiFi
Restart router
Duet now shows network error and idle network in Paneldue console
Wireless router WiFi signal becomes avaialable
Duet WiFi will not auto reconnect and requires M552 S-1 followed by M552 S1 in order to reconnect.

Why can it not simply try again every X seconds like most wireless devices do?

Currently it does two auto reconnect attempts, but it gives up after that. I'll review this in the 2.02 release.

Thanks David, that would be great.

Perhaps a logarithmic increase in pause duration between retries.
This has become somewhat standard in web development nowadays and might prove a good compromise for the duet WiFi server..

@dc42 can you also plan the "stop" button getting a priority if initiated from the paneldue for 2.02? I know you have described how this works, but the closest thing on the printer a lot of time when something goes wrong is the stop button on the screen and when it fails to stop anything it almost defeats the purpose. on some printers I have the power button is accessible but on the duplicator 6 its in the back so I end up scrambling trying to get it to stop.

@bpislife I've noticed this too and yes it would be a good improvement IMO.

I think you might be better creating your own post though as its going off-topic somewhat..

@dc42 Hi there,

I was just wondering if you've included this in the 2.02 release as I can't see it in the WhatsNew notes.

I know this isn't related to auto reconnecting but I've found that the wifi connectivity when using DWC is much more prone to disconnects since upgrading to v2.0 and above. At best I can connect for about a minute before being disconnected.
To be honest I've not investigated but it looks to me like the web server is taking too long to return API calls and DWC just disconnects.
Is there anything that can be done about this?

It's still on the work list, but right now I am busy getting firmware ready for the TCT show.

Auto reconnect is implemented in firmware 2.02RC3.
