Panel Due Hanging Up after loss of Wifi

Hornetrider

Hi there

some time ago I have expirienced the behaviour of freezing communication between PanelDue and DuetWifi. And it allways happens when the Wifi Module reports a lost of connection.
After running all latests updates, both on PanelDue and DuetWifi and resetting the Wlan Hotspot (finding a better channel) this issue was gone for a while.
But now last week it started again.
I have rebootet my Hotspot, and set the Wifi channels to less used channels. The connection has become stable again, at least for now.

In my opinion the freeze of the comm is related to the procedure on how the DuetWifi handles the Wifi connection initialisation and time out.
I have also noticed, that right after restart of the DuetWifi and before the Wifi conn is established the communication between the PanelDue ant the DuetWifi is extremly delayed.
For example:

Switch on DuetWifi
run Home all (during this period the Wifi Conn is not established as the machine has something different to do...)
after Home all and without promt of Wifi Conn-> try to activate a Makro or reading out files via PanelDue...extreme delay in 10+ sec
right after the Wifi has established a stable Connection everything works fine and in usual speed
One more thing. The "Wifi lost conn" occurs shortly after the first connection build up (prompt by Duet) or even during a print.
Only the STOP button on the Paneldue keeps working!

More to come...

Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.0 (2020-01-03b3)

Update your firmware to 3.1.1 and ensure your PanelDue is at 1.24.

Upload this zip file as is to the /sys folder via DWC: https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

https://duet3d.dozuki.com/Wiki/PanelDue_Firmware_update

Ensure you have M575 P1 S1 B57600 in your config.g for the PanelDue to work properly in 3.1.1

Hornetrider

@Phaedrux
Thx, I'll give it a try.

BTW. FW1.24 is on the Due

Does FW3.1.1 implement a new FW for WiFi too?

dc42

RRF 3.1.1 uses WiFi firmware 1.23.

Hornetrider

@dc42
So no change in wifi connection handling?
