Solved Duet cannot connect to WiFi after the upgrade to 3.4.5 firmware

[skayred]

Hello,

I have recently installed the 3.4.5 firmware from the 3.0 version, DWC upgrade hanged, so I have had to install it via the SD card and USB interfacing.

Now, I face the really weird issue - when I turn on the board via the 12V or USB, I can see that it cannot initialize the WiFi connection. If I use the M552 command to stop the interface and start it again, it properly connects to the hotspot. If I reconnect the USB, WiFi connection works, but if I unplug USB and run 12v - no connection happens. If I plug in USB again, connection doesn't happen until the M552 cycle.

This is the output I see from the terminal emulator:

RepRapFirmware for Duet 2 WiFi/Ethernet version 3.4.5
Executing config.g... HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Warning: Heater 1 predicted maximum temperature at full power is 549°C

ok
WiFi module is connected to access point skayred-aux-tw, IP address 192.168.0.201

Any ideas what could be a reason for that behaviour?

@skayred occasionally, upgrading the wifi firmware fails. Try sending M997 S1 from USB or PanelDue.

@dc42 just tried, terminal shows the percentage and indicates that the installation was successful. But when I try to power it from 12v, PanelDue stays in the Connecting state.

NB: as I was updating from the version 3.0, I had to put the binaries into the /sys, could it try to install the WiFi driver from the /firmware instead (I might have some older version within this directory)

[skayred]

Tried to put the firmware into the /firmware folder, update seems to go well, but PanelDue still stays in the Connecting state. But at least DWC works, so WiFi appears to be okay.

@skayred said in Duet cannot connect to WiFi after the upgrade to 3.4.5 firmware:

PanelDue still stays in the Connecting state

That may mean that you don't have the M575 command to enable PanelDue support in config.g.

@dc42 thank you, that was exactly the reason!
