WiFi Module Not Recognized - Duet 3 6HC Mainboard

big_plotter_man

Hi all,

I recently purchased a Duet 3 6HC Mainboard with a WiFi module. During setup, I noticed that the WiFi module didn't light up when I plugged the mainboard's USB cable.

Also, whenever I used the M552 command, it would respond with Ethernet is disabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0.

I updated the mainboard's firmware to 3.4.6 and was able to successfully perform a firmware upload to the WiFi module with M997 S1 but checking the board's network status using M552 always mentions ethernet instead of WiFi and attempting to connect to a network results in the following error:

Error: M587: Failed to add SSID to remembered list: WiFi module is disabled

I've tried the above with another WiFi module which results in identical results and the voltage drop between PWR and GND on the pins for the ESP are the correct ~3.3v.

@big_plotter_man Are you using I1 in the M552 commands?

See https://docs.duet3d.com/en/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6HC_Hardware_Overview#wifi-v102

Send M552 I1 S0 to take the WiFi module out of its disabled state and into idle.
Use M587 to add the SSID and password of your wifi network. Note, it does not need to be the same network that the ethernet is connected to. The WiFi interface will get its own IP address via DHCP, or you can specify what IP address to use in the M587 command.
Send M552 I1 S1 to enable the WiFi interface in client mode and connect to an access point that you specified using M587. Send M552 I1 or M122 to see the configured IP address.
You can add this to config.g if you want WiFi to be enabled on boot.

Need a lot more information here. For starters, the full M552 and M587 commands you're using and a photo of how you have it installed would be helpful.

Thanks! That appears to have fixed my issue and now my MB6HC can now consistently connect to the internet.
