@ajb2k3 thanks for explaining, simply adding WLAN STA connect to SSID results in a Internal wifi error.. setting the wifi via the webburner isn't helping either. example as cheatsheet would be helpfull.

hi all,

this is all very new to me so please bear with me.
I want to use the m5 stack on my sailboat as a display for my rudder pos and depth. Both values are being published over mqtt via node red.

When i run this uiflow everything works fine and the mqtt values are being displayed on the device. But when i press download to the device i get an error:

traceback (most recent call last: file "main.py" line 69, in <module>
file "main.py"line 52, setup
file "umqtt/simple.py", line 68, in connect
0SError: [Errno 118] EH0STUNREACH.

what am i doing wrong ? :)
Many thanks for any advice.
