m5tough UIFlow2.0 Alpha 24. mqtt. first-timer needs some guidance

[Maasi]

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.

You need a Wifi network for the data to be shared.When you test, devices are already connected to a network but when you download, you need to set a network for devices to use.

@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.

[ajb2k3]

You need two devices, one set as AP and one as STA for it to work.
What error are you getting when set to STA?
