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

  • M

    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.

  • 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?
