m5Dail MQTT and Wifi Help



  • Please i need some help to set up a simple MQTT to send and receive messages
    i bought the M5Dail over 3 months ago and i still cant use it, i keep getting all kind of errors, i updated to the latest firmware and its still not working
    0_1708954894539_035d4811-b035-40af-9721-fe7ed27e15ef-image.png

    then i get these errors, including on the screen
    0_1708954943111_7060e1fc-a12d-4b69-86ef-51551794e3e1-image.png

    Edit: Even if i try to just setup a simple WIFI client, i get this error
    Traceback (most recent call last):
    File "<stdin>", line 22, in <module>
    File "<stdin>", line 15, in setup
    OSError: Wifi Internal Error

    Can anyone please post your flow of a working MQTT?
    thank you



  • I'm using external Hive MQTT and it didn't worked with build in blocks for mqtt on my M5Dial so had to use "execute code" way and it was fine

    add wifi config to your code too



  • I posted an example in UIFlow2’s project zone for the atom. I found the issue is with the placement of the MQTT unit block

    The error says the host is unreachable, are you sure you have the correct address?



  • Thank you for the quick replies, i think i managed to make it work, it seemed to be an issue with WIFI
    now i can publish messages everytime i rotart the dial, but the new issue i'm having is receiving messages (or in other words Subscribing)
    below is a sample bock code, i would receive one message then it stops receiving.
    do you know the block "MQTT Apply For Messages" what is it used for? if i add it i would receive one message, i tried adding in the subscribe blocky but then i cant publish, any idea what i'm doing wrong?

    are you publishing and subscribing to same topic or two different so something else is acting for topic you subscribing?



  • Hi guys

    please find my M5Dial MQTT (subscribe and publish) example called M5Dial_WiFi_MQTT_UIFlow2.0.1 in the UIFlow2 Play Zone.

    BTW: MQTT apply for messaging (e.g. mqtt_client.wait_msg() block is a blocking call, e.g. it waits until a message is received. If you only want to check for new messages (non blocking) you'll need to use an Execute mpy code block with mqtt_client.check_msg() in it.

    Thanks
    Felix
