Azure IoT Handle Example for Speaker play_cloud command?


  • Anyone know what to put here for the Payload? I want to play a sound with the play_cloud command.

  • I added it to my model so you get a UI field in Azure now for pasting in the cloud wav file URL:

    The command gets to the device but it can't parse it for some reason, get a Data Format Invalid error.

    Traceback (most recent call last):
  File "libs/m5mqtt.py", line 101, in _msg_deal_task
  File "libs/m5mqtt.py", line 88, in update

  • I also tested this with a local file but get a different error:

    OSError [Errno 2] ENOENT
    0

  • In case anyone else has the same issue...the handler works if you hard-code the path to the Wav file

    but cloud path doesn't work with the same trick, it still gives the Data format is not valid error.
