@jerryneedell Great job on this new library! I set up two radio featherwings to try it out and everything was very smooth sailing to get them running under this new module.

This is similar to the exist simple transmit example but is modified to send a dictionary payload using msgpack

Where do the io and msgpack modules come from for this example?

I should add that I am trying to run this on Raspberry Pi and pip is not finding them. Are they available for "blinka"
I see that they are part of the CP core. I'm just wondering if this example can also run on a Pi?

Nevermind -- pip install msgpack adafruit-io got them.

They are from core modules.

from io import BytesIO exists as a built-in module in CPython as well and I believe it works the same, but I have not tested it.

msgpack is in the circuitpython core. But in CPython it is not a built-in module. It's installed from pip https://pypi.org/project/msgpack/. However I am not 100% sure if the API is the exact same as CircuitPython.

on the Pi, If I try to run this on two systems, I get this error when I start the second:

I was getting an error that no module io was found until I installed adafruit-io

The problem may be that the startup message is not constructed with msgpack - Is that causing the error.

Yes -- I think taht is its -- I just commented out the startup message and it works fine.

Looks great -- Nice example!
