Problem with Yaml demo file

[Bigh]

I am trying to install the A16 rev 1.6 for ESP Home Assistant.
The A16 connects and is recognized
When I try to load the sample YAML file I get an error message
What should I change so that it works properly and I can see all the characteristics of the card and I can program it directly from the software
