I am trying to connect my WiFi enabled MCU to Alexa. It should only take 2 commands for the begining. I created a custom skill before, by connecting my skill to Heroku but it is not expandable. I need to create a Smart Home Skill that communicates with Alexa. I inspected all the pages that Amazon provided but there is no section like "Your end device should return like this ... to ...(UDP/TCP etc.)" or "Your end device will get this info .... from ... (UDP/TCP etc.)".
What my device should return to which request given by Alexa when you say "discover" to it?
I found some examples for MCU code. When I inspect them I saw them they replicated WeMo or Philips devices that allows only "Turn On" and "Turn Off" commands.
The reason why I am using Alexa is to avoid using microphone and voice recognition unit in hardware design. So local connection is acceptable.
Today I started over from the begining. Created new lambda function and new smart home skill. Now I stuck here. What should I do for MCU to make them recognise each other?
I would be so glad if you provide this information to me or tell me where to find this information.
