- The front end is written in React because it is very easy to bootstrap a ReactJS project using
npx create-react-appcommand and start developing UI! - The front end uses a library called
react-speech-kitthat helps to do the voice-to-text conversion. I followed this bloghttps://www.commoninja.com/blog/how-to-convert-speech-to-text-in-react-with-the-react-speech-kit. Here is another nice blog on this -https://blog.openreplay.com/make-your-app-speak-with-react-speech-kit/ - When a command is received at the front end, it is sent to the backend for processing. The backend is a REST API written in golang. The backend receives the command over HTTP and sends the command to the ESP8266 device via TCP. Go code is acting as a http listener for the React App and a TCP client to the ESP8266 device, a gateway to the device to send command from the ReactApp.
- Finally there is a tcp listener written in micropython which is running in the ESP8266 device. The tcp listener receives the command and executes it on the hardware.
- Don't use cheap charing cable to connect, use proper data cable. I had no idea there is a difference. Apparently there is a difference (https://www.dignited.com/50330/usb-data-cable-vs-usb-charging-cable/) which I did not know! This blog helped (esp8266/Arduino#3551)
- Dealing with bare metal is hard, lots of trial and error , guesswork, reading and searching solution which can be a bit challenging , so be patient. Happy IOTing....
