This is for personal knowledge. I’m using a Nodemcu with 8266 WiFi module. I have most of the stuff done, WiFi connection, web server and [login to view URL] file to receive the data and display that data. What I need help with is that I added a sensor that uses serial communication to send commands and responds serial data exp: sensor response is: 11 03 08 00 64 00 3E 00 0D 00 55 9C. I need this response to an array then send to the server, then the server sends that data to the html file and converted back to an array to display each byte value! I would like to use xml and Json format. Also detailed explanation how it was done! I want to learn, not just the solution! For this project, you’ll need to know Nodemcu, SPIFF file, Arduino IDE, XMLHttpRequest and JavaScript, XML, and Json.
