Edit: this is the code for sending data in one direction:

CubeCell:

Heltec ESP32:

Node.js:

This is the code to send from the websockets server to the Heltec ESP32 to the Heltec CubeCell and blink based on the result of a particular string:

(see : https://gist.github.com/bshambaugh/4481addef68862bc5891d187d4391258 for websockets going the other way)
