notes over a smart foot brace based on ZNX-01 and IMU, communicating with a Node-RED UI (vers 01. and 0.2) and later using BLE and P5js (vers 0.3)

Version 0.3 Bluetooth Low Energy Version

Video Demo

The sole sends data via BLE. To visualize this project we used p5js, and its implementation of the BLE library Here is the code

La suola trasmette tutti i dati attraverso bluetooth. Per visualizzare questo progetto abbiamo usato p5js, e la sua implementazione della libreria BLE Qui il codice

Version 0.2 ESP32 + ZNX + IMU! + UI in Node-RED

Video Demo (sorry this is note yet subtitled)

Old info about version #1 (Italian only)

Version 0.1 ESP32 + ZNX + UI in Node-RED

Come si usa il prototipo 1?

Per poter visualizzare sul PC i dati della suola smart occorre:

Lato Arduino (Opzionale)

Lato Node-RED (obbligatorio)

Una volta fatte queste operazione e importata la prima versione della UI, dovrete correttamente identificare la COM che il vostro PC ha assegnato all'ESP32. Selezionandola dal dropdown del nodo dovreste essere in grado di vedere i dati vairare in tempo reale nella dashaboard.

Al momendo la comunicazione é seriale, i dati vengono inviati in JSON, in questo protocollo:

{
    "vers" : 1,
    "gfrValue8" : num,
    "gfrValue7" : num,
    "gfrValue6" : num,
    "gfrValue5" : num,
    "gfrValue4" : num,
    "gfrValue3" : num,
    "gfrValue2" : num,
    "gfrValue1" : num
}
