ESP32 FastLED BLE (Bluetooth Low Energy)

Web BLE control app: https://jasoncoon.github.io/esp32-fastled-ble/

** Currently only supported in Chrome on MacOS, Windows, and Linux

Work in progress BLE port of https://github.com/jasoncoon/esp32-fastled-webserver

Control addressable LEDs with an ESP32 via a web browser over BLE.

Features

Current Status:

• DemoReel100 patterns
• FastLED ESP32 multi-core parallel output support
• Setting storage in EEPROM
• Ability to adjust these settings via BLE:
  • power on/off
  • brightness
  • pattern
  • autoplay on/off
  • autoplay duration
  • speed
  • palette
  • auto palette cycling
  • palette duration
  • solid color
  • twinkle speed/density
  • fire cooling/sparking

Requirements

Hardware

ESP32 Development Board

• Adafruit HUZZAH32 – ESP32 Feather Board
• WEMOS LOLIN D32
• NodeMCU-32S Board
• ESP32-DevKitC Board
• An ESP32 development board of your choice

Addressable LED strip
