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.
