Lights ESP32

ESP32-based BLE-enabled light controller for synchronized wireless lighting systems. Acts as the central BLE hub for controlling multiple ESP-NOW synchronized lights via iOS app.

Description

This project implements the ESP32 firmware for a wireless lighting control system. The ESP32 serves as the BLE bridge between the iOS control app and the ESP-NOW mesh network of synchronized lights.

Features

• BLE Server - Provides BLE connectivity for iOS/macOS control apps
• ESP-NOW Integration - Communicates with mesh network of lights
• Multi-Device Sync - Coordinates with ESP8266-based light nodes
• Animation Modes - Supports various lighting animations and patterns
• Power Control - Adjustable brightness and power settings
• Low Latency - Sub-millisecond synchronization with mesh
