Welcome to the official documentation for the Intellidwell Quiz Buzzer System. This platform provides an ultra-low latency, commercial-grade trivia game show experience designed for classrooms, trivia nights, pub quizzes, company events, and party games.

Why ESP-NOW Star RF Topology?

Connecting multiple individual ESP32 remotes directly to a local Wi-Fi router or phone hotspot introduces several bottlenecks:

• Network Client Caps: Mobile hotspots and basic access points often limit active connections (typically 8–10 clients max).
• TCP/IP Latency & Jitter: Standard Wi-Fi association and packet queuing add 50–200ms of unpredictable latency, making fair tie-breaking difficult.
• Battery Consumption: Maintaining active Wi-Fi associations draws ~80–120mA continuously, draining batteries quickly.

The Superior Solution: ESP-NOW Star Network

Key Advantages:

• Sub-5 Millisecond Latency: Packets transmit virtually instantly with zero handshake or association overhead.
• Deep Sleep Power Saving: Remotes sleep at ~44 µA and wake up in microseconds via hardware GPIO interrupts upon pressing any button.
• Bidirectional Acknowledgment: Hardware MAC ACKs and broadcast feedback packets provide instant LED confirmation (Green for winner/ACK, Red for locked out).
