Wire & Flash

Wire ESP32 + MFRC522 (3.3V, SPI), install the Arduino library, flash our firmware. Serial monitor confirms connection at 115200 baud.

// 5-wire SPI connection
SDA → GPIO 5
SCK → GPIO 18
MOSI → GPIO 23
MISO → GPIO 19
RST → GPIO 22
⚠ 3.3V only — not 5V!

Register on Portal

Create a free account at uid.auralock.in. Go to Devices → Register → note your Device UID. Use the USB Setup Tool (Chrome/Edge) to write WiFi + credentials directly to the ESP32 flash.

// Your device UID looks like:
AURA-A1-R-001
// Token format:
AURA-SEC-XXXXXXXXXXXXXXXX

Firmware v1.2.2

Arduino Firmware

The AURALOCK A1 firmware is built on the ESP32 Arduino framework with MFRC522 SPI driver. Configuration is stored in NVS — no hardcoding required when using the USB Setup Tool.

  • ✓ Non-volatile config storage (NVS/Preferences)
  • ✓ WiFi auto-reconnect with 25s timeout
  • ✓ Heartbeat every 60 seconds
  • ✓ 800ms debounce — no duplicate scans
  • ✓ 10 MHz SPI for reliable reads
  • ✓ LED on GPIO 2 blinks on every scan
