🧬 UID Traceability & OTA Firmware Architecture

Extreme-Spartan Cognitive Industries Pvt. Ltd.


🔍 Overview

This system ensures every deployed ESCAPE-chip is uniquely identifiable, remotely updatable, and audit-traceable across its lifecycle. It combines:

  • UID Manifesting
  • OTA Firmware Delivery
  • Edge AI Sync
  • Compliance Logging

🧠 UID Manifest Structure

Field Format Description
UID Code HEX + Timestamp Globally unique per chip
Sensor Map JSON LiDAR, GPS, IR, Thermal, Optical
Deployment Tier Enum [Pilot, PPP, Summit, Field]
OTA Status Boolean Firmware sync enabled
Compliance Tags Array ISO, PPP, NSDC, UID-Ready
QR/NFC Overlay Embedded UID Access For field scan & audit

📡 OTA Firmware Architecture

Layer Framework / Protocol Function
RTOS Base ESP-IDF / FreeRTOS Task scheduling
OTA Manager HTTP / MQTT Firmware push/pull
UID Sync Layer JSON + QR/NFC UID traceability
Cloud Bridge AWS IoT / Azure IoT Remote diagnostics
Security Layer TLS + JWT Auth & encryption
Rollback Logic Dual Partitioning Safe fallback if update fails
