🔁 OTA Failure Recovery Logic

Extreme-Spartan Cognitive Industries Pvt. Ltd.

🔍 Failure Scenarios

  • Interrupted OTA transmission
  • Firmware corruption
  • UID mismatch
  • Sensor desync post-update

🧠 Recovery Architecture

Component Functionality
Dual Partitioning Safe rollback to previous firmware
UID Sync Validator Ensures UID integrity post-update
Sensor Recalibrator Reinitializes sensor map
OTA Retry Manager Queues failed updates
Audit Logger Records failure + recovery trace
