Vigilant Engine

Vigilant Engine is the framework on which all ESP-based nodes of the Starstreak project are built.
It provides the fundamental building blocks for connected, remotely maintainable devices, including reliable OTA updates, flexible network modes, and peripheral support.

Core Features

• OTA (Over-The-Air updates)

  • Firmware updates via HTTP/Web UI
  • Designed for safe, recoverable updates on ESP targets

• Network Modes

  • AP – Device creates its own access point
  • STA – Device connects to an existing Wi-Fi network
  • APSTA – Dual mode (access point + station)

• Webserver

  • Serves configuration & status pages
  • Handles OTA firmware upload
  • Endpoint structure designed to be extendable per project

• Debugging

  • Wireless debugging over the network (e.g. TCP terminal)
  • Centralized logging API for modules
  • Optional verbose / debug builds

Peripherals

Vigilant Engine includes drivers / integration for:

• WS2812B – Addressable RGB LEDs (status indication, effects)
• TCAN4550-Q1 – SPI CAN controller
• TCAN332 – CAN transceiver

These peripherals are wrapped in a common abstraction layer so they can be reused across all Starstreak nodes.

Partition setup and the Flasher

Vigilant engine is made from two main partitions, the factory partition, and the ota_0 partition.
