SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill centralizes operational knowledge and diagnostics for ESP32 devices to quickly identify firmware, hardware, and communication failures from serial logs, MQTT traffic, and server artifacts, reducing mean time to resolution.

Core Features & Use Cases

  • Boot and SafeMode Analysis: Step-by-step boot-sequence checkpoints, safe-mode triggers, and LED/serial patterns to pinpoint initialization failures.
  • Error-Code Reference & Actions: Full 1000–4999 error-code mappings with suggested hardware checks, configuration fixes, and server cross-checks.
  • Communication & Circuit Breaker Diagnostics: MQTT and WiFi circuit-breaker behaviors, topic schemas, QoS expectations, and recovery workflows for offline or degraded devices.
  • Cross-Layer Troubleshooting: Practical workflows combining serial logs, Docker service status, database queries, and MQTT observation to resolve sensor, actuator, and watchdog issues.
  • Use Case: When an ESP32 repeatedly reboots and stops publishing sensor data, use this Skill to analyze serial output, evaluate boot-loop counters, inspect circuit-breaker events, and correlate server-side heartbeat logs to determine root cause and remediation steps.

Quick Start

Open the primary ESP32 serial log and inspect boot, error code, and circuit-breaker patterns to determine whether the device is in safe mode, experiencing hardware faults, or suffering connectivity problems.

Frequently Asked Questions about esp32-debug

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug an ESP32 that keeps rebooting and stops publishing MQTT data?

To debug an ESP32 that keeps rebooting, analyze the serial output to evaluate boot-loop counters, inspect circuit-breaker events, and correlate server-side heartbeat logs to determine the root cause and remediation steps.

What do ESP32 error codes 1000 to 4999 mean during firmware diagnostics?

ESP32 error codes from 1000 to 4999 indicate specific hardware faults, configuration issues, or server discrepancies, and interpreting these codes involves mapping them to suggested hardware checks and server cross-checks for resolution.

How do I diagnose MQTT and WiFi circuit breaker events on an ESP32?

Diagnosing MQTT and WiFi circuit breaker events involves analyzing circuit breaker behaviors, validating topic schemas and QoS expectations, and executing recovery workflows to restore offline or degraded ESP32 devices.

How do I trace ESP32 boot sequence failures and safe-mode triggers?

Tracing ESP32 boot sequence failures requires checking step-by-step boot-sequence checkpoints, verifying safe-mode triggers, and reading LED and serial patterns to pinpoint exact initialization failures.

Can I cross-reference ESP32 serial logs with Docker services and database queries?

Yes, you can cross-reference ESP32 serial logs with Docker service status and database queries through practical cross-layer troubleshooting workflows to resolve sensor, actuator, and watchdog issues.

Do I need external scripts to analyze ESP32 serial logs and server telemetry?

No, you do not need external scripts to analyze ESP32 serial logs and server telemetry, because the diagnostics operate using grep-based analysis workflows and reference lookups without requiring external script dependencies.
