No WiFi reconnection logic in main loop
High Severity
The loop() only handles MQTT reconnection but never checks or recovers WiFi connectivity. setupWiFi() is called once in setup() and WiFi.setAutoReconnect(true) is never called. ESP32 does not auto-reconnect WiFi by default, so if WiFi drops, the device permanently loses network connectivity. The MQTT reconnect branch will repeatedly call connectMQTT() — which blocks for up to 15 seconds per attempt via PubSubClient's socket timeout — making the device unresponsive with no path to recovery.

Note
Medium Risk
Introduces new WiFi/MQTT connection, periodic publishing, and remote command handling in the main firmware loop; connectivity/loop timing issues could affect device stability but changes are contained to startup/telemetry code.
Overview
Bootstraps the ESP32 firmware in
src/main.cppwith WiFi setup and an MQTT client: connects/subscribes on startup, auto-reconnects inloop(), publishes periodic placeholder sensor payloads, and emits a JSON status message (uptime/heap/RSSI). It also adds basic command handling overmicroclaw/commands(requeststatusandrestart).Improves project onboarding by expanding
README.mdwith PlatformIO install/flash instructions (IDE/CLI/manual), troubleshooting, and project structure, addslib/README.mddescribing how to add custom sensor drivers, and broadens.gitignoreto exclude build artifacts, IDE/OS files, logs, and secret env/header files.Written by Cursor Bugbot for commit d1ac3bc.
