2026-08-02
Review fixes: Serial ERROR→ESP_LOGE, heartbeat→ESP_LOGD
- Replace remaining Serial.println("ERROR:...") with ESP_LOGE in client.cpp
- Add Serial.println("ERROR") for protocol response where needed
- Downgrade heartbeat from ESP_LOGI to ESP_LOGD (not needed in production)
Replace Serial.* logging with ESP_LOG* macros (issue #8)
- Convert all Serial.println/printf debug logging to ESP_LOGE/W/I/D - Add TAG-based log identification (server/client) - Lower CORE_DEBUG_LEVEL from 5 to 3 for production - Keep Serial.printf for USB serial protocol commands (KEY?, VERSION?, etc.)
