-# MQTT Implementation Notes
-
-* WiFi connection runs in a separate task with auto-reconnect functionality
-* Network stack operates in a dedicated packet processing task
-* MQTT uses TCP socket connection (MqttClient wraps this socket)
-* ClientConfig specifies: MQTT version, QoS levels, client ID
-* Standard flow: connect_to_broker() → send_message() or subscribe()
-
-## Implementation:
-1. Perform DNS lookup for broker hostname
-2. Establish TCP socket connection
-3. Create MqttClient with configuration
-4. Implement connect, publish, and subscribe logic
