MQTT Embedded Integration

Overview

Use this skill for MCU MQTT clients by separating network link, TCP/TLS transport, MQTT session state, topic design, QoS, keepalive, and reconnect policy. MQTT success requires more than one successful publish.

When To Use

Use this skill when:

• The user wants MQTT on an MCU or embedded device.
• The task involves MQTT connect, publish, subscribe, keepalive, QoS, Last Will, retained messages, broker auth, TLS, reconnect, or offline buffering.
• The issue is connection drops, no messages, duplicate messages, memory growth, TLS failure, or reconnect storms.

Do not use this skill when basic IP connectivity is not working. Use lwip-integration or platform network debugging first.
