LibGSM Generate MQTT Publish and Subscribe Code - GSM Library

Описание: This video provides a step-by-step guide on starting an MQTT SIMCom LTE project using the LibGSM Code Generator. It covers selecting the necessary modules, generating code, configuring GPIO and UART connections, updating project files, subscribing to topics, and publishing messages to this same topic. Received messages will be output on a serial channel. Additionally, by watching until the end, you’ll learn how to integrate heartbeat LED functionality and modify flashing routines based on specific MQTT messages that are received.
