This guide explains the design, architecture, and step‑by‑step usage of an AT command parsing library for bare‑metal and OS‑based systems, covering job queue management, core APIs, example code, and integration with modem, Wi‑Fi, and Bluetooth modules.
This guide details a lightweight AT command parsing module supporting both bare‑metal and OS versions, explains its architecture, core data structures, key APIs, and provides step‑by‑step usage examples—including GPIO testing, signal‑quality queries, and TCP data transmission—for modems, Wi‑Fi and Bluetooth communication.
This article introduces an AT‑command communication parsing module that supports both bare‑metal (at_chat) and OS‑based versions, explains its software architecture, core data structures, key interfaces, and provides step‑by‑step usage examples with complete C code snippets for Wi‑Fi, Bluetooth, and modem integration.
This tutorial walks you through downloading the source, understanding HC‑08 specifications, wiring the module to an STM32F103C8T6 board, using AT commands to configure roles, power modes, and connections, and implementing UART‑based send/receive code to enable bidirectional communication with a mobile app.
This article explains the purpose and syntax of AT command sets used in IoT, details common NB‑IoT commands with examples, and introduces popular serial debugging tools such as IoT Studio and QCOM for effective module testing and network management.
