Code Examples

Ready-to-use MQTT-based examples for different platforms and environments.

  • STM32Cube MQTT Client - a FreeRTOS-based implementation for STM32 microcontrollers using generic AT command-based cellular modems like SIM7000

  • Python 3 - suitable for use on Single Board Computers (SBCs) like Raspberry Pi and some Industrial IoT gateways

  • MicroPython - a fun and easy way of creating the device firmware

  • Arduino / PlatformIO - a pre-configured project that supports over 15 connectivity-enabled boards, including the Espressif ESP32, Raspberry Pi Pico W, Nano 33 IoT, Nano RP2040 Connect, UNO R4 WiFi, Seeed Wio Terminal, etc.

  • Plain C with the Mosquitto library - tailored for advanced use cases needing high performance, compact size, or system-level integration

  • Lua - ready for deployment on OpenWrt-based routers and SBCs like Onion Omega2

  • HTML5 / JavaScript - thanks to the WebSocket technology, this example can be used directly from the browser‍

  • ESP-IDF Cellular - for Espressif ESP32 devices with a cellular modem
