Stop! Before you proceed:

This Get Started Guide is an older version and it is neither maintained nor supported anymore.

It is kept here for reference only and should not be used for any new development.

If you’re looking for a Get Started guide to the Espressif ESP32 there are two alternatives available:

1. Azure IoT SDK for C which uses a bare metal approach (no RTOS) and support for Arduino IDE.
2. Azure IoT middleware for FreeRTOS which uses ESP-IDF.

2022-04-08 Update:

For reference and testing, the source code of az_iot folder has been updated using the az_iot folder of the official https://github.com/Azure/azure-iot-sdk-c using commit: cb8ef0535ebd06f81231be4c40b372ef17cd995e.

Using this source code, the project can be build for esp-idf v4.4 and Arduino Core 2.x

ESP32_AzureIoT - Azure IoT Hub library for esp32 devices in Arduino

This library is a port of the Microsoft Azure IoT device SDK for C to Arduino for esp32 devices. It allows you to use several Arduino compatible ESP32 boards with Azure IoT Hub.

Currently supported hardware

• ESP32 based boards with esp32/arduino
  • M5Stack

It should also work for other esp32 boards.

Prerequisites

You should have the following ready before beginning with any board:

• Setup your IoT hub
• Provision your device and get its credentials
• Arduino IDE 1.8.5

SimpleMQTT and GetStarted Instructions

1. Install esp32 board support into your Arduino IDE.

   • Start Arduino and open Preferences window.
   • Enter esp32 package URL https://dl.espressif.com/dl/package_esp32_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
   • Open Boards Manager from Tools > Board menu and install esp32 platform.
   • Select your esp32 board from Tools > Board menu after installation

2. Open the SimpleMQTT or GetStartedexample from the Arduino IDE File->Examples->ESP32 Azure IoT Arduino.

3. Update Wifi SSID/Password and IoT Hub Connection string in ino file

   • Ensure you are using a wifi network that does not require additional manual steps after connection, such as opening a web browser.

4. Access the Get Started tutorial to learn more about how to get started with physical devices.
