ESP8266 Community Forum

The display of the following software has been confirmed with device explorer for connecting Azure Iot.
I want to replace this software with esp8266.
Please tell me how.

You should be able to just replace the MQTT library with the ESP8266 version. Rest is all very generic

Thank you very much.

excuse me but,
In order to do the following method, the same as #include "Esp32MQTTClient.h"
If you have the ESP8266 header file
Please tell me how to get it.
Please tell me the library required to use the header.


Reason: To connect to Microsoft Azure,
if (!Esp32MQTTClient_Init((const uint8_t*)connectionString))
{
Find the part that corresponds to
This is because you need to create a program.
I haven't found the MQTT communication header for the ESP8266 that can do this, so
MQTT communication
I gave up half.

There are multiple Arduino library packages so you just install it using your package manager. The libraries come with multiple examples so you will be able to easily see what to replace.

The most common one for ESP8266 seems to be the generic PubSubClient package, which works pretty well. This is the documentation: https://pubsubclient.knolleary.net/api
