You can you this code. You only need to change WIFI SSID and Password Certainly! Here's an example README file for your code:
This is an example project that demonstrates how to establish a Wi-Fi connection on an ESP32 device and connect to an MQTT broker using the ESP-IDF framework. The code sets up a Wi-Fi connection, connects to an MQTT broker, and demonstrates basic MQTT operations such as subscribing to topics and publishing messages.
Before running this code, ensure that you have the following:
- An ESP32 development board
- ESP-IDF framework installed on your development machine
- Wi-Fi credentials (SSID and password)
- MQTT broker URI and optional authentication details
Please go to my main.txt file
The ESP32 device will automatically attempt to connect to the configured Wi-Fi network on startup. Once connected, it will connect to the MQTT broker using the provided URI. The device subscribes to the topic /topic/test1 and /topic/test2 and publishes messages to those topics.
You can modify the topics and messages by editing the code. Additionally, you can customize the behavior of the MQTT client by adjusting the configuration parameters in the code.
-
If the device fails to connect to Wi-Fi, ensure that the provided Wi-Fi credentials are correct and the network is available.
-
If the device fails to connect to the MQTT broker, verify that the broker URI and authentication details (if applicable) are correct.
-
Check the device's output in the serial monitor for any error messages or debug information that can help diagnose issues.
