Libraries
1

ESP32.
However, for aws freertos, it seems I need a certificate (demo) to connect to wifi.

Please tell me how to do a simple wifi conecting and connecting to a local mqtt server.

The URL is below.

mqtt://localhost:1883

This demo shows how to connect to a local MQTT broker unencrypted - FreeRTOS/FreeRTOS-Plus/Demo/coreMQTT_Windows_Simulator/MQTT_Plain_Text at main · FreeRTOS/FreeRTOS · GitHub

This is for Windows Simulator - you can use this as a reference and do the same on ESP32.

Thanks.

Thank you for your reply.

Where exactly is this described in this?

4

Have you seen the documentation here?

5

I have checked.
Thank you very much.

Can I refer specifically to “Subscribing to a MQTT Topic”?

Also, are there samples that actually connects to mqtt bloker on macbook localserver as aws freertos instead of freertos?

What do you mean by aws freertos? The example I mentioned above uses our MQTT client library to connect to MQTT broker which can very well be the broker running on your local laptop.

Yes, it is for windows. You can use this as a reference to do the same on any platform.
