Can anyone please send a reference note of IoT communication between Arduino Cloud and ESP32-s2/c2/s3/c3?

Thanks for your efforts.

IoT Cloud insists my ESP32-S2 is an ESP32

I put the words "reference note of IoT communication between Arduino Cloud and ESP32-s2/c2/s3/c3" into an internet search engine and get several results like; [How to Connect an ESP32 to the IoT Cloud : 8 Steps - Instructables] (https://www.instructables.com/How-to-Connect-an-ESP32-to-the-IoT-Cloud/)
give it a try.

Arduino Cloud is using an outdated version (1.0.6) of the ESP32 boards platform from before the time the support for these new microcontrollers was added. So you won't be able to compile Thing sketches on Arduino Cloud for those boards.

You could try using the standard Arduino IDE to compile your Thing sketches. You only need to do the initial generation of the Thing sketch on Arduino IoT Cloud. After that, you can download the sketch to your local computer and use it in the IDE from there on. I have no clue whether the libraries are compatible with the new ESP32 chips, but portability is a hallmark of the Arduino framework, so it certainly is possible.

Thanks for your response, Thank you very much.

I tried to upload the Arduino IoT Cloud sketch into ESP32-S2/S3 But it is showing warning errors?

Can the board(esp32-s2/s3) run with waring errors while uploading the sketch?

Anyone knows could you please help me, Use API keys how to subscribe or publish the data using Arduino IoT API keys.

Here is a link to the ESP32's MQTT API, ESP-MQTT - ESP32 - — ESP-IDF Programming Guide latest documentation (espressif.com). I've been unable to get the API to work under the Arduino IDE. I use PubSubClient, which works OK. The ESP32 MQTT API works under the ESPRESSIFF IDF. Good luck.

I have deleted your other cross-post @vamshi43286.

Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please take some time to pick the forum category that best suits the subject of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide you will find at the top of every forum category. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Thank you so much, Here is the source link Basic Arduino API GET example - need one arduino to read another via API - #5 by mattmakerunleashed

But I'm new to Arduino, Can you please look into and help me.

Thanks for your efforts.
