Using sparkfun esp32 div kit
With Ardino,
Ardino board manager
Using "SPARKFUN ESP32 THING",
#include <WiFi.h>
#include "Esp32MQTTClient.h"
Using the header file of
I am communicating with WINDOWS AZURE IOT.
This time
Replace with ESP-WROOM-02U (4MB),
I am trying to make the circuit configurations similar and communicate.
At this time, can I continue to use the Ardino program?

Yes, Wroom modules are also programmable using our Arduino SDK.

But you know that ESP-WROOM-02U is esp8266?

Let me clarify my answer a bit as well: As long as the module has an ESP32 in it (like the one in the post above me) you can program it with the ESP32 SDK. (If you have a module with an ESP8266, it's also programmable using an Arduino SDK, but the ESP8266 and the ESP32 SDK may not be source-compatible.)

Here are some things to check in this matter: Currently, wire according to the following drawing,
Even if you try to write a program,
I can't write.
Is there a wiring problem?

One thing I could see is that EN needs a pull-up to work.

Thank you very much. I'll try

Feedback

Make the following wiring
Without floating the ESP32,
After fixing to wood
It worked.

State at the time when it does not work
〇 Part of GND is not wired.

〇 ESP32 is connected only by electric wires,
It was floating.

〇 About writing
Attached figure: Press the IO0 switch during writing, and after writing,
At the start of the program
By pressing the EN switch
It works.
