Hi.
I am very new to Platform io.
I did a lot of searching but fail to get any help full answers.
To explain I will use Arduino ide as a reference point.
The Arduino ide versions is 1.xx or 2.xx … in Platform io what is this called Platform or Framework?
From the Arduino Board Manager an ESP32 core (let’s just call it a core for now) can be downloaded , upgraded or downgraded.
What is this core in Platform io Platform or Framework?
See this list for platform version vs. Arduino core versions: platform-espressif32 versions · GitHub
If I understand correctly what you’re asking: “PlatformIO Core” is what makes PlatformIO (aka PIO) tick: a collection of Python scripts. “PlatformIO IDE” is the setup which makes PIO work in the Visual Studio IDE (similar to the Arduino IDE). Frameworks are installable components managed by PIO - there’s a framework which allows PIO to build and run code written with the Arduino conventions and run-time libraries/packages. There are also (many) other frameworks.
I suggest looking around on this website: Your Gateway to Embedded Software Development Excellence — PlatformIO latest documentation - there’s no magic, but PIO’s terminology is different (and closer to “normal” s/w development practice, IMO).
Thanks for the List but this will only help me when I know a lot more about Platform io.
Yes and no , let me explain.
Using Arduino ide , I got a working code with RemoteXY.
The WiFi point connects to my phone,blue on board led is always on.
But there is a problem with the latest esspresif core so I down graded the core to 2.0.11.
Platformio
The exact same code does compile and download to my ESP32.
But my phone does not connect, blue on board led is off.
So in Platform io , should I down grade a Platform or a Framework or a Core to get RemoteXY to work?
Why does the same working code not work with Platform io?
To get Espressif’s Arduino 2.0.11 you have to use in your platformio.ini:
platform = espressif32 @ 6.4.0
@sivar2311
Thanks now I understand the version list you posted.
I will try that.
Thanks it is working.
When I compile the code with Arduino ide , the Blue on board Led is on.
But.
Using Platform io the Led is off.
Which board do you have and what’s the content of your platformio.ini?
My board is ESP32 WROOM DA.
That is what I select in the Arduino ide.
I could only find ESP32 DEV KIT in Pio.
I will test ESP32 DEV KIT with the Arduino ide tomorow and report back also report on the Platformio.ini.
Thanks for the additional support.
The ESP32 WROOM DA module is exact the same as the ESP32 WROOM module except for it’s dual antenna (DA).
The board is a ESP32 DevKitC-V4 and has no onboard LED’s except the POWER led.
When I use Arduino ide with ESP32 DEV Module the blue on board Led does not switch on.
But in my Setup I have 2 fast blinks and that works.
This is my Platformio.ini
[env:esp32dev]
;platform = espressif32
platform = espressif32@6.4.0 ; 6.4.0 for Arduino espressif Core 2.0.11
board = esp32dev
framework = arduino
lib_deps = remotexy/RemoteXY@^3.1.14
How do you blink the led? Please show the code.

I just saw that my ESP32 does not have the --DA.
This is my exact board , picture from suppliers site.
That is a DOIT ESP32 DevKit V1.
Please try the following platformio.ini and test-code:
platformio.ini
[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 115200
main.cpp
#include <Arduino.h>
void setup() {
Serial.begin(115200);
Serial.println("Hello World");
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
Serial.println("LED ON");
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
Serial.println("LED OFF");
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}
Watch the LED and the Serial monitor.
Does it work for you?
Yes it does work.
Print.
LED ON
LED OFF
and the on board Led is flashing.
I used your .ini setup in my code but the Led is off and the Board does connect to my Phone.
I must use a lower Platform version for RemoteXY to work.
[env:esp32doit-devkit-v1]
;platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
platform = espressif32@6.4.0 ; 6.4.0 for Arduino espressif Core 2.0.11
lib_deps = remotexy/RemoteXY@^3.1.14
So the board and the led are working in general.
I don’t know the used library and what your code is supposed to do.
Yes it does work.
The code connects to my phone with RemoteXY app.
I got used to the blue Led always ON with Arduino ide.
I have way over the limit used this post since the original problem was solved.
I will create a new Topic for the rest of my problems.
Thanks a lot I learned a lot so far.
