#include <Arduino.h>
const int ledPin = GPIO_NUM_21;
void setup() {
pinMode (ledPin, OUTPUT);
}
void loop() {
digitalWrite (ledPin, HIGH); // turn on the LED
delay(500); // wait for half a second or 500 milliseconds
digitalWrite (ledPin, LOW); // turn off the LED
delay(500); // wait for half a second or 500 milliseconds
}
In GPIO21 there is a LED, after runs this program nothing happens!
Can you see that ?
[env:nina_w10]
platform = espressif32
board = nina_w10
framework = arduino
Try
const int ledPin = D21;
What happens now?
Hello friend!
Nothing happens too!
then set ledPin = 21 directly?
oO Did you set the required jumper to connect IO-21 to the LED?
yes i did! Connected the jumper!
I uploaded the exact same Nina W10 code with GPIO_NUM_21 and platformio.ini to my ESP32 development board, and it blinks IO-21 without a problem.
(Not suprising since the Nina W10 is also just a ESP32 target with the same code running on it, so a change in development board doesn’t make difference here…)
So I strongly sense you have a hardware issue. Please check if you see a 3.3V / 0V switching on IO-21 on J2 using a multimeter (or a LED with resistor). Lower the frequency if necessary.
Thanks to test it!
Looks that is some partition problem that make the application not runs on NINA W, because i remember that on ARDUINO IDE works nice the blink!

works very nice the program on NINA W.
Can you verify how to modify manually the partition parameters on platformo arduino framework to nina w ?
Please, see if possible change the partion parameters in the plataform.ini to nina w
Thank you friend!
I don’t see how partition tables would change anything. They just change the sizes / available space for the program (APP0, APP1), SPIFFS etc. If the firmware compiles on both versions, it can’t be the problem, especially not for this blink program.
I’m stunned why a simple blink should not work with PIO but with Arduino IDE. Can you upload both produced ELF files? (for PIO: .pioenvs/ninaw10/firmware.elf)
yes!!!
Of course! 
Hi,
I tested in other machine (i instaled platformio) and occurs the same problem! On ARDUINO IDE works, but on PLATFORMIO Arduino framework not runs!
maybe this help you

Does flashing succeed with PIO? (‘SUCCESS’ message?)
i am not in Home now! I am in the classroom! send a picture of (‘SUCCESS’ message?), and i will compare when back home

Hm OK so it uploads correctly. I’ll check the ELF for differences in code…
