Hi.

Everything is still working as expected.
I just tested it.

Are you using VS Code?
Did you set the Serial Monitor speed to 115200 as mentioned in the eBook?
After uploading the code, open the Serial Monitor (by pressing the little plug icon at the button) an press the ESP32 RST button. You should get the information on the Serial Monitor.

Hi Sara,
Yes, I am using VS Code
Yes, I set the Serial Monitor speed to 115200 as mentioned in the eBook
After uploading the code I opened Serial Monitor pressing the plug icon button and press the ESP32 RST button and I can not see the information on the Serial monitor.
In the Terminal I just can see the below:
—Terminal on COM6 | 115200 8-N-1
— Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time
— More details at https://bit.ly/pio-monitor-filters
— Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H
In Serial Port I cant see information
 
Thanks.
 

Hi.
Try to add the following lines to your paltformio.ini file:

monitor_rts = 0
monitor_dtr = 0

Save the platformio.ini file and try again.
 
Let me know if this changes anything.

Sara

I tried several times and it is still not working, I am not sure why because I have my the same code and I followed your instructions

Hi.
Can you tell me the steps you’re taking so that I can try to reproduce them?
Can you send me some printscreens? To share a picture, upload it to google drive or imgur and then, share a link to the file.
What is the ESP32 board you’re using?

Sara

if you have comments please let me know. Thanks

Hi.
It seems you’re using an external Serial Monitor extension. You don’t need it; it can get confused and interfere with the Serial Monitor on the Terminal.
You should use one or the other.
If you want to use the extension that you installed, you need to click on the “START MONITORING” button.
Alternatively, uninstall that extension and use the Serial Monitor icon with together with the Terminal window. After uploading the code to the board and opening the Serial Monitor (on the Terminal Window) you must press the board RST button so that it starts running the code.
 
Let me know if this helps.

Hi Sara,
I did the uninstallation of external serial monitor extension and I used the serial monitor icon with the terminal window and followed up yours instructions pressing the board RST button and starts running the code but still is not working, I attached a new image Terminal 2 in drive link, please take a look on it. Thanks

Can you add the following two lines to your loop(), to check if it is printing the content of the loop()
 

Serial.print("Test");
delay(1000);

 
Try again and see if you get the same result.

Hello Sara,
I tried adding the two lines in my loop() and the terminal is not printing the word Test.
see new image in drive Terminal 3

Hi.
That issue is really strange.
Do you have another ESP32 board to test?
Can you open the Serial Monitor in Arduino IDE and see if you get a response?
It’s hard to tell what might be the issue. It’s either the IDE or the board. That never happened to me before.
 
At the bottom, click on the plug icon and instead of selecting COM 7, select auto. Then, click again on the OTHER plug icon to open the Serial Monitor.
 
Test, just a simple printing program:
 

#include <Arduino.h>
void setup(){
  Serial.begin(115200);
}
void loop(){
  Serial.println("test");
  delay(1000);
}

 
Let me know the results.

Sara

Hello,
Yes, I have 3 different boards to test and with 3 is the same issue.
I opened the Arduino serial monitor and not answer, the code was updated and uploaded successfully but no data in serial monitor yet.
see attached images in the link.
terminal 4 and 5
thanks
 

You can see the boards that I am using in the link as image 1 and 2
ESP32 S3 WROOM 1
ESP32 S3 WROOM 1U

Hi.
I’m not familiar with those breakout boards.
 
Can you remove your ESP32 S3 from the breakout board? That might be preventing the ESP32 from communicating via serial.
You may also need to connect it via the UART port instead of the USB port.

Hello,
I found this information in some websites and I did it in Arduino IDE and know I have the info in the images 6 and 7 in drive

Hi.
I’m not sure how to solve the issue.
I found this discussion: https://forum.arduino.cc/t/e-177-opi-psram-psram-id-read-error-0x00000000-psram-chip-not-found-or-not-supported-or-wrong-psram-line-mode-1204-957-e-177-spiram-sp/1261713/14
