Hi all. This is not really, really, really important but it would be good to get rid of it.
When I upload a sketch to the ESP32, on the serial monitor, I see a set of strange characters just after platformio finishes. Then everything looks fine, but this “process-upload-end” is odd. Does anybody know what is the reason for that and if there is some way to fix it? Thank you in advance.
The symbols are like this:
*--- Terminal on COM8 | 115200 8-N-1
--- Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time

Which baud rate are you using? On boot, ESP32 boards output something like this:
If you are not using 115200 baud, this will be corrupted, resulting in odd symbols.
I had not tested it but, yes. I have just teste with a newly created project,
#include <Arduino.h>
// put function declarations here:
int myFunction(int, int);
void setup() {
// put your setup code here, to run once:
int result = myFunction(2, 3);
}
void loop() {
// put your main code here, to run repeatedly:
}
// put function definitions here:
int myFunction(int x, int y) {
return x + y;
}
and the result is:
— Terminal on COM8 | 9600 8-N-1
— Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable, send_on_enter, time

Hi peter. Yes, I am using 115200 baud. In fact, after this strange starting, the rest of received data look fine. Yo can see it in my first post, when I write, from the sketch, the value of temp and humidity.
The platformio.ini file has this line:
By the way, I have tested to close de first opened serial port monitor in platformio, and open a new one while the board is still connected and “working”. It only shows this (I think everything is correct):
--- Terminal on COM8 | 9600 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
But, if while being connected, I press the tiny reset button, I get this “new” line:
@�␄␃���L�␓���␅B#�#␟"␛a�
Of course, the symbols appearing each time are different.
