Hi, I have a problem with making an esp32cam server with image transmission. When I upload the code that is in the arduino.ide examples such an error I get as below in the screengrab. I changed the voltage from 3.3v to 5v and the baud rate from 115200 to 9600 unfortunately with no change the same error is displayed.
.
The terminal displays this error:
Sketch uses 1431465 bytes (45%) of program storage space. Maximum is 3145728 bytes.
Global variables use 65360 bytes (19%) of dynamic memory, leaving 262320 bytes for local variables. Maximum is 327680 bytes.
esptool.py v3.3

A fatal error : Failed to connect to ESP32: No serial data received.
