I’m using a Lolin ESP32-S3 mini and I have two weird issue that doesn’t happen with ESP32.
to use the Serial.print() on the ESP32-S3 I need to add this build_flags:
to my platformio.ini.
If I add this flags I can correctly print to Serial but the microcontroller doesn’t “boot” automatically.
If I connect the microcontroller to a power bank, the sketch does not start,
if I connect it to the usb the sketch does not start until I open the Serial monitor.
how this is possible?
I have a PC software that sends messages over serial. I read this messages on the ESP by using the Serial.read() function.
This works perfectly well on ESP32, C3 and S2 but not on S3.
On S3 I have a weird behaviour. If I sent 10 message from the PC to the ESP I receive only 5 message, if I send 20 message, I receive only 10 message.
I receive half the message I send from the PC. Why S3 is so weird?
Hope that someone can help bringing some lights on this weird issues
