Description

It is compiling and working perfectly when I compile it with arduino ide 1.8.19 and esp32 board version 3.1.3.
So I connect the lcd display and reset the sketch and i see all the debug messages.
If i disconnect the lcd display and reset the esp32 board, the sketch is working and there are no extra messages on the serial monitor.

If I upgrade the esp32 board to version 3.2.0 and recompile the sketch, then it is working with the display connected.
If I disconnect the display and after reset, then I get non stop messages on my serial monitor.

like:

15:05:34.739 -> E (2056) i2c.master: I2C hardware NACK detected
15:05:34.739 -> E (2056) i2c.master: I2C transaction unexpected nack detected

15:05:35.820 -> E (3098) i2c.master: i2c_master_multi_buffer_transmit(1186): I2C transaction failed

and I did'nt had that with esp board version 3.1.3

Is it possible to check that issue and change the board manager so that we don't have that problem.
Many thanks.

Sketch

using:

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcdsetup(0x27,16,2);
void setup(){
  Serial.begin(115200);
  delay(2000);                                        
  Serial.println("");
  Serial.println(__FILE__ "  " __DATE__);

  lcdsetup.init();           // initialize the lcdsetup
  lcdsetup.backlight();
  lcdsetup.clear();
  lcdsetup.setCursor(0, 0);
  lcdsetup.print("Opstarten");
}
