ive been messing with this code, and ive been having so trouble displaying whats being stored in 'inChar' correctly. so if i typed in "hello" on my phone and sent it via Bluetooth. i want the ardunio to display "hello" on the serial monitor. currently i can only get it to display 1 character at a time (displaying vertically)

char inChar;
char inData[24]; // Use whatever size you need
byte index = 0;

void loop()
{
   while(Serial.available() > 0)
   {
      inChar = Serial.read();
      if(index < 22)
      {
         inData[index++] = inChar;
         inData[index] = '\0';
      }
      
      Serial.print(inChar);
   } 
   // Use the data in inData, then reset

   inData[0] = '\0';
   index = 0;
}
