The write() command sends a raw byte across the serial line
print() , on the other hand, will try and interpret the number and send the ASCII-encoded version of that number.
@ruilviana!
Serial.print() (link)
Serial.write() (link)
Not In that case since the type of c is char
char c = client.read(); // read a byte, then
Serial.write(c);
So it would do what’s expected
It’s more of a performance idea as basically when you print() a char it calls write()
size_t Print::print(char c)
{
return write(c);
}
so by calling write() directly you skip one indirection in the function call stack (which probably the optimizer would catch so it’s a moot point)

Yes, I was agreeing with you, showing a link to the data pages.

I am agreeing with the doc too but here print or write would do the same thing as print just calls write… so just call write yourself and dont rely on the optimizer to save an indirection
When you say "print just calls write", are you implying that, at least in certain cases, "print()" is functionally the same as "write()"?
I gave the code of print in post #4 when the type of the parameter is a char. You can see it’s just calling write
Of course other variants of print exist and will ve called depending on the type of the parameter. If you pass an int for example that’s when the conversion to the ASCII representation happens
If you click on the link you can see the source code for those variants too
