Serial sending ascii instead of HEX?

Ok, so I am writing this code where I need to send this message:

Serial.write(0x7E);
Serial.write(0xFF);
Serial.write(0x06);
Serial.write(0x03);
Serial.write(0x00);
Serial.write(0x00);
Serial.write(0x01);
Serial.write(0xEF);

But isn't there an easier way of doing this? Like shouldn't I be able to do this in ascii? or no?

Did you forget ", HEX" ?

(ASCII is a seven bit code, so "0xFF" isn't ASCII)

static const uint8_t MessageInABottle[] = { 0x7E, 0xFF, 0x06, 0x03, 0x00, 0x00, 0x01, 0xEF };
Serial.write( MessageInABottle, sizeof(MessageInABottle) );

Maybe less typing. Probably uses less Flash.

The benefit to your method is that it uses no SRAM.

Do any of those values correspond to ASCII characters?

Would doing something like this be practical?

static const uint8_t MessageInABottle[] = { 0x7E, 0xFF, 0x06, 0x03, 0x00, 0x00, 0x01, 0xEF };
#define Throw_Bottle Serial.write( MessageInABottle, sizeof(MessageInABottle) );
Throw_Bottle

Practical? Yes. Sensible? No.

TL;DR: See post above.

Only if you have a specific reason to use a macro instead of a function. I can address your situation without a response: No, that is not practical. Use a function...

static void Throw_Bottle( void )
{
  static const uint8_t MessageInABottle[] = { 0x7E, 0xFF, 0x06, 0x03, 0x00, 0x00, 0x01, 0xEF };
  Serial.write( MessageInABottle, sizeof(MessageInABottle) );
}

Thanks guys!

If you want the serial to send ASCII, use Serial.print / Serial.println instead of Serial.write ...
