I need to send HEX code to UART.
Is it possible with Arduino?

I tried many ways to do it, but w/o success.

The picture what I need to send in attachment.

How to send exactly this data to TX output of Arduino?

const char command [] = {0xAA, 0xFA, 0xE1};
const int commandLen = sizeof (command);
Serial.write (command, commandLen);

AWOL:

const char command [] = {0xAA, 0xFA, 0xE1};

const int commandLen = sizeof (command);
Serial.write (command, commandLen);

Thank you!
