974 + FUNCTION NAME: void DemoAckSent(uint8 success)
975 +
976 + DESCRIPTION: the function is called if the ACK packet sent correctly
977 + or there was a problem to send it. It reports the result
978 + on the LCD and to the UART.
979 +
980 + INPUT: success - status of the ACK transmition (TRUE/FALSE)
981 +
982 + RETURN: None
983 +
