The function receiveMessage reads from the serial port, discarding all characters until it receives a STX. Once the STX is received it reads characters, adding them to the message buffer and calculating the check-sum. If an ETX is received, it assumes the next character is the check-sum. Arduino Serial Stx Etx. 7/4/2017 0 Comments. This shows a 9-pin DTE-to-DCE serial cable that would result if the EIA232 standard were strictly followed. Writing and reading data to and from a serial port. For example i would use STX and ETX to frame and send. Browse other questions tagged c arduino intel intel. Now ur ready to go but u need to setup your arduino to perform tricksIn this case i used an app called Bluetooth commander available in google play.The demo sketch is. Add STX and ETX as characters, before getting ASCII. Use (char)STX and (char)ETX, add it to string-only data, and then use System.Text.Encoding.ASCII.GetBytes to the whole string, to get your bytes. The reason for this is quite obvious, but it would be easier for you to understand it yourself (I hope) than explaining it.
Description
Arduino Serial Stx Etx 2
Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several.

On Uno, Nano, Mini, and Mega, pins 0 and 1 are used for communication with the computer. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board.
You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board. Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin().
Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board.

To use these extra serial ports to communicate with your personal computer, you will need an additional USB-to-serial adaptor, as they are not connected to the Mega’s USB-to-serial adaptor. To use them to communicate with an external TTL serial device, connect the TX pin to your device’s RX pin, the RX to your device’s TX pin, and the ground of your Mega to your device’s ground.
