Overview

Wireless programming and data transmission can be achieved simply from the BLuetooth.You just need two bluetooths and a USB serial FT232RL . Now ,I will show my test.

Hardware needed


Step

1.A Bluetooth module's key turns to "M" as master ,other's key turns to "S" as slave.


2.Connect the USB serial FT232RL and bluetooth

GND------GND


VCC------VCC


TX-------TX


RX-------RX


For some FT232 shields,you would connct TX to RX,and RX to TX.


3.Open Serial Monitor and set the bluetooth .

You input command " AT+DEFAULT", then input " AT +BAUD8". As the Iduino DUE download baud is 115200,if you want to transmit data ,

you would set same baud for the software.Two bluetooths to do the same action.


Of course ,there are a lot of ways to build communication between two bluetooths ,you can reference Bluetooth manual to build commnnication ,we use most easiest way and don't anything.


4.Follow step 2 to connect master bluetooth and the USB serial FT232RL , and connect slave bluetooth and Iduino DUE Pro like as:


GND------GND


VCC------3.3V


TX-------RX


RX-------TX


5.Power up for the Iduino DUE Pro from battery, programming would fail if you power up from USB port .

The green LED of buletooth is light that means two buletooths communicate , blink is connecting.


Press the ERASS button 2 seconds ,then press the reset button.

Now you can wirelessly program for Iduino DUE Pro.

Please open Aduino IDE 1.5 and selct Aduino DUE(programming port) in board.

We also wirelessly program and transmit data for other boards ,such as UNO,LilyPad,Arduino Pro Mini and so on. But you must set right baud for buletooth.

You can reference :


UNO, DUE , MEGA -------- 115200


ATMEGA328---------------- 57600


ATMEGA168---------------- 19200


DUEMILANOVE328 ---------- 57600


When you download to other boards,you must press the reset button until the TX LED of USB serial FT232RL blinks two times.However ,it is difficult to program for MEGA,bacause the TX LED blink irregularly.You can power up for UNO ,MEGA from USB port.

Troubleshooting

1.IS the green LED of bluetooth light ? It's not,two buletooths don't build communication ,you must set two buletooths again.

2.Are both buletooths setted same baud and suitted to main board?

3.Do you operate the reset button accurately when you are programming ? the DUE Pro is difficult other boards.
