Programming the Bluetooth Bee using the Arduino Duemilanove

Products & Technology Bee series & WSN
#1

I just received a Bluetooth Bee and I was wondering if I can use the Arduino Duemilanove (with the Atmeg Chip removed) instead of a separate FTDI cable or board. I was thinking of connecting the Bee’s power to 3.3V on the Arduino, Gnd to Gnd, TX to RX and RX to TX.

I think the Arduino TX/RX operates at 5V if I am not mistaken - is that compatible with the BT-Bee? If not - is there an easy way to fix this?

Many thanks in advance!

Hi Modelar,

I think 5V TX/RX of the Arduino is not compatible with the BT-Bee, and you may try to do like this:(Though I’m not sure if it works)

         5V
          |
          R1
          |

Arduino RX----------------------TX BT-Bee
TX----R2----------------RX
|
R3
|
GND

R1 = 10k, R2 = 1.8k, R3 = 3.3k.

May this helpful to you.

Regards,
