Change baud rate of Bluetooth V3 using Arduino board

Hi,

is it possible to change the baud rate of the bluetooth V3 module using the serial interface of the arduino board?
Like cross connecting Rx/Tx of the board and the module and send the required bytes?

Thanks

Because the atmega8u2 chip is working as a USB to TTL converter. And programming interface(TTL pins) is connected to the Arduino D0/D1(TX on atmega8u2 to RX on atmega328). So you could directly use it to work as a USB to TTL converter temporarily.

how to use an arduino board and program to change the baud rate because i have no of usb converter..
please explain in detail..thanks a lot

I have a Romeo board. So option 2 doesn't work.
Do you think it works with soft serial? (is it normal serial communication at all?)

Do you have any chance to test it? I think a lot of Bluetooth Module V3 owners would be glad about it.

Thanks
Robert

I suppose it's possible, but you would need to:


A. Write a sketch to do it for you


or


B. If you have a DIP package Arduino (the kind where you can remove the Arduino chip) and just talk to the bluetooth module directly through the USB port.


Here is a post that confirms this:
