baudrate - Does Bluetooth range increase with lower baud rate?

I am using two Bluetooth dongles for an Arduino project of mine. I am only sending a single int over the connection so it does not need to have a high baud rate.

If I use a baud rate of 1200 will I be able to have more range than if I were to use something such as 115200?

Answer

In my experience, radio modules usually have 2 different baud rates:

• UART baud rate is the baud rate for communicating to microcontroller on the board. Usually, it's adjustable.


• Over-the-air baud rate is the baud rate for communicating via Bluetooth. It's usually fixed.

I've searched through the user manual and datasheet for RN-41, which is the Bluetooth module inside the dongle. I didn't find any indication that over-the-air baud rate is adjustable in this module.

So, I doubt that you will get more range if you configure the baud rate down to 1200.
