Baud rate between for HC-05 Bluetooth to PC transfer

My Arduino uno code runs at 38400 baud. It outputs some variables, that are a product of of sensor data with calculations done to it, to my PC through a HC-05, so I can view it in the serial monitor.

My question was: Do both Arduino and Bluetooth need to be at the same data rate? I know the Bluetooth modules baud rate varies by its mode (38400 for AT mode, 9600 for default, which I've read is good for data transfer.)

I would prefer to match the rate of the Arduino itself as I'm assuming distortions would creep into output when the data rates don't match.

You're dead right about that.

IF you really have set Bluetooth to COMMUNICATE at 38400, then set your serial begin command to 38400.

If not, then leave both at 9600, which is probably sufficient.

Thanks for your response!
