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.
