I understand what baud rate is, but I am trying to find out if there is ever a reason to use a lower baud rate (9600) vs. a higher baud rate (115200). Assuming the devices that the data is being transferred between are capable of the higher speed (115200) why would anyone ever use a lower baud rate? I see many sketch examples that by default set the baud rate to 9600 and it makes me think there is a reason why people are using the lower rate. Is the data more reliable at lower baud rates, less prone to communication errors?
Thank you in advance.
