To double-check, are you sure the problem is not in the Arduino sketch? Python exhibiting the same behavior tips to that IMO. A quick search yields a similar issue due to using an int for larger baud values: https://arduino.stackexchange.com/questions/67568/serial-port-fails-with-speeds-greater-than-19200 > On Jun 27, 2025, at 2:51 AM, Jim Ruxton <[email protected]> wrote: > > > I'm not clear how this works. Because if I change the baud rate it definitely stops any communication between the laptop and the Arduino so baud rate must have some meaning in this case. I also tried using a python program I wrote and got the same behaviour of working up to 19200 then stopping so I don't think it's an issue with Pure Data.
