Hi,

does someone know where the baud rate is defined? I look in ArduinoHardware.h, and in the package rosserial_python in serial_node and serial_client. I have changed them but default is always 57600. And yes I know I can define it: rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0 _baud:=250000

And second: Is it correct that it works with different baudrates, not just one? And what's the maximum baudrate for an arudino zero?

Thanks

The baud rate default is defined in rosserial_python/serial_node.py.

baud = int(rospy.get_param('~baud','57600'))

As you rightly say, using "baud" as a argument with rosrun or as an argument for launch files is the best way to set this.

Unfortunately I don't know what the maximum baud rate is on the Arduino zero, but you could experiment with this using the Arduino IDE.
