Configure ArduPilot for 256000 baud UART?

I am using a lidar sensor that communicates at a 256000 baud How can i changed the baud of the serial1?

Hi Edd,

If you want to change the serial’s baud rate, you can do this through a Mission planner. You need to change the following parameters:

The protocol depends on the device you are using. Lidar360 requires N to be set to “11”.

You can find more information in ArduPilot’s documentation.
