How to increase px4flow rate over mavlink


px4flow is connected to pixhawk via i2c and pixhawk is connected to my computer via telem2 port using ftdi board.

I’m receiving the px4flow optical flow mavros message on the computer, but it has only 10hz. It seems like optical flow is calculated on px4flow board with 150hz. Do you have any idea what blocks the rate? or is there any way to increase the optical flow rate on my computer?

Thanks in advance!
