Sf02 range sensor errors

Hi,

I am having issues getting the 14Hz update rate of the sf02 range measurements using sfo2 rev4 hardware despite trying several baurates on the device using the lightware software.

I can read the range measurements at a much lower rate of roughly 0.2Hz with the following with the following error messages

SF0X collection error #0
SF0X collection error #1
SF0X collection error #2
SF0X collection error #3
SF0X collection error #4

Also in debug mode, I get the following errors

SF0X measure error
SF0X collection error #0
SF0X write fail -1
SF0X measure error
SF0X collection error #1

Is there anyone with experience using sf02 (rev 3.0 SN:3648) with the px4 stack on Pixhawk that may have experienced similar issues?

Moses.
