Obstacle Avoidance BR - Lightware sf45/b not working

Hi - I can get simple avoidance to work - i.e. stops at an obstacle… but when i disable this and enable OA BR… it does not have any effect on my rover. I have spent weeks trying different settings…

(i had RPlidar A3 working ok but have since swapped that out for the lightware sf45/b)

Here are the bin files… i wasn’t sure which one has the goods…

Can anyone help …please.
