How to configure lightware sf45/b via MATEK CAN Node - L431

Hello,
I have been experimenting with obstacle avoidance using the lightware sf45/b on serial and works fine.
But on trying with a can node (matek can node L431), I am not able to make it work.
Params on CAN node → PRX1_TYPE - 8,
Params on autopilot → PRX1_TYPE - DroneCAN
CAN node firmware version 1.7 (latest stable)

Can someone help me with this?
