Vision Position Estimate not working


I am using vision_to_mavros/ at master · thien94/vision_to_mavros · GitHub for position estimates. For initial few seconds, I am able to see the packets but after that VISION_POSITION_ESTIMATES frequency decreases to 0.

I have added all the parameters mentioned here: Intel RealSense T265 — Copter documentation

Just the VISO_TYPE is not there in ArduRover

Does anyone have an idea how to get it working?
