Odometry message not displayed with VIO

Jetson Nano

I'm using a VOXL2 compute along with Flight Core V2 as external flight controller.

PX4 version: v1.15.1 (Stable)

The VOXL2 communicates with FC as mentioned in this documentation.

For position hold I have set EV parameter using tracking camera fusing with a Optical Flow with Rangefinder onboard. I'm able to see the odometry message being shown in mavlink console on QGC. Also, I try streaming the message from VOXL2,

mavlink stream -r 30 -s ODOMETRY -d /dev/ttyS1

In voxl-vision-hub I have set the mode to figure_eight. But once, I switch to offboard mode from position mode the drone stays at the same place and does not perform figure 8.

Once I ssh into VOXL2, and check for mavlink status, I get the LOCAL_POSITION_NED but not #331 ODOMETRY message. How can I get that message?

Without that message I'm not sure if VIO inputs from tracking camera would be passed on to FC for fusion on switching to offboard mode of flight.
