imu data is not proper using ros

[Neel125]

Hello,
I was installed Taraxl SDK in xavier and then after i installed taraxl-ros-package. All topics were work correctly but following imu topic always gives same values like all 0 s.

rostopic echo /taraxl/imu/data_raw

---

  y: 0.0
  z: 0.0
  w: 0.0

and also using below command

rostopic echo /taraxl/imu/inclination

i got below values

---
x: 0.0
y: 0.0
z: 0.0
---

but after that i run taraxl-imu-viewer of taraxl-tools and it gives me some better values like below image, not like all 0 s using ros gave me.

so what am i doing wrong ? or How can i get proper data using SDK ?
please help me.
