How Can I get IMU RawData?

I’m using NRSDKForUnityAndroid_1.7.0.

I’m trying the NRSDK Scripting API below, but I can’t find the t-class NRIMUDataProvider to get the IMU from NRSDKForUnityAndroid.

How can I use NRIMUDataProvider?

This is for the same reason replied in another thread: Can I use GrayCameraDataProvider Class in NRSDKForUnityAndroid_1.7.0

Unfortunately, the IMU raw data is not officially provided by NRSDK right now. Instead of implementing your algorithm with raw IMU data, however, you can expect better SLAM features from Nreal, which we’ve always been working on.

Thank you!
