Real-Time Data Acquisition with STEVAL-MKI109V3 & STEVAL-MKI217V1 with nRF52840

[Yidi]

I recently purchased the STEVAL-MKI109V3 motherboard and the STEVAL-MKI217V1 adapter board. After some setup, I managed to get the Uni GUI to work. However, I'm struggling to understand how to obtain real-time data from the system for further processing, such as calculating absolute orientation angles.

My ultimate goal is to utilize the IMU sensor on the adapter board along with the sensor fusion software provided by the motherboard. I aim to integrate both components into a device I am designing, which will be powered by the nRF52840 microcontroller.

I would greatly appreciate any guidance or resources that could help me achieve real-time data acquisition and leverage the full potential of the IMU sensor and sensor fusion software in my project.
