Best Wireless Data Collection Method for STEVAL-MKI109 + MEMS Sensors?

Hi everyone,

I'm starting a project using the STEVAL-MKI109D motherboard with the following sensor adapter boards:

  • STEVAL-MKI247A 

  • STEVAL-MKI240KA 

My main goal is to collect sensor data wirelessly for analysis, rather than being tethered to a PC with a USB cable. I'm trying to figure out the best approach and would appreciate some advice on the options I've considered.

Hi Ardalan,
the purpose of STEVAL-MKI109D is to evaluate the device soldered on DIL24 and the source code is closed.
The best solution to use STEVAL-MKI240KA and STEVAL-MKI247A in "wireless" mode using Bluetooth or SD card (avoiding USB cable and PC), is to select STEVAL-MKBOXPRO as main board.
In this board all requested features are present (see following link: https://www.st.com/en/evaluation-tools/steval-mkboxpro.html)

Best regards.
