Hi,

I am using a STEVAL-MKI109V3 mother board to evaluate 2 accelerometers :

  • LSM6DSOX (STEVAL-MKI197V1)
  • LIS2DUXS12

I want to use the GUI software UNICO v9.14.6.0 but when I want to connect my device, an error popup appear : "ERROR : The adapter board has not been recognized. The WHO_AM_I register value does not match the device selected".

I have updated the motherboard firmware with the v3.48.3 but I still have the problem with my 2 MEMS boards ...

Can someone help me ?

Hi @thomas Zapparrata​ ,

You have to change the jumpers' position as I indicated you in the picture below:

Here is the steps I followed :

  • Connect my MEMS board (STEVAL-MKI197V1) on the STEVAL-MKI109V3

It is working now, thank's for your help :)

I have exactly the same problem but with the LSM6DSV16X (STEVAL-MKI227KA). I can´t see the image of the solution posted. 

Can I get some help?

It is working now, thank's anyway

 

@Federica BossiCan anyone see the picture? I can't. I have been having this problem over and over again. I am using a STEVAL-MKI109V3 and a IIS3DWB sensor. I have been having the same problem since I bought the sensor. Usually, the problem solves itself by just removing and putting back again the socket onto the development board. However, I have had situations where no matter how many times I plug and unplug the problem won't go away. While the problem is happening, if I plug another sensor (IIS2DH) it works just fine. I have already updated the firmware twice. Can you please tell me a solution for this problem? I have add situations where I wasn't able at all to use the sensor and a day after it works fine. It is really not reliable at the moment. Thanks in advance.

Hello @Eduardo1 ;

I am encountering the same problem with regards to the same board. I would greatly appreciate it if you could kindly share the solution you have found to resolve this issue.

Hi @FKara.3 , @B3r ,

Please can you share a picture of your STEVAL-MKI109V3? So that I can check if your jumpers are ok.

Thanks.
