Hi, lucky-you

Thank you for the question and I think your other thread has the same problem.

According to your description and the picture, there may be some wrong during the communication between Position2Go and PC. There several possible reasons for this problem and you can try to solve it:

1. Please confirm the connection between the Demo board and PC. You can open device manager, it will show as below if PC can identify device and you can run Radar Fusion GUI with the Demo board.
   
2. Please try flash the firmware in Radar Fusion GUI before using the MATLAB SDK.

Hope that will help you,

Neo Lu

I'll try it  when i back home.but i think  my sensor  was  linked  and  the GUI  ran  yesterday.I'll  try it again then.

OK, keep on communication if the problem still there.

I've found  the problem  some minutes ago.it's blame  the version of matlab,my  computer  installed  2021b matlab .I  uninstalled it then and  downloaded  2018b  matlab.Then  the problem is  solved.

Thank you for your reply!
