Part Number: IWR1642BOOST
I'm using IWR 1642 BOOST for people count application. I'm checking the tlv data for target x,y positions.
Sensor seems to function well in the beginning. After a few days or a week, it is sending -nan values for posx,posy values.
Therefore the people count seems low and there is no target seen on matlab screen except point cloud data. When the sensor has been rebooted, it functions normally again (for a week may be ).
I'm receiving the tlv data and printing it in my program. Here is the sample output.
Can anyone tell me why is this occurring and what is the solution to this problem?
We will look into this - it may take about a week.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Justin Curewitz:
The IWR1642 version of the demo uses an old version of GTrack. To get the latest version, which should remove this issue, please ensure you have the latest mmWave SDK (126.96.36.199), and recompile the demo using the GTrack library from this SDK. GTrack is a library, so you just need to change the linker file path for GTrack. This can be done through project properties in code composer studio.
Thanks for your quick response. I will try the fix you stated above and test for about a week or more and then update you.
Is it okay to just link the Gtrack library from latest sdk (or ITB) into the demo code from previous version of sdk (or ITB) as you suggested?
Or is it better to build the demo code from the latest sdk or ITB which has this GTrack fix?
Now i have just tried the first method as you suggested but will this lead to any performance issues?

You can use the prebuilt GTrack lib binary in the SDK. This is found at:
