IWR1443: Please, how do I set the IWR1443 to BPM mode, with both TXs transmitting simultaneously, and 4 RXs receiving? Is there an official tutorial available for this?

Hello.

According to the SDK 2.1.0.4 documentation, the support for the bpmCfg command is only supported for the XWR16xx devices. However, there are way to do this by designing your chirps a certain way. Please refer to the E2Es below for reference.

Sincerely,

Santosh

Thanks for your reply, I have successfully implemented the BPM pattern, as shown in the figure below, I want to use 12 virtual channels to identify the left and right eye, how do I write the code, can you provide some ideas.

Hello.

We do not have any code examples to specific support your use case, but you could try and look for any distinguishable features in the pointcloud between the right and left eye. This is a bit difficult since there aren't many distinguishable features between either, but if you can find one you try and tune the radar to pick up on those differences and analyze those in the application code.

Sincerely,

Santosh
