AWR1642BOOST: Integrating AWR1642BOOST with ESP32-S3 ESP-Box for Gesture-based screen control

Tool/software:

Hi,

I'm working on a project where I need to use the AWR1642 BOOST radar sensor to detect gestures and then use these gestures to move between screens on an ESP32-S3 ESP-Box. I’m looking for any sample C code or libraries that could help integrate these two components.

Has anyone worked on a similar setup? Specifically:

How to process the gesture data from the AWR1642 and send it to the ESP32-S3?
Any sample c/cpp code for handling gesture recognition on the AWR1642 since esp32 common base should be c/cpp?
How to handle the communication between the AWR1642 and the ESP32-S3 for controlling the screen transitions?

Any guidance, examples, or documentation would be greatly appreciated!

Thanks!

Hello,

Currently we only have example gesture recognition code for xWR6843 and xWRL6432. You would need to port this example code to run on the AWR1642. There may also be some difficulties in this related to the antenna pattern difference on the EVM. If you are targeting a non-automotive application where 77GHz is not applicable then it would be much better to switch to IWR6843 or IWRL6432. With those devices, these gesture demos will work as it is.

Regarding communication between the radar device and the ESP32, most of our example demos output data over UART in TLV format so that will be the easiest method to facilitate communication without requiring many changes on the radar code side.
