IWR6843ISK-ODS: About RF sensor UART output TLV data extract

Jianhong Lin

Part Number: IWR6843ISK-ODS

Hi all,

We are experiencing an issue with the UART TLV output format while developing our application using IWR6843-ODS.

We would like to use the radar toolbox-gesture recognition example project for our application, but the task has some differences, so we need to retrain a model.

Therefore, we want to use this project to collect data (we only need the model's input feature). The user guide mentions that we can collect model input features using the UART serial port (to obtain model output or model input features).

We have loaded the serial data (shown as an image), but we couldn't extract information from it. Our question is how to extract data from the bin file and what header type represents the model's input feature.

可以看一下C:\ti\radar_toolbox_1_00_00_26\source\ti\examples\Gesture_Recognition\Gesture_with_Machine_Learning\docs\Gesture_with_Machine_Learning_users_guide.pdf文档里的UART Output Data Format

您好，我已經有參考此文件了，但仍然不太清楚是發生甚麼了，我擷取到的封包數量是192個，扣除文件中寫的Frame Header剩下152個封包，但這根本無法整除後續的資料長度(Header+value 48個封包)，故想了解這是發生甚麼問題，請問是我操作還是理解有誤嗎?

另外，我也根據文件嘗試尋找相關的Type封包內容，但無法在我接收到的封包列內找到相關資訊，可否麻煩您詳細說明此部分嗎?

Gesture_with_Machine_Learning_users_guide的關於數據類型註解內容如下:

% TLV Type: 1020 = Point Cloud, 1010 = Target object list, 1011 = Target Index, 1012 = Target Height, 1021 = Presence Indication
