IWR6843AOP: people counting use WIFI transfer data

Part Number: IWR6843AOP

Hello,

I had a problem when i use WIFI transfer data,the format of the data received by my computer is incorrect.

I read this user guide (C:/ti/mmwave_industrial_toolbox_4_12_0/labs/People_Counting/WiFi_Data_Transmission/docs/3d_people_counting_with_wifi_user_guide.html).

I think the problem may be caused by changing the original protocol,so where can i find the source code of these three file(C:\ti\mmwave_industrial_toolbox_4_12_0\labs\People_Counting\WiFi_Data_Transmission\prebuilt_binaries).Maybe i can change the protocol and rebuild bin file by myself.

    Hello,

    We will not be able to provide the source code. However, if you could please be detailed in the error, we can investigate the bug and provide a fix in a future update.

    Hello,

    Picture1 is the result of demo code(C:\ti\mmwave_industrial_toolbox_4_12_0\labs\People_Counting\WiFi_Data_Transmission\prebuilt_binaries).

    Picture2 is the result of my code,i only send out header and the data i need.

    All the data i sent is mixed up,and some data length is incorrect.What can i do for this?

    Hello,

    I found the problem.The packetLen of my code is wrong.I can receive correct format of the data.

    Now i have other questions,i send out data each frame,but the received data shows that WIFI board send out data each two frames.Is this correct?

    Is there a description of these data sent from the WIFI board?They looks like header but header only 48 bytes.

    Hello,

    The examples use prebuilt binaries for two CC3235 boards: one CC3235 is a transmitter and the other is a receiver. These are simply examples and we have not intended to distribute the code. 

    The way the packets are sent are one at a time. So every mmwave packet is sent in a transmission. Instead of building your own system, I would recommend using our prebuilt examples as a bridge.
