IWR6843AOP: people counting use WIFI transfer data

Part Number: IWR6843AOP


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. 

  • I got it,thanks for your reply.
