WICED Studio Wi-Fi Combo

[StKi_2157971]

- WICED SDK 2.3.0

- ThreadX/NetX Duo, BCMUSI11

When <WICED module> receive the mass data via <TCP-connection>, sometimes <NetX or BCM43362> hang up.

Here is my test diagram.

After researching the capture file, I guess that the problem it is related with <TCP Window resize stuff>(WICED_TCP_WINDOW_SIZE). But, because I dont have the NetX source, I could not debug it any more.

Thanks in advance.

Do you have MCU and/or Wi-Fi powersave enabled?

[StKi_2157971]

No, I didnt use <MCU or WiFi Power Save functions>.Anyway, after I changed the TCP_WINDOW_SIZE as below, the <hang-up problem> never happened. //#define WICED_TCP_WINDOW_SIZE          (14*1024)#define WICED_TCP_WINDOW_SIZE          (2*1024)As I said before, I guess that this problem is related <TCP Window Resize>.Steve K

Cool, so your issue is solved now?

We have the same issue, except that it always occurs. Solution that has worked for Steve K does not work for us. Any idea, what could be the cause?
