Description:

All WCM API return assertion of code snippet 9 (in the docs) are wrong:
https://github.com/Infineon/wifi-connection-manager/blob/master/docs/api_reference_manual/html/index.html#L946-L1218

  if (result == CY_RSLT_SUCCESS)
  {
      ...
      return;
  }

should be

  if (result != CY_RSLT_SUCCESS)
  {
      ...
      return;
  }

THANKS!

Question/Issue:
The question is related to how to disconnect from an access point meanwhile a lot of data is being sent (to me).

What can we help you with?
So, I´m connected to a "server" using udp. I´ve decided to disconnect and call cy_wcm_deinit().
Sometimes this function works as expected and it may take anywhere from 500ms-1000ms to disconnect.
Once in a while it take very long time, 15-20sec. I can see that the underlying threads keep pumping data into the lwIP stack (using debug logs)
Is there someway to avoid this state?

Context

LBEE5PK2AE chip
STM32CubeIde with STM32-Connectivity 1.2.0

Prerequisites

Can you reproduce the problem reliably?
yes

Did you check current release notes for known issues?
yes

If this is not the latest release, have you checked newer releases?

Description:

There are few places in the cy_wcm.c in \COMPONENT_LWIP which call cy_worker_thread_enqueue() to add callback and local variable as parameter, the local variable (cy_wcm_event_t) will soon be invalid after take out by cy_rtos_get_queue for dispatcher from cy_worker_thread_func() in cy_worker_thread.c. this issue will lead unexpected value of cy_wcm_event_t.

Steps to Reproduce:

add register after success of cy_wcm_init():
cy_wcm_register_event_callback(my_call_back_func);

we won't get proper event value such as CY_WCM_EVENT_CONNECTED, etc.

Expected Result:

we should get all valid belong to cy_wcm_event_t event value such as CY_WCM_EVENT_CONNECTED, etc.

Actual Result:

we won't get CY_WCM_EVENT_CONNECTED, instead, it give us invalid value which is out of range cy_wcm_event_t.

Build/Commit:

commit c7c2a01 [c7c2a01]

Target:

STM32H7 with ThreadX+Lwip

Compiler:

IAR 8.50

My fix:
where call cy_worker_thread_enqueue() with non-NULL parameter of *arg, make this local variable as staic, example in
function internal_scan_callback() change
uint32_t scan_status; ----> static uint32_t scan_status;

THANKS!
