    3.3.1 snip.scan

    Ch-_2119361

      Hi all,

       

      I found that the snip.scan example does not work well. It hangs during scanning and sometimes resets itself. I am using WICED SDK 3.3.1.

       

      When switch back to 3.1.2, it works just fine.

          Hello,

           

          May I know what platform you are using so I can try to recreate your problem?

           

          Thanks,

            Hi @abuch,

             

            I am making my own product with BCM43438 A1 chip + STM32F205 MCU but I also tried with BCM943341WCD1 board, it has the same problem.

              BCM943362WCD4/BCM9WCDPLUS114 on SDK 3.3.1 also have same scan hang issue!

              And SDK 3.1.2 scan have memory leak issue too!

                Hi Jone,

                Can you point out the place of memory leak in SDK3.1.2 scan?

                Thanks.

                  SDK 3.1.2

                  The amount of free memory reduced after a couple hours run of scan!

                  And hang after run of memory!

                    Hello,

                     

                    Where is the memory leak occurring? and how did you come to that conclusion?

                     

                    Thanks,

                      Attached log file , show the memory reduced,

                      But it occurred infrequently!

                        Hi Jone,

                        Which functions are you used to print below line?

                        Count [1]: Total 0x460c unused:0x2 allocated: 0x35b4  free: 0x1058

                         

                        Thanks.

                          Below is used to print memory info.

                           

                          ================= start here =======================

                          #include "malloc.h"

                           

                          volatile struct mallinfo mi;

                           

                          void wiced_thread_mem_info(const char *msg)

                          {

                              mi = mallinfo();

                              WPRINT_APP_INFO(( "\r\n%s: Total 0x%x unused:0x%x allocated: 0x%x

                          mi.fordblks));

                          }

                            Here is my log, I am not sure but it seems that it stops if "HP-Print-D8-LaserJet 1025" is scanned. But SDK 3.1.2 has no such problem.

                              Hi Broadcom team,

                               

                                Do you have any update about the scan hanging issue on top of WICED 3.3.1?
