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.

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.

Sam,
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
free: 0x%x\r\n", msg ? : "null", mi.arena, mi.ordblks, mi.uordblks,
mi.fordblks));
}
================= End here =======================

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?
