Monitor Mode

[Anonymous]

Hello,

I’m trying to figure out if the WICED module can be put into a “monitor” or “promiscuous” mode, where it sends all packets to the host MCU (regardless of the intended destination of the packet).

Thanks for any assistance!

There is no API for promiscuous mode.

Please try WLC_SET_PROMISC ioctl.

You need to add an API like below.

---

uint32_t *promisc = wiced_get_ioctl_buffer(&buffer, (uint16_t)4);

CHECK_IOCTL_BUFFER(promisc);

*promisc = (uint32_t)1;

retval = wiced_send_ioctl(SDPCM_SET, WLC_SET_PROMISC, buffer, 0, SDPCM_STA_INTERFACE);

So, just in case anyone else runs into this - I found the API call after digging a bit:

#include "wwd_wifi.h"

wiced_wifi_enable_monitor_mode();

@dmiya - you were on the right track, but apparently you also need to enable 'allmulti' mode. Check out Wiced/WWD/internal/wwd_wifi.c:1594.

@dmiya, I apologize - After doing further research I've found that monitor and promiscuous mode are very different things. You were correct about the best way to enable promiscuous mode. Thanks for your help!
