CYW4343W monitor mode AN

[JuXu_4372481]

Hi There,

Any one can provide an application note about how to enable the monitor mode of CYW4343W?

Currently, I am taking an project to use the monitor mode, however I encountered a problem about bus data credits runout problems, as I need to change the channels during the monitor procedure.

What is the host you are using with 4343W? (Is it a WICED based device?)

Documentation related to monitor mode can be found in CYW43XX Technical Information - WL Tool for Embedded 802.11 Systems​

The host MCU is imxrt1050, our SDK has ported the 43xx drivers

You can try the following sequence

1. wwd_wifi_set_down
2. wwd_wifi_enable_monitor_mode
3. wwd_wifi_set_up

or the equivalent in wl tool. Please let me know if that works out for you.

I did it by following your suggestions, but this time the monitor mode not work as no frames received by enabling the monitor mode after turn wifi down. Do you have other suggestions?

Are you checking with the snip.packet_filter example or some application of your own? If you are trying out on your own application, I would recommend testing out the packet_filter example and see if you are seeing any frames.
