I regret to inform you that we haven't tested the monitor mode of CYW43907 and we won't recommend using monitor mode. Also, if there is any problem arises while using the monitor mode, it would be very difficult for us to help you in future.
We recommend 43455 Wifi radio module which has 800KB SRAM. Kindly refer below document to know more about 43455 and let us know if 43455 chip is feasible for your project.
Apologies for the inconvenience caused.
Thank you for the response. It looks like 43445 is a standalone WiFi link controller that does not have a core dedicated to hosting a separate application. Is that correct? What drew me to the 43907 is the embedded application processor.
If this is correct, can you suggest a Cortex-M or Cortex-R based application processor that has an SDK with existing driver support for 43455 part you recommend?
You're right. 43455 is a standalone radio WiFi module that does not have a dedicated core to host an application.
We have checked internally and unfortunately there is no existing driver support with SDK for 43455 that matches your requirement.
Sorry for the inconvenience.
