RFMON mode for onboard AP6181 WiFi module

Hello! I am a security researcher that uses compact computers like RPI and BPI. I have one BPI-M2 that is interested me with onboard WLAN module capable of hostapd working. This is great thing, that makes BPI-M2 one step further of others. But while hostapd working well, I cant start RFMON mode on this wlan module. Is it not capable of monitoring mode, or just software/drivers are not compatible? Also it would be awesome if oneday there will be a board like BPI-M2 with GSM-lte module mounted.

Monitor mode is not supported on this chip as far as I know. NA with stock or mainline brcmfmac driver.


Sad news, but thank you Igor for info and your work!
