[question] is it possible to enable monitor mode /packet injection on wcn3990

[MOHAMMAD RASIM]

Hi,
I have a device that has the wcn3990 wifi chip that uses the ath10k_snoc driver, i tried to put it in monitor mode, the "set monitor" mode command succeed but can't get any scanning working after that, does the chip support such mode?has anyone tried monitor mode with this chip or other snoc chips?

Regards

I doubt that WCN3990 firmware supports monitor mode, though just
guessing here.

Some people has got monitor mode working under android ( different driver, qcacld-2.0, and qcacld-3.0) with these kind of chips: https://github.com/kimocoder/qualcomm_android_monitor_mode/


Some older chips (wcn3680  think) even supported packet injection(using the older  qcacld-2.0 driver).

Commits in the newer  qcacld-3.0 driver (that supported the wcn3990) did contain hints that monitor mode and packet injection should work.

So maybe the firmware does support it?

Maybe it does then, I don't know really. My response was just based on
my past experiences with mobile chipsets.

 So after testing and following this: https://gitlab.com/sdm845-mainline/linux/-/issues/45#note_2073028221

It seems it is possible but unstable, I was able to capture some traffic one time only, after that every time I try to capture in raw mode the firmware crashes or fails to load some file like board-2.bin


[  440.761935] ath10k_snoc 18800000.wifi: failed to fetch board data for bus=snoc,qmi-board-id=0,qmi-chip-id=0 from ath10k/WCN3990/hw1.0/board-2.bin
