@jlinktu I don't know what it should look like, but my compiled bcm4375 (s20 version) firmware (with patch) hasn't wlc_monitor_attach if check with strings command though compilation finished successfully |
Not sure what I am supposed to do with this information... thank you for telling me, I guess. |
@jlinktu Monitor mode finds nothing, maybe because of this |
Some assume I'm a wizard 🧙🏻♂️ who magically knows what is happening on your local inner machine - surprise: I'm not. You might help the situation by answering the following questions:
The more detailed and precise your answers are the easier it is for me to help you out. |
@jlinktu Sorry for that, I just thought you know what I was meaning about, cause thehe is many issues with that. |

I write this for launch monitor mode: Nexutil -m returns "monitor -2147483646" after -m2 parameter and "monitor -2147483647" after m1. Tcpdump also captures nothing |
Try setting a channel before enabling monitor mode.
Does this change anything? |
Also no result (channel also stuck on 0) |
What does reading out the channel return? |
Says "chanspec: 0x1006, 6" and nothing capturing |
Well, I guess matthias has tested the patch before committing and pushing it, so I assume it will work somehow. Maybe not directly with |
@jlinktu I was busy in last several days. Today I checked all that you wrote. 5ghz is also same as 2.4ghz. After that command: |
This just means that the bus is idle for a specific time duration. But maybe you have to disable power saving. You could do this by adding the following calls set_mpc(wlc_for_chanspec, 0);
set_mpc(wlc_other, 0); here: I don't think that Exynos makes the difference. Its the same WiFi chip. If the above still doesn't help, there might be a compatibility issue between the firmware and driver. |
I'll try to figure out how find target patching addresses in new firmware. I hope I will can do that. So, I use nexmon rom extraction tool, it works but fills the binary with these errors: ioctl -95, I also tried bcm4389 extraction tool, same result. Will I need bcm's rom? |
You can find a ROM dump of the

@jlinktu I added printf into firmware for some debug but |
If the firmware doesn't support the |
Could you update patch for new binaries at S20, N20 series? From OneUI 3 even with permissive SELinux we cannot use monitor mode. please update
