Pi 3b scanner is stopped suddenly after a while #295

Open ghost opened 5 years ago

ghost commented 5 years ago

My Wi-Fi scanner was developed by Nexmon (https://github.com/seemoo-lab/nexmon) based on Raspberry Pi 3B. During capturing the Wi-Fi probes, the scanner sometimes is stopped. The stop time is Mar 26 12:32:15 because we haven't had any data since then.

In fact, when I see the log file of the Pi, there are many warning like this: Could you understand that kinds of warning..? Or my python code makes that the wlan0 of Pi is turned off and on repeatly for changing wifi channel (I want to get the packet with hopping channel). Is it too burden for the Pi??....

You're running out of memory and OOM killer kicks in. Not related to nexmon, check your code

spadejack014 commented 5 years ago

Sir, I cannot run it on my B3. My device is Raspberry Pi B3 , and my system is Raspbian Kernel 4.19. Terminal always displays operation not supported, when I try to run 'sudo iw phy iw dev wlan0 info | gawk '/wiphy/ {printf "phy" $2}' interface add mon0 type monitor'. I'm sure I followed the steps in the README. Could you told me how you did that?

maryannhorton commented 5 years ago

spadejack014. did you resolve the problem? I'm having the same issue. I cross-compiled 43430a1 on a Pi 3B+ and copied it over to the Pi 0, installing in /lib/firmware/brcm/brcmfmac43430-sdio.bin, then I rebooted. I'm not sure about the insmod - I copied the brcmfmac.ko file over to the pi0 but insmod says it's in the wrong format.

DrSchottky commented 5 years ago

@maryannhorton to cross-compile the driver you have to change headers path in Makefile to point at the ones for your target
