Monitor mode on raspberry pi 3b+ #384

Open itspa1 opened 4 years ago

itspa1 commented 4 years ago

Monitor mode on 3b+ with the nexmon patch seems to be crashing every now and then, and the only solution to it seems to be rebooting the device, I've also looked at the issue in raspberry pi itself, but I'm hoping this might an issue with the patch also.(since it says firmware halted)

after some time running it on monitor mode, this is what I get on dmesg and it stops responding

@Impeekay what power supply are you using? I've had issues with bad power supplies and power banks.

@zeroby0 no i did check the power supply, I've plugged it directly to the power. Also the issue is it runs for certain hour's and then stops.

itspa1 commented 4 years ago

@DrSchottky, thanks for your reply, yes I did check that issue before raising an issue. I'm sure and I have confirmed that I have the correct patches built and installed. Hence, raised this issue here.

DrSchottky commented 4 years ago

@Impeekay We need to know more about the context: What are you doing? Only monitoring or also injection? With which sw? What's in your forensics file? Kernel and FW version? And so on...

itspa1 commented 4 years ago

@DrSchottky , that is the thing that is bothering me, the forensics file does not exist in mine at all.
