Failed Network Scan

[fbbfnc]

First of all thank you very much for you work. I'd like to help you if possible.

Is there a way to enable debug mode in the XCode project? By the way, my issue is the following message when i press "Scan": A network scan could not be completed at this time.

I've just tested it on 3 different devices and it worked on each one.

Make sure this file exists: /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Apple80211

In regards to debugging, it a little more difficult bc it needs to run as root:

Option 1: Launch app as root (sudo su) in Terminal, and debug/print with [@"example" writeToFile:@"/dev/stdout" atomically:NO encoding:NSUTF8StringEncoding error:nil];

Option 2: in xcode select manage schemes -> launch as root, and NSLog() as normal

If there‘s no further follow-up, I‘ll close this issue

I'm getting the same error, (on a 2019 MBP) I do have the Apple80211 file, and I have tried launching it via the Terminal with sudo su, as well as launching through Xcode as root.

All the console printed out was the following:

@ajkblue It should now print a more detailed error

Alright, I just updated and now it's giving me this:

@ajkblue Does it never work or just sometimes?

[ajkblue]

It never works. All I can do is deauth from the network and then clicking on “Scan” causes the pop up “ A network scan could not be completed at this time.”

@ajkblue Try replacing the following:

_ = _open!(&airportHandle)
_ = _bind!(airportHandle, self.interfaceName)
let result = _scan!(airportHandle, &foundNets, scanParams)

with smth like:

var test = _open!(&airportHandle)
print(test)
test= _bind!(airportHandle, self.interfaceName)
print(test)
let result = _scan!(airportHandle, &foundNets, scanParams)

and check if they both print 0

[ajkblue]

Yup, they both return a 0:

@ajkblue Then what preferences did you change/enable?

[ajkblue]

I don't think I've changed anything? This is what my preferences window looks like:

Is there anything else I can try? I've cleared out my Xcode cache and re-cloned the repo and went thought all of the steps listed above again, verified that the Apple80211 file exists and I'm still getting the same error message. Even when changing the schemes in Xcode and launching as root. I also re-added the debug code which printed out 0 as shown below. I've verified that WiFi scanning and entering monitor mode works via Terminal. But I'm still getting the same error message in Xcode when launching the app, with or without running as root:

Now my JamWifi Preferences window looks like this:

Apple released a document that states WiFi scanning applications are not allowed on Mac OS. Does this interfere with this app? The file does not appear in my library, the private frameworks file.
