After installing the new Version of find3-cli-scanner on Raspbian I get the following error...

pi@raspberrypi:~ $ find3-cli-scanner -i mon0 -device scanner-pi3 -family test -server https://xxx.xxx.de -scantime 10 -bluetooth -passive -forever -no -modify 2018-07-24 10:58:22 [INFO] main.go func1:179 scanning bluetooth 2018-07-24 10:58:22 [INFO] main.go func1:185 working in passive mode 2018-07-24 10:58:22 [ERROR] bluetooth.go scanBluetooth:37 Failed to open device, err: %sno supported devices available

You should be using sudo ....

Also, what version of Raspberry Pi do you have? Are you sure it has bluetooth?

kappelloss commented 6 years ago

I have tried with using "sudo" without any luck... I am using the Pi Zero W and my workaround was to skip back to Commit d0af2e3, which now works perfectly...

schollz commented 6 years ago

Can you describe more about what didn't work and why it does work?

I have a Raspberry Pi 3 with the brand new raspbian and the latest version (d7edff42e6bbe15c06a3cdb30fdbb3fc9d4f3ea7) works great:

$ sudo ./find3-cli-scanner -f z -d z --server localhost -debug -bluetooth -s 5

I just installed the newest Raspbian on a Raspberry Pi Zero W and executed the following commands before I followed your install tutorial:

  1. sudo rpi-update
  2. sudo apt-get update
  3. sudo apt-get upgrade

By the way there is another strange thing that I noticed... When I am adding the -bluetooth flag than the scanner only scans for bluetooth and not any longer for wifi... So I rolled back to 300e659 and everything works like a charm now...

Maybe I have to say that I am using the nexmon driver for passiv wifi scanning instead of an extra wifi card...

So did the bluetooth work with the newest raspbian?

When I am adding the -bluetooth flag than the scanner only scans for bluetooth and not any longer for wifi...

This is a new feature, not a bug. To scan for wifi+bluetooth you should do -wifi -bluetooth. To scan just one or the other, you just use one of the flags.

kappelloss commented 6 years ago

No the bluetooth does not work with the newst raspbian... Sorry man that I tought it is an bug (doesn't know that I have to add the -wifi flag), but I am happy that you added this feature (some days ago I asked you for this...) :D

@kappelloss I'm sorry I have to ask this, but are you at all associated with https://github.com/Thomas499 ? If not, may I know what you are using FIND3 for, and can you also let me know if you are part of a company that is using FIND3?

I've had issues with several users (see https://github.com/schollz/find3/issues/93 and https://github.com/schollz/find3/issues/66#issuecomment-382998197) who create accounts just for the purpose of create issues and having me solve them. It turns out these particular users were working in a company. They were not interested in contributing to open-source, but only interested in extracting free support and free bug fixes.

Your account looks very similar to theirs - you joined in late April and have almost entirely been posting issues on FIND3. This has raised red flags for me and I can't continue to work on your issues until I've figured out your relationship to FIND, sorry.

For the record, I am happy to add new features and bug fixes for companies, but I have to do it through consulting. I have a good rate and I can do things much faster through consulting, if interested, email me at zack.scholl@gmail.com.

Okay, closing this because its not a reproducible bug and user might be unresponsive.
