Run fails with cannot import name 'IOBluetoothDeviceInquiry'

[artemptushkin]

Hey! Could you assist please with installation, I keep getting these. Tried to reinstall everything I knew.

I'm from Java and quite newbie with python env

ego-hub-tk git:(main) ✗ python3 run_command.py

Lego-hub-tk (as per docs) should be located somewhere like this: C:\Users\artemptushki\AppData\Local\lego-hub-tk
Did you run command pip3 install -r requirements.txt inside lego-hub-tk?

@Nurech yes I did, well for me (macbook) it's located not in AppData. I'm wondering, maybe MacBook env affects this as when I go through the trace I see there if on OS, so it might be on Windows. But I think this is a question of the library then pip3 install pybluez I installed this, but still have issue

Hello and thanks for reporting this. I don't use mac, but @ws1088 has tested on mac -- maybe could offer some insight?

Disclaimer aside, since the error occurs on "import bluetooth" it looks like there's something amiss with the bluetooth python packages. I don't have any advice other than consult mac users of python bluetooth. Sorry.

pybluez dependency is likely the issue I haven't tried on osx but also causes issues for raspberry as well I think

macosx issues on pybluez github

[SpudGunMan]

Mac issue is changes in the way that UUID and SerialUSB was working osx12.3 aims to fix them however the packages will need to be updated to facilitate this, pybluez project might be slower on the shift. https://github.com/Jakeler/ble-serial is an attractive project inline with this issue worth looking at

I actually have code removing the need for pybluez in the core bluetooth communications code. I will get that committed soon. The only thing I couldn't work out how to do is detect the device -- which is only of value if you want the "usb/bt multiplexing".
