WSL/Cygwin: Bluepy won't install, sudo: ble-scan: command not found #15

Closed JBrakefield closed 3 years ago

JBrakefield commented 3 years ago

I've tried everything to get this running on my Ubuntu (20.04) WSL (I also tried getting it to run in Cygwin with no luck). I had a lot of trouble installing that bluepy library specifically, and when I get to the step "Find bluepy-helper" it is simply not there. My ~/.local/lib/python3.8/site-packages has no folder at all for bluepy, even after it finally installed with no errors.

I tried testing ble-scan anyway, but it says the command is not found when using sudo.

Did you run pip install as normal user or root? It might be in the system site packages instead, so /usr/lib/python3.8/site-packages. You can check the paths with python -m site. Also I would recommend python virtualenv to get a isolated environment.

That being said, even after fixing that it will most likely not work, because WSL does not support direct hardware access or bluetooth in general: https://github.com/microsoft/WSL/issues/242 Please try it with a native Linux installation or live CD/USB stick. Windows is currently not supported, this might change in the future after the migration to another bluetooth backend is done (ble-serial version 2.0+).

Thanks for the response. You are probably correct that I can't use this on my Windows machine yet. I'm also trying to learn Bleak in hopes that library works for me.

I am closing this as WSL is not supported, but I am migrating to Bleak in #17 and just merged Windows support #18 in. Checkout the bleak-backend branch and please let me know if this works for you. It requires native python 3.8 and com0com. Data is read/written to \\\\.\\BLE. You can use the included ble-setup script to correctly create a BLE<>COM9 port pair.
