Cant connect Lego Move Hub

[SvyatoslavNovikov]

Hi there.

Try connect Lego Move Hub to bricknill using boost_motor_position.py (Windows 10, Python 3.7, Asus BT400 dongle, bleak 0.10.0, bricknil 0.9.3)

When I start programm, i have next stactrace:

My Move Hub must connect automatically, or i must connect via windows bluetooth settings, or some other way?

Thanks.

Hi, looking at the release notes of bleak 0.10.0 (https://github.com/hbldh/bleak/releases), there is the information "Removed separate implementation of global discover method". Maybe this is related to your problem? You could try to downgrade your "bleak" version to 0.9.1. I am using bleak 0.6.1 and it works so far. If you will use something newer with success, please let me know.

Yes, i downgrade bleak to 0.9.1 version and have new stacktrace:

The above exception was the direct cause of the following exception:
