Python library to interact with LEGO Move Hub

Requires gattlib to be installed, currently Python 2.7 only

Best way to start is to look into demo.py file, and run it.

Features

• auto-detect and connect for Bluetooth device
• auto-detects devices connected to Hub
• permanent Bluetooth connection server for faster debugging
• angled and timed movement for motors
• LED color change
• sensor data subscribe/unsubscribe
• battery voltage available

Usage

from pylgbst import MoveHub

hub = MoveHub()

for device in hub.devices:
    print(device)

Debug Server

sudo python -c "from pylgbst.comms import *; import logging; logging.basicConfig(level=logging.DEBUG); DebugServer(BLEConnection().connect()).start()"

Roadmap

• make notifications from pygattlib to quickly get into parallel thread, to avoid segfaults
• support working with push button
• Give nice documentation examples, don't forget to mention logging
• make angled motors to be synchronous by default => 3-state status
• make sure unit tests cover all important code
• generalize getting device info + give constants (low priority)
