BLE service for Magic Light BLE RGB bulbs

Project description

Introduction

Documentation Status Discord Build Status Code Style: Black

BLE service for Magic Light BLE RGB bulbs. Available from Amazon here.

Dependencies

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-ble-magic-light

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-ble-magic-light

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ble-magic-light

Usage Example

"""This demo connects to a magic light and has it do a colorwheel."""
import adafruit_ble
import _bleio

from adafruit_ble.advertising.standard import ProvideServicesAdvertisement
from adafruit_ble_magic_light import MagicLightService

# CircuitPython <6 uses its own ConnectionError type. So, is it if available. Otherwise,
# the built in ConnectionError is used.
connection_error = ConnectionError
if hasattr(_bleio, "ConnectionError"):
    connection_error = _bleio.ConnectionError

def find_connection():
    for connection in radio.connections:
        if MagicLightService not in connection:
            continue
        return connection, connection[MagicLightService]
    return None, None

# Start advertising before messing with the display so that we can connect immediately.
radio = adafruit_ble.BLERadio()

active_connection, pixels = find_connection()
current_notification = None
app_icon_file = None
while True:
    if not active_connection:
        print("Scanning for Magic Light")
        for scan in radio.start_scan(ProvideServicesAdvertisement):
            if MagicLightService in scan.services:
                active_connection = radio.connect(scan)
                try:
                    pixels = active_connection[MagicLightService]
                except connection_error:
                    print("disconnected")
                    continue
                break
        radio.stop_scan()

    i = 0
    while active_connection.connected:
        pixels[0] = colorwheel(i % 256)
        i += 1

    active_connection = None
