Misfit Bolt Javascript Interface

Implementation of sandeepmistry/noble-device, that helps driving a Misfit Bolt LED bluetooth bulbs.

Largely inspired by fayep's Python implementation, and sandeepmistry's YeeLight Bluetooth implementation.

Based on Yeelight Blue Message Interface specifications.

Features

• Control of color via RGBA and HSB schemes.
• Control of state, with in-bulb persistence of last color set, and in-app persistence of last brightness set.
• Control of gradual effect transition (progressive or immediate).
• Control of the bluetooth name of the bulb.

Prerequisites

To connect to the Misfit Bolt, you need BLE capabilities. See sandeepmistry/noble prerequisites for more details.
