LED BLE Library

The ble_led (About Modules) library turns your Espruino device into a Bluetooth LED device compatible with the Python led-ble library which means your device can appear in Home Assistant with the LED BLE integration.

Once configured, a device running this library will appear in http://homeassistant/config/integrations/dashboard where it can be used alongside all your other devices.

Usage

Simply instantiate as follows:

require("ble_led").setup(function(state) {
  if (state.on) {
    // state.r/g/b arr in the range 0..255
    LED1.pwm(state.r/256);
    LED2.pwm(state.g/256);
    LED3.pwm(state.b/256);
  } else {
    digitalWrite([LED1,LED2,LED3],0);
  }
});

Every time the light state changes, the callback will be called with an updated state variable, which is of the form:

{
  on:false,
  r:255,
  g:255,
  b:255,
  w:255,
  version:0
}

In the example above, we assume your device has red, green and blue LEDs as LED1/2/3, but you could wire up external LEDs, or use the state.on value to trigger something other than a light.
