LED

The MetaWear board comes with a builtin RGB LED, encapsulated with the MBLLED object.

Set Color

This snippet will set the LED to a solid red color.

device.led?.setLEDColorAsync(.red, withIntensity: 1.0)

Flash Color

This snippet will flash the LED a red color indefinitely.

device.led?.flashColorAsync(.red, withIntensity: 1.0)

Or you might find it beneficial to flash only a few times.

device.led?.flashColorAsync(.red, withIntensity: 1.0, numberOfFlashes: 3)

Turning Off

This snippet will completely shut down the LED.

device.led?.setLEDOnAsync(false, withOptions: 1)
