The non-connectable beacon is a Bluetooth low energy device in broadcasting mode. It simply transmits information that is stored internally. Because the non-connectable broadcasting does not activate any receiving capabilities, it achieves the lowest possible power consumption by simply waking up, transmit data and going back to sleep. This comes with the drawback of dynamic data being restricted to what is only known to the device, or data being available through external input from example serial protocols (universal asynchronous receiver/transmitter (UART), serial peripheral interface (SPI), universal serial bus (USB), and so forth).
