Applications based on Bluetooth Low Energy technology are primarily intended to be used for places where energy management is supreme concern. The wise use of this modern technology is becoming more common in the sensor based applications.
Bluetooth LE has been designed to accommodate portable devices in a star network. Nodes can dynamically connect with and drop off the network as they move into or out of range. Bluetooth LE uses asynchronous protocol, allowing both master and slave to wake up simultaneously. This sleep and wake up process takes place periodically as directed by the application to pass data to the host. Since both (Master and Slave) can be powered down most of the time, this makes bluetooth LE devices to consume less energy. Nodes in low-power sensor networks might only go into active mode when to pass a short data, leading to a long battery life.
It is also a leading candidate for ultra-low power wireless sensor networks, such as those used to monitor vibrations on aircraft wings and industrial motors as well as cracks in bridges and buildings. According to analysts at Research and Markets, “Bluetooth Low Energy will be a significant contributor to the overall Wireless Sensor Network market, representing nearly half of all shipments in 2015.”

What do you mean by short data ?

Short data means data in small chunks unlike audio and video which is continuous..

And how it would have worked with synchronous protocol? Thanx |
