Recently, using for communication purpose data sharing as like in through phones, cameras, televisions, speakers and headphones. today’s needful thing is data sharing through wires and wirelessly. In wireless device most using device is Bluetooth. Bluetooth is a wireless technology standard of course the two are related, but the wireless connection between your phone and the earpiece is called Bluetooth… not the piece itself. Bluetooth is developed as a way to exchange data over a short range without the need for wires. and another option to Bluetooth is Bluetooth Low Energy (BLE). Bluetooth low energy another wireless device is used low power variation to transfer data.Bluetooth and BLE(Bluetooth Low Energy) are Wireless Personal Area Network(WPAN) standards.

Let’s see detailed in Bluetooth and Bluetooth low enable (BLE)…….

Bluetooth — It is a wireless technology around us in all the smart devices. As we know using Bluetooth we can transfer text files, photos, videos and more between mobile phones and other smart electronic devices. It operates in 2.4 GHz band and it forms PAN (Personal Area Network) for communication.

Bluetooth is a Connection Oriented technology, connection need to be established first between Bluetooth compliant devices before data transfer takes place.

Bluetooth is a wireless technology that uses low-energy radio waves to send wireless data between Bluetooth-enabled devices. It’s similar to Wi-Fi in that it operates over radio waves. However, Bluetooth can work between any two enabled devices and does not require additional network equipment such as routers or modems, making it a popular choice for sending data between mobile electronics over close ranges. Bluetooth works over a maximum distance of 164 feet between devices, but that range is more than enough for many home,car,health and consumer electronics applications.

Bluetooth Low Energy(BLE) — Bluetooth version 4.0 is known as Bluetooth Low Energy or BLE. It is also referred by other names such as Bluetooth smart or Wibree. It is low power variation of original traditional Bluetooth standard. Like Bluetooth, it is also managed and maintained by Bluetooth SIG. Due to low power consumption and low power sleep modes.

It operates in the same band as standard Bluetooth but uses different FHSS scheme. As BLE devices are incompatible with standard Bluetooth devices, they will not inter-operate with them. Just like Bluetooth, BLE operates in the 2.4 GHz ISM band. Unlike classic Bluetooth, however, BLE remains in sleep mode constantly except for when a connection is initiated. The actual connection times are only a few ms, unlike Bluetooth which would take ~100ms. The reason the connections are so short, is that the data rates are so high at 1 Mb/s.

Bluetooth VS. Bluetooth Low Energy Difference — Bluetooth and Bluetooth Low Energy are used for very different purposes. Bluetooth can handle a lot of data, but consumes battery life quickly and costs a lot more. BLE is used for applications that do not need to exchange large amounts of data, and can therefore run on battery power for years at a cheaper cost. It all depends on what you’re trying to accomplish.

Bluetooth and BLE(Bluetooth Low Energy) are Wireless Personal Area Network(WPAN) standards. Bluetooth Low Energy is developed to take care of sending small chunks of data. It’s designed to run Internet of Things(IoT) devices using coin cells. Network/Topology used in Bluetooth is scatternet and in BLE used Star Bus.

As we know Bluetooth is used for network requiring data exchange as well as wireless headset and other consumer devices. BLE is used for applications such as mobile payment, healthcare, ticketing or access control. Both technology based devices are low cost. Both Bluetooth and BLE networks consist of master and slave devices. Nodes/Active Slaves in Bluetooth is 7 and in Bluetooth Low Enable is Unlimited.
