It is different hardware, different architecture, different specification, and hence different target applications. BLE is not compatible with the Bluetooth Classic. BLE is a massive divergence from the Bluetooth Classic. The second type is Bluetooth Low Energy (BLE), which emerged along with the Bluetooth specification 4.0 in 2010. You typically can not efficiently operate a Bluetooth Classic device on a coin cell battery. This type of Bluetooth has no regard to power consumption. This type of Bluetooth is still used in our cars, Bluetooth-enabled headsets, speakers and smart printers to transfer files. The Bluetooth Classic is intended for short-range communication with a relatively higher throughput than BLE. The first type is the Classic, which could be Bluetooth Basic Rate (BR), Enhanced Data Rate(EDR) or the High Speed (HS). When people talk about Bluetooth nowadays, there are two main types.
Bluetooth Protocol Timeline (Major releases outlined) As can be seen from the figure below, prior to 2010, there was only one main type of Bluetooth, after 2010 we have BLE and Bluetooth Classic.
The figure below shows the timeline of BLE and Bluetooth Classic, highlighting its major releases and main features introduced in each release. It is a wireless communication standard for short range, ultra-low-power personal area network operated in the unlicensed 2.4 GHz ISM band. Bluetooth Low Energy, which was initially advertised as “Bluetooth Smart”, is a light-weight independent branch of the original “now known as Classic Bluetooth ” and was introduced as part of the Bluetooth 4.0 core specification in 2010. Bluetooth Low Energy vs Bluetooth Classicīefore we examine the BLE architecture, we will first compare it to Bluetooth Classic. In the exercise section of this lesson, you will be introduced to the general structure of a connection-orinted BLE firmware, and the minimum nRF5 SDK modules needed to make a BLE device discoverable and connectable. Gaining fundamental knowledge about the BLE architecture will pay off, and will significantly help when we reach Lesson 4, and start diving into Nordic Semiconductor BLE Protocol Stack (SoftDevice) API. We will also understand the main differences between Bluetooth Low Energy and Bluetooth Classic. The key information needed to get started with BLE on an nRF5x chip is provided per each layer of the architecture. In this lesson we will take a look at the Bluetooth Low Energy (BLE) protocol, its versions and architecture.
