Bluetooth Low Energy in a connectionless model
Bluetooth Low Energy in a connectionless model best bluetooth earphones for running
The original intention of designing classic Bluetooth is to replace wired media such as headphone cables, mouse cables, and file transfer cables. This means that the cost of establishing the link is less important because the connection will be maintained for minutes, hours, or even days; the delay of seconds at the start of the connection is also unimportant. However, Bluetooth Low Energy changed all that. www.bjbjaudio.com
The basic idea of low power consumption is that the connection is transient. When you need to do something or check a situation, you can quickly create a connection, do what you need to do, and then disconnect. If a device advertises status information every five minutes. The total time the radio is on during the day will not exceed 1s. This means that the radio is off 99,999% of the time - 100% of the time if only 4 significant digits remain. Any delay in establishing each connection will significantly increase power consumption. www.bjbjaudio.com
Bluetooth Low Energy can establish a connection, send data, and disconnect gracefully in about 3ms. This is a boon for many devices that contain state information but have been unable to afford the energy costs of wireless communication, and now consider adding Bluetooth low energy. Even simple gadgets as small as a button can use this technology, and with scavenged power, they can even work without batteries. www.bjbjaudio.com

The most successful technologies are often designed around different paradigms, and Bluetooth Low Energy is no exception. Bluetooth low energy technology uses two main architectural paradigms: client-server architecture and service-oriented architecture. www.bjbjaudio.com
client-server architecture
In a client-server architecture, a client sends a request to a server over the network, and the server replies with a response. This is the main paradigm behind the internet. Undoubtedly the most successful web technology ever released. For example, when you type a URL address in a web browser, it first sends the address to a DNS server. The DNS server returns the corresponding IP address that has been assigned to the name. The client then sends a request to the server via the Hypertext Transfer Protocol (HTTP), and once the connection is established, requests the server to send the requested resource. The server then replies with the appropriate resource, usually a text file containing markup information (HTML) that tells the browser how to display the information. The file can also contain some URLs for clients to get resources, such as pictures or other pages. These extra links are seen as the real reason why HTML pages are linked to each other into a huge web network, and it is because of this that the term web pages and web servers comes into existence. www.bjbjaudio.com
