Anonymous users2024-02-06Bluetooth wireless technology is a low-cost, low-power, short-range RF wireless technology for mobile devices and WAN access points. At present, more than 2,000 companies support Bluetooth technology. This fact illustrates that Bluetooth is fast becoming one of the widely accepted low-cost wireless technologies for personal area networks (PANs).
Bluetooth technology enables short-distance signal transmission between broadband access devices, PCs, information appliances, and other devices.
When it was first introduced, Bluetooth technology was very slow, but as the technology evolves and more and more manufacturers in the fields of digital consumer electronics, mobile phones and automotive electronics produce Bluetooth-enabled products, it is bound to arouse more consumer interest in this technology and gradually understand the benefits of Bluetooth technology in the era of wireless communication.
Bluetooth technology is a short-range wireless connection technology used to replace cables or wires used in portable or stationary electronic devices. Its devices use globally available, license-free frequency bands for real-time data and voice transmission, with transmission rates up to 10Mbit s, supporting up to 3 voice channels and up to data transfer rates. That is to say, in the office, home and on the go, there is no need to lay special cables and connectors between any electronic devices, and a one-point to multi-point connection can be formed through the Bluetooth remote control device, that is, a "micro-grid" is formed around the device, and any Bluetooth transceiver in the network can communicate with the device.

Bluetooth"It is a strange name, an inconspicuous little thing, but it may play a leading role in the future development of information technology. With the development of information technology and digital technology, especially the growth of the need for the Internet and multi-communication, people's demand for communication is increasingly concentrated in the field of broadband network and wireless communication. "Bluetooth", a wireless communication technology for short distances proposed by Ericsson, Nokia, IBM, Intel and Toshiba, has become one of the hot spots in the industry.
Bluetooth is an open technical standard for short-range wireless communication. The wolf's teeth are jagged, but they bite together. Figuratively speaking, "Bluetooth" is a technology that can tightly bind unrelated electronic products such as headphones, laptops, refrigerators, and televisions.

As for A2DP, A2DP can allow two devices that also support Bluetooth audio transmission to connect to each other, whether it is a version or version, and can output audio such as CD quality (16
bits, khz).
If one of them does not support A2DP, the sound effect can only output HandsFreeProfile(8
bits，8
khz), even if the earphones are designed with dual earphones, they can only have a general **.
's mono sound quality, which is far from true stereo sound.
Applications of A2DP:
1 Bluetooth stereo headset.
Cell phone. 2 Bluetooth stereo headset + PC.
