[graphics tutorial] Changhong TV how to connect Bluetooth devices?
Some time ago, a Bluetooth handle launched by Xiaomi has led many users to turn their attention to connectable Bluetooth devices. Since the network is stable and fast, Bluetooth transmission is widely used not only for wireless remote control but also for data transmission. Among them, the use of smart TVs is also varied. So how do ordinary smart TVs make Bluetooth connections? The following small series will be introduced in detail for everyone.
1. What is Bluetooth? Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and personal area networks of buildings (UHF radio waves in the ISM band of 2.4 to 2.485 GHz). Bluetooth can connect multiple devices, overcoming data synchronization problems.
Second, the Bluetooth standard
There are currently 8 standard versions of Bluetooth, namely V1.1/1.2/2.0/2.1/3.0/4.0/4.1/4.2. Among them, the V1.1/1.2 version is an early technology and it has basically been eliminated. The most widely used is the V2.0/2.1 version, the transmission rate can reach 2M/s or more, and can simultaneously transmit data and voice. Versions V3.0 and V4.0 are improved versions, and the transmission speed and distance have been greatly improved. The theoretical maximum speed of transmission has reached 24Mbps, especially Bluetooth 3.0 high-speed technology and Bluetooth 4.0 BLE low-power technology. The Bluetooth version is naturally the higher the better, taking into account the transmission distance and power consumption issues, the latest Bluetooth 4.1 is the preferred, but the current market, Bluetooth 4.1 products are not many, while the mainstream Bluetooth 4.0 product cost-effective, as Bluetooth 3.0, 2.1 and below have lost the value of purchase.
Third, the role of Bluetooth Bluetooth is usually a pair or pair of pairs to use. You can connect between two Bluetooth devices. You can connect bluetooth devices (including audio, headphones, cameras, joysticks, mouse and keyboards, etc...) to a Bluetooth-enabled TV.
Fourth, on the TV Bluetooth adapter and Bluetooth headset (sound) matching method
Specific connection matching steps:
1. Directly connect the 3.5mm audio cable (Figure 7) to the 3.5mm audio port of the TV (if the TV does not have a 3.5mm audio output, you can use a 2.5mm Lotus head to 3.5mm female audio cable (Figure 8) to connect the TV The left and right channel outputs and the 3.5mm audio cable connect the TV and the Bluetooth adapter.
2. Press and hold the function key of the Bluetooth adapter for 5~8 seconds, and turn on the Bluetooth headset (audio) at the same time. The Bluetooth adapter will automatically search for and connect the Bluetooth headset (audio) within the valid range.
When searching for pairings: The blue and red lights (figure 3, legend 4) flash alternately.
When the search is successful: the blue light (figure 5, legend 6) flashes normally (the light color described here is just an example, which corresponds to the light color of the real object).
Five, Bluetooth handle connection method (illustration)
The method described in the above illustration is common for most products. If users purchase different types and brands of Bluetooth handles, please carefully read the instructions of their purchased product to perform connection and pairing.
6. Conclusion Bluetooth has many advantages such as perfect encryption, stable transmission process, and rich compatible devices. From the 1.1 version to the 4.2 version, there is a difficult process. The Bluetooth Bluetooth 2.1+ EDR standard and the 4.0 standard are the most common and the most widely used ones. Bluetooth technology is closely related to our life, work, driving, entertainment, and multimedia. By using Bluetooth technology products, people can eliminate the worries of the home office cable winding, conduct hands-free conference calls by connecting a mobile phone to speakers, and listen via wireless stereo headphones. Streaming music delivered by home audio or other similar audio devices.
Each generation of Bluetooth standard upgrades is believed to be full of attractiveness for electronic products such as tablet phones. Products with a higher Bluetooth standard will improve overall performance, such as wider range of matching, higher transmission speed, more energy saving, and direct access to the Internet. In addition, it is believed that the application of Bluetooth in the future will be more extensive and more user-friendly. However, the release of the Bluetooth 4.2 standard is still a minor version update and does not bring a turning point, or a point of change. If there is still no reform, it will most likely be replaced by NFC, which is gaining momentum.
