Bluetooth technology four areas of application solutions
today to share on the application of bluetooth technology solutions, bluetooth technologyFour Solution Areasmeans.audio transmission, data transmission, device network, location services.
1. Bluetooth audio transmission scheme
one-to-one connection: In the Bluetooth 2.0 era, a master device (such as mobile phones, cars, etc.) central control, connected to a slave device (such as Bluetooth speakers, Bluetooth headsets, etc.), Bluetooth speakers have become the most popular applications;
TWS Headphones: The epoch-making TWS true wireless Bluetooth headset application realizes the "true wireless" of the separation of left and right channels. It has shined in the past four or five years and will continue to develop at a high speed;
LE Audio: LE Audio, announced last year, takes Bluetooth audio technology to another level. It can better support one-to-many audio transmission and provide higher quality and lower latency audio encoding.
2. Bluetooth data transmission scheme
IoT era for data transmission: Before cellular networks and wireless local area networks became popular on a large scale, Bluetooth technology was often used for file sharing across devices; now, data traffic is no longer a problem;
Internet of Things era gave birth to low-power Bluetooth protocol: The demand for low power consumption of data transmission function of Internet of Things devices has given birth to the birth and popularity of low power consumption Bluetooth protocol; Bluetooth Technology Alliance has been continuously upgraded after the launch of version 5.0 in Bluetooth, optimizing transmission rate, transmission distance, broadcast data transmission, power control, etc.
3. Bluetooth device network scheme-Bluetooth mesh
IoT Advantages:Bluetooth mesh expands the original point-to-point star network to a mesh network, which can better meet the needs of Internet of Things devices;
Power Advantages: Based on low-power Bluetooth technology, Bluetooth mesh can be used in power-sensitive devices;
Scene Advantage: At the same time, the Bluetooth can expand the data transmission range for scenarios that require data relay, which is very suitable for applications in smart light control, whole-house smart control and other scenarios.
4. Bluetooth location service scheme
Bluetooth Location Service Based on RSSI Technology:The triangulation method based on RSSI data has been applied to Bluetooth positioning scheme for a long time. It can be used to set up Bluetooth beacon for indoor navigation in the scene of Shangchao, and can also be used to design Internet of Things products such as anti-lost devices, but usually only achieve sub-meter accuracy.
Bluetooth 5.1:Bluetooth 5.1 increases the support for AOA and AOD at the protocol level, and the accuracy reaches decimeter or even centimeter level, which can be widely used in indoor positioning, asset tracking and other fields.
The above is the introduction of the four solutions of Bluetooth technology to share, I hope to help you.
