Quanding Group, a subsidiary of the General Assembly, launched an integrated solution of intelligent lighting and audio based on CSR Bluetooth technology. In this solution, Da Lian Da Quan Ding uses the CSR Bluetooth Smart solution-CSR Mesh as the system networking technology, and then connects to the CSR TWS (True Wireless)-based Bluetooth lighting + audio integrated machine, which can realize smart phone APP, touch Various control methods such as shooting sensor and button.

In the modern home environment, light and music are indispensable factors for creating a comfortable environment. This time, Da Lian Da Quan Ding organically combined the two to launch this cross-border intelligent solution: providing adjustable multiple colors, multi-level brightness lighting; strong low frequency music, clear and transparent middle and high frequencies, and balanced three-frequency ; In addition to functions such as hands-free calls and timed alarms, it will continue to expand through its applications.

In order to realize the low power consumption and high stability of the system, Da Lian Da Quan Ding specially selected CSR's Bluetooth Mesh and TWS technologies and products:
The CSR Mesh protocol uses Bluetooth Smart technology to transmit signals to other networked Bluetooth Smart devices, and these Bluetooth Smart devices then transmit the received signals back. The signal can be transmitted to a single device alone or to multiple devices at the same time, or even to different devices belonging to multiple groups. Its control function can be realized by household appliances equipped with standard Bluetooth Smart, such as lighting switches or most smartphones or tablets on the market. For application in the smart home environment, CSR has pre-integrated the Bluetooth configuration and control protocol into the CSR1010 chip, and performs complex installation, pairing or use of access devices like routers to ensure an excellent user experience.
True Wireless is based on CSR's popular BlueCore5-multimedia platform, which can be used in devices including stereo headsets and speakers, and can collaborate with any A2DP devices currently on the market. The solution developed by Da Lian Quan Ding is based on TWS Bluetooth 4.0 version. The main speaker is connected through the mobile phone, and then the slave main speaker is connected to the slave speaker via Bluetooth wirelessly to achieve true wireless separation of the left and right channels of Bluetooth. When the slave speaker is not connected, the master speaker returns to a single stereo. No delay, good sound quality. CSRA64215 integrates ultra-low power consumption DSP, application processor, high-performance stereo decoding, power management subsystem and LED driver. It is a single-chip Bluetooth audio ROM solution, which is applied to the development platform for the design of high-end, high-quality Bluetooth stereo products .
