Dalian Daquanding Group launched a smart lighting + audio integrated solution based on CSR Bluetooth technology

On September 16, 2015, the leading semiconductor components distributor in the Asia-Pacific market, Dalian General Holdings, announced that its subsidiary Quanding launched a smart lighting and audio integrated solution based on CSR Bluetooth technology. In this solution, the CSR Bluetooth® Smart solution – CSR Mesh is used as the system networking technology, and then connected to the Bluetooth lighting + audio integrated machine based on CSR TWS (True Wireless), which can realize smart phone APP, A variety of control methods such as touch sensing and buttons.

In a modern home environment, light and music are integral to creating a comfortable environment. This time, Dalian Daquanding organically combines the two to launch this cross-border intelligent solution: providing adjustable multi-color and multi-level brightness lighting; music is rich in low frequency, clear and transparent in mid and high frequency, and balanced and full in three frequencies ; In addition to having functions such as hands-free calling and timing alarms, it will continue to expand through its applications.

In order to achieve low power consumption and high stability of the system, Dalian University Quanding 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, which transmit the received signal back. Signals can be transmitted individually to a single device or to multiple devices simultaneously, or even to different devices belonging to multiple groups. Its control functions are available via standard Bluetooth Smart-equipped home appliances such as light 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 using an access device like a router to ensure an excellent user experience.

True Wireless is based on CSR’s popular BlueCore5-multimedia platform and can be used in devices including stereo headphones and speakers to work with any A2DP device currently on the market. This solution of Dalian Daquanding is developed based on the TWS Bluetooth 4.0 version. Connect the main speaker through the mobile phone, and then connect the slave speaker wirelessly through Bluetooth to achieve true Bluetooth left and right channel wireless separation. When the slave speakers are not connected, the master speakers return to a single stereo. No lag, good sound quality. CSRA64215 integrates ultra-low-power DSP, application processor, high-performance stereo decoding, power management subsystem and LED driver. It is a single-chip Bluetooth audio ROM solution, which is used in the design of high-end, high-quality Bluetooth stereo products. Development platform .
