Dalian Daquanding Group launched a low-power Bluetooth audio (LE Audio) answer based mostly on Qualcomm merchandise

“The Bluetooth Particular Curiosity Group (SIG) has introduced a brand new Bluetooth core specification, CoreSpec 5.2, most notably with the promulgation of the next-generation Bluetooth audio, LE Audio. LE Audio not solely helps stereo in linked state and broadcast state, but additionally enhances Bluetooth audio efficiency by a collection of specification changes, together with lowering latency and enhancing sound high quality by LC3 codec.

“

On March 10, 2022, Dalian Basic Holdings, a number one semiconductor element distributor devoted to the Asia-Pacific market, introduced that its subsidiary Quanding launched a low-power Bluetooth audio (LE Audio) based mostly on Qualcomm’s QCC3056 chip. plan.

On January 6, 2020, the Bluetooth Particular Curiosity Group (SIG) introduced the brand new Bluetooth core specification CoreSpec 5.2, probably the most notable of which is the promulgation of the next-generation Bluetooth audio LE Audio. LE Audio not solely helps stereo in linked state and broadcast state, but additionally enhances Bluetooth audio efficiency by a collection of specification changes, together with lowering latency and enhancing sound high quality by LC3 codec. After realizing the short-distance interconnection of all issues by LE, with the assistance of LE Audio, Bluetooth shall be utterly reborn and take off within the period of the Web of Issues. The low-power Bluetooth audio (LE Audio) answer based mostly on the Qualcomm QCC3056 chip by Dalian Daquan Ding integrates the capabilities required for the following era of Bluetooth merchandise, helps the Bluetooth 5.2 customary, and has the traits of low energy consumption and low latency.
