On April 8, 2021, AGC held a seminar on the new generation of Bluetooth technology LE Audio at St.Helen Shenzhen Bauhinia Hotel in Futian District, Shenzhen. This seminar is the first authoritative seminar organized by a domestic third-party certification institution. It is mainly concerning the interpretation of the published LE Audio technical specifications. The seminar attracted a large number of entrepreneurs, elite and experts from Bluetooth related industry. The lecturer is Totti Huang--Bluetooth Qualification Consultant accepted Bluetooth SIG.
At CES in early 2020, Bluetooth SIG formally introduced the next generation of Bluetooth Audio technology - LE Audio to the industry. In the context of the global epidemic outbreak in 2020 and the difficult transnational communication, through the unremitting efforts of the relevant working groups of Bluetooth SIG and the careful organization of Bluetooth SIG, a series of technical specifications related to LE Audio have been successively released in 2020 as planned, which demonstrates the spirit of unity and cooperation among Bluetooth SIG members to overcome difficulties together.
