Kind Code:

A1

Abstract:

The present application relates to the field of short-distance communications. Disclosed are a point to multi-point data transmission method and device, using Bluetooth to implement data transmission between one mobile phone and left and right earplugs of TWS earphones, respectively, and implementing play-level synchronization of audio data between left and right earplugs of the TWS earphones. The left earplug and the right earplug of the TWS earphones are respectively paired with an electronic device to negotiate service content, and a service type supported by the electronic device, left earplug, and right earplug comprises a BLE-based audio profile; the left earplug receives left configuration information sent by the electronic device for configuring a left ISO channel, and the right earplug receives right configuration information sent by the electronic device for configuring a right ISO channel; the left earplug receives audio data sent by the electronic device by means of the left ISO channel according to the BLE-based audio profile, and the right earplug receives audio data sent by the electronic device by means of the right ISO channel according to the BLE-based audio profile; and the left earplug and the right earplug play the respective received audio data according to a left timestamp.
