摘要： This application discloses a packet loss data error correction method and apparatus in dual-transmit mode, a device, and a system. The method includes: step S100: driving a first Bluetooth playing device to establish an information exchange link with a second Bluetooth playing device; step S200: controlling the first Bluetooth playing device to exchange link information with the second Bluetooth playing device; step S300: controlling the first Bluetooth playing device to receive first current audio data that is sent to the first Bluetooth playing device by an audio source device; step S400: sending a first forwarding request to the second Bluetooth playing device a preset time interval after a local link subevent anchor; and step S500: receiving the first current audio data that is forwarded by the second Bluetooth playing device. It can improve communication quality of dual Bluetooth playing devices.

摘要： A method, circuit, audio playback device, and system of sending and receiving Bluetooth packet loss data is disclosed. The method includes: step S100, receiving a forwarding request sent by a second audio playback device in a receiving state; step S200, monitoring the retransmission information of an audio source device retransmitting current audio data on Link 1 according to the forwarding request; step S300, determining whether the retransmission information is monitored; step S400, switching from the receiving state to a sending state; and step S500, forwarding the current audio data to the second audio playback device through Link 2 in accordance with the time sequence of the audio source device retransmitting the current audio data. The signal can be provided to the second audio playback device from different locations.
