A wireless audio monitoring method and a wireless audio system. The wireless audio monitoring method includes: establishing a first communication link between a primary audio device and a sound source device, so that the primary audio device acquires characteristic parameters of the sound source device; using, by the primary audio device, the characteristic parameters of the sound source device to masquerade as the sound source device and become a pseudo sound source device; establishing a second communication link between the pseudo sound source device and a secondary audio device, so that the secondary audio device acquires communication parameters of the first communication link; and monitoring, by the secondary audio device, the first communication link according to the communication parameters of the first communication link. The secondary audio device can acquire part of information in the communication parameters of the first communication link when the second communication link is established.

Wireless audio monitoring method and wireless audio system

A wireless data transmission method includes sending by an external device a data packet; receiving by a primary device and a secondary device the data packet sent by the external device. When the secondary device does not receive the data packet sent by the external device correctly, sending by the secondary device a feedback signal to the primary device. When the secondary device receives the data packet sent by the external device correctly, not sending the feedback signal. The method further includes detecting by the primary device if the secondary device has sent the feedback signal. When the primary device receives the data packet successfully and detects that the secondary device has not sent the feedback signal, sending by the primary device an ACK signal to the external device; otherwise, sending by the primary device a NACK signal to the external device.
