Abstract
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.
