METHOD FOR BIDIRECTIONAL TRANSMITTING AND RECEIVING DATA IN WIRELESS USB SYSTEM

摘要

A method for bidirectional data transmission and reception in a wireless USB system is provided to enable bidirectional data transmission and reception in a wireless USB device of a wireless USB system where a wireless USB(Universal Serial Bus) DRD(Dual Role Device) is not realized by enabling the wireless USB system to not only confirm a data transmission request at a host but also output a receiving command. A host(10) confirms periodically whether or not a file to be transmitted in a file list is selected in a device(20)(S54). A file to be transmitted from the device to the host is selected(S53), and the device informs through a response that the transmission files are selected(S55). The host request to the device the files to be transmitted in the selected transmission files(S56). The device transmits the selected files to the host(S57), and the host updates a file list after storing the files(S58).
