Transferring data over Bluetooth using intermediary bridge

摘要

In one or more embodiments, a first device such as a mobile phone can establish a wireless connection with second device, and the second device can act as a bridge between the first device and a peripheral device, such as a printer, so that the first device need not establish a secure pairing or other type of direct connection with the peripheral device. The second device provides a profile of the peripheral to the first device. The first device can then use the profile to access the peripheral device via the second device, with the second device passing data between the first device and the peripheral identified by the profile. This bridging feature simplifies the process of using the peripheral devices, since no secure pairing or other configuration procedure is needed to enable the first device to access the peripheral.

主权项

1. A method for transferring data from a first device to a second device via an intermediary device, the method comprising:
at the intermediary device: coupling the intermediary device to the second device via a first connection; receiving profile information from the second device via the first connection, the profile information describing one or more capabilities of the second device; storing, in a table of associations between devices and profiles in a memory of the intermediary device:
an association between the second device and the profile information received from the second device, andan indication that the association represents a remote device profile; coupling the intermediary device to the first device via a second connection; forwarding the profile information to the first device via the second connection; and transferring the data from the first device through the intermediary device to the second device via the first and second connections.
