Abstract

The disclosure describes techniques for the isochronous transfer of data between a central device and one or more peripheral devices. For example, the central device may comprise any type of electronic device that is able to distribute data to peripheral devices using a wireless protocol. The isochronous transfer of data from the central device may provide an efficient method for wirelessly delivering data to multiple peripheral devices in an alternating pattern. In some examples, the isochronous transfer of data may help ensure that the peripheral devices receive timely and successful data transfers, improving the overall performance of the network of devices.

Dependent claims

An electronic device, comprising:

a wireless network interface;
one or more processors;
and
one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising:
receiving, via the wireless network interface, a message from a remote server, the message including configuration data relevant to a first peripheral device that has previously paired to the electronic device and relevant to a second peripheral device that has previously paired to the electronic device;
determining that the first peripheral device is currently communicably coupled to the electronic device;
determining that the second peripheral device is currently communicably coupled to the electronic device;
initiating a first data link with the first peripheral device;
initiating a second data link with the second peripheral device;
sending a first portion of the configuration data to the first peripheral device via the first data link;
receiving first acknowledgment data from the first peripheral device, the first acknowledgment data regarding receipt of the first portion of the configuration data by the first peripheral device;
sending, based at least in part on receiving the first acknowledgment data, a second portion of the configuration data to the second peripheral device via the second data link;
receiving second acknowledgment data from the second peripheral device;
sending, based at least in part on receiving the second acknowledgment, a third portion of the configuration data to the first peripheral device via the first data link;
receiving final acknowledgment data from the first peripheral device, the final acknowledgment data indicating that the configuration data, including the first portion, the third portion, and subsequent portions of the configuration data, have been received by the first peripheral device;
sending, based at least in part on receiving the final acknowledgment data, an instruction to the first peripheral device to update using the configuration data;
and
terminating the first data link.

15 more elements

A method comprising:

receiving a message from a remote server, the message including configuration data relevant to a first peripheral device and a second peripheral device;
determining that both the first peripheral device and the second peripheral device are currently communicably coupled to a central device;
initiating a first data link with the first peripheral device;
initiating a second data link with the second peripheral device;
generating a plurality of portions of the configuration data;
sending the plurality of portions of the configuration data to the first peripheral device and to the second peripheral device, the sending comprising alternating delivery of individual portions, of the plurality of portions, between the first peripheral device and the second peripheral device;
receiving final acknowledgment data from the first peripheral device indicating that each individual portion, of the plurality of the portions, of the configuration data have been received;
sending, based at least in part on the final acknowledgment data, an instruction to the first peripheral device to update using the configuration data;
and
terminating the first data link.

7 more elements

A method comprising:

receiving first configuration data and second configuration data from a remote server;
determining that the first configuration data are relevant to a first subset of peripheral devices associated with a central device;
determining that the second configuration data are relevant to a second subset of peripheral devices;
sending portions of the first configuration data in a first alternating pattern to the first subset of peripheral devices;
sending portions of the second configuration data in a second alternating pattern to the second subset of peripheral devices;
receiving final acknowledgment data from a first peripheral device of the first subset of peripheral devices indicating that each individual portion of the first configuration data has been received;
sending, based at least in part on the final acknowledgment data, an instruction to the first peripheral device to update using the first configuration data;
and
terminating a first data link over which the configuration data was sent to the first peripheral device.
