BROADCASTING COMMUNICATIONS OVER AN ADVERTISING CHANNEL

摘要

Apparatuses, methods and storage media for communications between a peripheral device and host device in the absence of established connection between the devices are described. In one instance, an apparatus may include a host processor, a memory, and a controller coupled with the host processor and the memory and configured to detect for a communication broadcasted via an advertising channel by a peripheral device; determine whether a unique identifier previously communicated to the peripheral device is present in the detected communication; and provide a message corresponding to the communication to the host processor for processing, based on a result of the determination. The apparatus communicates with the peripheral device via a connection established over communication channels. The advertising channel and the communication channels are different. The connection between the devices is not established when the communication is broadcasted via the advertising channel. Other embodiments may be described and claimed.

主权项

1. At least one non-transitory computer-readable medium comprising executable instructions that, in response to execution of the instructions by a computing device, enable the computing device to provide a communications controller to:
initiate a scan of an advertising channel for communications initiated by a peripheral device external to the computing device, in response to the computing device entering a power-saving state or a power-off state; detect for a communication broadcasted via the advertising channel by the peripheral device; determine whether a unique identifier previously provided to the peripheral device is present in a detected communication; and communicate a command to cause the computing device to resume a power-on state, based on a result of the determination, wherein the computing device is configured to communicate with the peripheral device via a connection established over at least one of a plurality of communication channels while the computing device is not in the power-saving or power-off state, wherein the advertising channel and the communication channels are different channels.
