Apparatus and methods to communicate audio data from either an active wireless device or a requesting wireless device to one or more audio reproduction devices that are simultaneously communicatively coupled to both the active wireless device and to the requesting wireless device are disclosed. Responsive to a request from the requesting wireless device to transmit audio data to the one or more audio reproduction devices, the active wireless device determines whether to transmit audio data from the requesting wireless device based at least in part on an audio status of the active wireless device and a set of predetermined arbitration criteria that prioritizes among applications and operating system processes that generate the audio data.

Audio data routing between multiple wirelessly connected devices

Systems, methods, and computer-readable medium are provided for managing connections of user devices. For example, two source devices may be configured to maintain a data stream with one another. The data stream may enable the two source devices to identify one or more connections between each other and at least a third device. In response to receiving an event that indicates content to be provided to the third device, the data stream may be used by the source devices to configure their network connections with the third device.

Managing connections of a user device

A transport for data communication can be selected based on current data communication activity. A master device and a slave device can establish a control channel on one transport and one or more data channels. A master device can determine which transport should be used for the data channel(s) based on real-time status information about the data exchange and can coordinate with the slave device to switch the data channel(s) to a different transport when appropriate.

Dynamic transport switching in inter-device communication

A central wireless communication device communicates with a peripheral wireless communication device to provide an interactive alert notification service. The central wireless communication device obtains alert notification settings for application categories for the peripheral wireless communication device. In response to receiving an alert notification belonging to an application category enabled for the peripheral wireless communication device, the central wireless communication device sends an alert notification message that includes a unique identifier associated with the alert notification to the peripheral wireless communication device. In response to receiving an information request message that includes the unique identifier and one or more parameters, the central wireless communication device sends one or more information response messages that include the unique identifier and values for at least one of the one or more parameters to the peripheral wireless communication device.

Bluetooth alert notification service

In order to reduce latency and overhead during the device discovery process, operations involved in pairing of two electronic devices may be predefined. In particular, when a user specifies a new electronic device in a list of their electronic devices, a computer provides a notification to these electronic devices. In response to the notification, a given one of the electronic devices generates encryption information and identification information for the given electronic device, and provides this encryption information and identification information to the new electronic device via a network (such as the Internet). Then, the new electronic device generates encryption information and identification information for the new electronic device, and provides this encryption information and identification information to the given electronic device via the network. This pairing information may subsequently facilitate secure wireless communication between the two electronic devices.

Predefined wireless pairing

Techniques for discovering and/or advertising services are described herein. A first bitmask is received from a remote device over a wireless network, the first bitmask having one or more bits that have a predetermined logical value. Each bit represents a particular service provided by the remote device. A logical operation is performed between the first bitmask and a second bitmask locally generated within a local device, where the second bitmask represents a service being searched by the local device. It is determined whether the remote device is potentially capable of providing the service being searched by the local device based on a result of the logical operation.

Efficient service discovery for peer-to-peer networking devices

An electronic device is described. When this electronic device transmits a request packet to another electronic device with a discovery request, the electronic device stores information specifying the discovery request. If a response packet with an answer to the discovery request is received from the other electronic device, the electronic device stores additional information included in the answer. This additional information specifies a position in an information hierarchy in the other electronic device and a data format associated with the position. By partially caching the information and the additional information, the electronic device may significantly reduce the number of request and response messages, and thus the delay, when the electronic device subsequently accesses data in the information hierarchy.

Caching of a remote data structure based on requested information

An electronic device is described. When this electronic device receives a packet containing an address from another electronic device, the electronic device determines if a connection has already been established with the other electronic device using another address. If so, instead of establishing another connection with the other electronic device using the address, the electronic device modifies the packet by replacing the address with the other address so that it appears as if the packet was received via the connection with the other electronic device using the other address. In this way, the electronic device may avoid duplicate connections with the other electronic device, which can occur in communication protocols in which encoded information in advertising frames that specifies an address of the other electronic device is periodically changed.
