Abstract: The described embodiments transfer an activity from a source electronic device to a companion electronic device. The source electronic device receives activity information describing an activity performed in a first application at the source electronic device, determines an activity identifier for the activity information, and broadcasts an activity advertisement comprising the activity identifier. Upon receiving the activity advertisement, the companion electronic device determines whether a second application that is associated with the first application is available at the companion electronic device. If the second application is available, the companion electronic device requests extended activity data from the source electronic device. The source electronic device responds by sending extended activity data from the first application to the companion electronic device.

Abstract: Messaging between a companion device and an accessory device is controlled such that different modes of communication may be utilized. The different modes can implement different messaging strategies, each of which is intended for efficient power management, in view of the limited electrical power that is typically available at the accessory device. A received request message for sending from the companion device to the accessory device is sent if predetermined conditions apply, and similarly for messages from the accessory device to the companion device.

Abstract: Systems, methods, and devices can allow applications to provide complication data to be displayed in a complication of a watch face. A client application can create a complication data object according to a template to efficiently select how the complication data is to be displayed. For example, a complication controller on the watch can receive new data and determine which template to use. The complication data object can be sent to a display manager that can identify the selected template and display the data according to the template.

Abstract: The embodiments set forth a technique for coordinating notifications across computing devices placed onto a wireless charging apparatus. According to some embodiments, the technique can involve the wireless charging apparatus (1) receiving, from a first computing device, first information that includes (i) a first unique identifier (ID) associated with the first computing device, and (ii) one or more unique IDs that are each associated with a respective auxiliary computing device known to the first computing device. Subsequently, the wireless charging apparatus can receive, from a second computing device, second information that at least includes a second unique ID associated with the second computing device. Finally, the wireless charging apparatus can, in response to determining that the second unique ID is included in the one or more unique IDs, and cause both the first and second computing devices to display respective notifications in a coordinated manner.

Abstract: An approach is provided for providing adaptable schema based payloads for state advertisement messages. In some implementations, multiple schemas (e.g., payload data and structure definition) can be used to flexibly and dynamically define advertisement message payloads. For example, the computing device can use advertising message to share and broadcast information between devices by using adaptable schema based payloads. The computing device can store schemas, receive service advertising data, and determine a schema for encoding service advertising data into an advertising message. The computing device can generate the advertising message, encode a schema identifier into the advertising message header, and encode device state data into the advertising message payload according to the determined schema.

Abstract: The described embodiments transfer an activity from a source electronic device to a companion electronic device. The source electronic device receives activity information describing an activity performed in a first application at the source electronic device, determines an activity identifier for the activity information, and broadcasts an activity advertisement comprising the activity identifier. Upon receiving the activity advertisement, the companion electronic device determines whether a second application that is associated with the first application is available at the companion electronic device. Then, the companion electronic device configures the second application and commences performing the activity with the second application at the companion electronic device.

Abstract: Methods and apparatuses for wireless communication devices to discover each other and share information are described. Wireless communication devices transmit and receive messages to identify compatible wireless communication devices. The messages include indicators for a communication service and one or more user identification values. A scanning wireless communication device identifies a message from a broadcasting wireless communication device that satisfies a set of matching filter criteria and extracts user identification values from the message. The scanning wireless communication device compares the extracted user identification values to a local set of user identification values. When an extracted user identification value from the message matches a user identification value in the local set of user identification values, the scanning wireless communication device establishes a connection to the broadcasting wireless communication device according to the communication service indicated in the message.
