1. A method for communication, comprising:after a data source device discovers a first device in a device group based on a group identifier, pairing the first device with the data source device based on the group identifier to obtain pairing information, the device group identifier uniquely identifying the device group, wherein
a status of each device in the device group is set as visible to one or more devices outside the device group,
devices in the device group are identified to the one or more devices outside the device group by the group identifier, and
the pairing information is generated by the first device using the group identifier and an identifier of the data source device;
transmitting a notification message from the first device to one or more other devices in the device group, the notification message including an instruction to update a status of each of the one or more other devices in the device group to be invisible to the one or more devices outside the device group; and
providing the pairing information to a second device in the device group, the pairing information being used for establishing a connection between the second device and the data source.
