A device comprises circuitry and a transceiver in communication with the circuitry. In operation, the device is configured to cause the transceiver to: periodically send a broadcast message to indicate the availability of the device for attachment to another device; receive, from the another device, a first pre-attachment message that is sent utilizing first information sent by the device; send, to the another device, a first response that is sent in response to the first pre-attachment message and includes second information; receive, from the another device, a second pre-attachment message that is sent utilizing the second information; send, to the another device, a second response that is sent in response to the second pre-attachment message; and communicate, with the another device, data utilizing a second one of the addresses for identification in association with the another device, for data transfer in connection with a group controlled by the device. |
