Abstract: A monitoring arrangement for an exercise device generates data items representing exercise activity by a user, performs a connection process for establishment of an end-to-end connection to a user device, broadcasts progress data that represents data items generated during the connection process, and sequentially transmits, on the end-to-end connection data items, generated after establishment of the end-to-end connection. The user device receives the progress data and presents, during the connection process, progress of the exercise activity based on the progress data. After establishment of the end-to-end connection, the user device presents progress of the exercise activity based on data items received on the end-to-end connection. The combination of broadcasting and sequential transmission obviates the need for the user to wait for the end-to-end connection before starting exercise activity.

Abstract: An electronic tag, which may be used in a data management system, comprises a Bluetooth transmitter and an RFID transmitter. The Bluetooth transmitter is operable to transmit first data packets. The RFID transmitter is operable to transmit second data packets. The first data packets comprise a first identifier, ID1, and the second data packets comprise a second identifier, ID2, which is different from ID1. A portable electronic device is configured to, upon receiving one of the first data packets by a Bluetooth receiver, selectively activate an RFID receiver for the second data packets, thereby enabling transfer of ID2 from the electronic tag irrespective of the data transfer capacity of the first data packets.
