发明名称 Data delivery through portable devices
摘要 A communications system comprises at least one first portable communications device (12) capable of wireless message transmission and at least one second portable communications device (10) capable of receiving such a message transmission. The first device (12) is arranged to broadcast a series of inquiry messages (60) each in the form of a plurality of predetermined data fields (INQ) arranged according to a first communications protocol, such as Bluetooth. For the delivery of additional data via broadcast, the first device (12) adds to each inquiry message prior to transmission an additional data field (BCD) carrying broadcast data, with the second portable device (10) receiving the transmitted inquiry messages and reading the broadcast data from the additional data field.
