PROBLEM TO BE SOLVED: To automatically receive only required information and to easily change desired distribution information just by changing the contents of a PIN code. SOLUTION: To BT-APs 25-28, codes are individually allocated for the respective contents transmitted by the BT-APs 25-28. The code '0001' is allocated to the BT-APs 25 and 27 distributing 'news' and the code '0002' is allocated to the BT-APs 26 and 28 distributing 'weather'. The codes allocated for the respective contents in such a manner are used also for the PIN codes at the time of performing Bluetooth (R) authentication. In the meantime, the code is inputted beforehand similarly in a BT-CL 29 which is an information receiving side as well. COPYRIGHT: (C)2003,JPO |
