Controlling visibility of a wireless device in discoverable mode
View Patent ↗A wireless device in a discoverable mode controls its visibility by determining whether to ignore or respond to an inquiry, received from an inquiring device, based at least in part on one or more properties of the inquiring device.
1. A method to control the visibility of a wireless device in a discoverable mode, the method comprising:
while said wireless device is in said discoverable mode, receiving an inquiry from an inquiring device that is searching for discoverable devices; and
ignoring said inquiry if an identifier of said inquiring device is not ascertainable from said inquiry or if said identifier is not included in a set of identifiers of one or more devices previously connected to said wireless device.
2. The method of claim 1 , wherein said discoverable mode is a general discoverable mode and wherein said inquiry is a general inquiry intended to discover devices in any discoverable mode that are within range of said inquiring device.
3. The method of claim 1 , wherein said discoverable mode is a limited discoverable mode and wherein said inquiry is a limited inquiry intended to discover only devices in said limited discoverable mode that are within range of said inquiring device.
4. A method to control the visibility of a wireless device in a discoverable mode, the method comprising:
while said wireless device is in said discoverable mode, receiving an inquiry from an inquiring device that is searching for discoverable devices; and
ignoring said inquiry a) if an identifier of said inquiring device is not ascertainable from said inquiry or b) if said identifier does not correspond to any particular manufacturer or c) if said identifier corresponds to a particular manufacturer and an identifier of said particular manufacturer is not included in a set of identifiers of one or more permitted manufacturers.
5. The method of claim 4 , wherein said discoverable mode is a general discoverable mode and wherein said inquiry is a general inquiry intended to discover devices in any discoverable mode that are within range of said inquiring device.
6. The method of claim 4 , wherein said discoverable mode is a limited discoverable mode and wherein said inquiry is a limited inquiry intended to discover only devices in said limited discoverable mode that are within range of said inquiring device.
7. A method to control the visibility of a wireless device in a discoverable mode, the method comprising:
while said wireless device is in said discoverable mode, receiving an inquiry from an inquiring device that is searching for discoverable devices;
ignoring said inquiry where an identifier of said inquiring device is not ascertainable from said inquiry; and
where said identifier is ascertainable from said inquiry:
responding to said inquiry where said identifier is included in a first set of identifiers of one or more devices previously connected to said wireless device;
responding to said inquiry where said identifier is not included in said first set, said identifier corresponds to a particular manufacturer, and an identifier of said particular manufacturer is included in a second set of identifiers of one or more permitted manufacturers; and
ignoring said inquiry where said identifier is not included in said first set and said identifier of said particular manufacturer is not included in said second set.
8. The method of claim 7 , wherein said discoverable mode is a general discoverable mode and wherein said inquiry is a general inquiry intended to discover devices in any discoverable mode that are within range of said inquiring device.
9. The method of claim 7 , wherein said discoverable mode is a limited discoverable mode and wherein said inquiry is a limited inquiry intended to discover only devices in said limited discoverable mode that are within range of said inquiring device.
10. A wireless device comprising:
a wireless communication interface able to cause said wireless device to be in a discoverable mode and through which said wireless device is able to receive an inquiry from an inquiring device that is searching for discoverable devices;
a processor coupled to said wireless communication interface; and
a memory coupled to said processor,
wherein said memory is to store a set of identifiers of one or more devices previously connected to said wireless device, and
wherein said memory is to store code which, when executed by said processor while said wireless device is in said discoverable mode, ignores said inquiry if an identifier of said inquiring device is not ascertainable from said inquiry or if said identifier is not included in said set.
11. The wireless device of claim 10 , wherein said wireless device is a smart card reader.
12. The wireless device of claim 10 , wherein said wireless communication interface comprises a wireless personal area network (WPAN) interface.
13. A wireless device comprising:
a wireless communication interface able to cause said wireless device to be in a discoverable mode and through which said wireless device is able to receive an inquiry from an inquiring device that is searching for discoverable devices;
a processor coupled to said wireless communication interface; and
a memory coupled to said processor,
wherein said memory is to store a set of identifiers of one or more permitted manufacturers, and
wherein said memory is to store code which, when executed by said processor while said wireless device is in said discoverable mode, ignores said inquiry a) if an identifier of said inquiring device is not ascertainable from said inquiry or b) if said identifier does not correspond to any particular manufacturer or c) if said identifier corresponds to a particular manufacturer and an identifier of said particular manufacturer is not included in said set.
14. The wireless device of claim 13 , wherein said wireless device is a smart card reader.
15. The wireless device of claim 13 , wherein said wireless communication interface comprises a wireless personal area network (WPAN) interface.
16. A wireless device comprising:
a wireless communication interface able to cause said wireless device to be in a discoverable mode and through which said wireless device is able to receive an inquiry from an inquiring device that is searching for discoverable devices;
a processor coupled to said wireless communication interface; and
a memory coupled to said processor,
wherein said memory is to store a first set of identifiers of one or more devices previously connected to said wireless device and a second set of identifiers of one or more permitted manufacturers, and
wherein said memory is to store code which, when executed by said processor while said wireless device is in said discoverable mode, ignores said inquiry if an identifier of said inquiring device is not ascertainable from said inquiry, and where said identifier is ascertainable from said inquiry:
a) responds to said inquiry where said identifier is included in said first set,
b) responds to said inquiry where said identifier is not included in said first set, said identifier corresponds to a particular manufacturer, and an identifier of said particular manufacturer is included in said second set, and
c) ignores said inquiry where said identifier is not included in said first set and said identifier of said particular manufacturer is not included in said second set.
17. The wireless device of claim 16 , wherein said wireless device is a smart card reader.
18. The wireless device of claim 16 , wherein said wireless communication interface comprises a wireless personal area network (WPAN) interface.
