The Bluetooth Special Interest Group has cleared
a proposal to more explicitly add location awareness to the standard.
Bluetooth 2.0 and up devices will have the option of using the Global
Navigation Satellite System (GNSS) profile, which will let a GPS-aware
device share its location data with other Bluetooth hardware.
Implementing GNSS could let a smartphone share its position with a
dedicated camera, tablet, or other device without having special code.GPS
sharing already exists, but usually requires either special apps on
both sides of a connection or a dedicated receiver with software on one
end.
Companies using Bluetooth can download the new profile now. Shipping
products using the new GPS support may take some time, however, either
through firmware updates or through new hardware.
