Hi people! Can someone please tell me does this Bluetooth SIG really able to use some technologies to track the locations of many devices?

While Broadcom invented new GNSS chip, Bluetooth SIG (Special Interest Group) designed this new GNSS profile developed for GPS data sharing. All device with Bluetooth 2.0 and higher support can use this profile to easily share GPS positioning data with other devices nearby using their Bluetooth connectivity. What it can give us? Let's think together.
First of all, any of those Bluetooth-enabled devices will be able to discover your location through your Bluetooth, thus improving indoor tracking. Secondly, in the future it can allow handheld devices to fully forget about using GPS for location tracking. And the third one is probably the most fun thing. You see, the working radius of Bluetooth is a few meters. So imagine the situation: there is one GPS-enabled device in a room, while others have no GPS tracking inside. Still all of them have Bluetooth embedded. They will share GPS data of that one device, allowing evildoers to discover that all those devices are currently in a room and not only the GPS-enabled one. It is some kind of the reversed sharing, you see?
So, the answer to your question is: yes, it apparently can. But you are not helpless in this situation and can block Bluetooth SIG GNSS profile for GPS sharing, preventing your Bluetooth device from sharing the data with other devices in the room and being discovered in such way.
