Bluetooth hacks can take place when a hacker uses their own Bluetooth connection to gain access to your phone. However, this can only happen if your phone is within the Bluetooth range of a potential hacker. Usually, this range is around 30 feet.
How accurate is someone's location on iPhone?
How accurate are location services on iPhone? Accuracy varies widely depending on where you are, but it can be accurate to within a couple meters -- just don't count on it all the time. Location services tend to have three broad levels of accuracy: cell tower, WiFi, and GPS.
Why does Bluetooth improve location accuracy?
"Bluetooth location features fall into one of two camps: proximity or positioning," said Android Authority. "Proximity helps Bluetooth devices recognize when they are near one another. Common uses are personal property tags and marketing beacons that deliver information regarding nearby points of interest.
How do I fake my location on iPhone?
Launch Apple Maps and navigate to the location you'd like to be in. Hit the bottom of the window to get location information, and you should find the Simulate Location feature. Tap to confirm and verify if it works for your other apps.
Why is location required for Bluetooth?
By requiring location services to access Bluetooth, you ensure that the user understands their location information may leak when they use Bluetooth. In versions of Android prior to Marshmallow, the user could use Bluetooth without location services enabled, but location information could leak.

Beacons are Not Cost-Efficient As beacons do not provide a highly accurate location coverage, you might need to install more for the results to be closer to what you expected, yet that costs more money.
How does Bluetooth beacon work?
Bluetooth beacons work by transmitting packets of data that are picked up by a compatible receiving device via radio waves. These packets of data are either self-contained or are triggers to events on the receiving device, such as push notifications, app actions, and prompts.
How many blocks does a full beacon take?
It requires a total of 244 mineral blocks, with a base layer of 10 by 11.
What is Bluetooth Low Energy?
iOS 7 introduced support for Bluetooth Low Energy (BLE) iBeacons. These are small Bluetooth devices that can be placed to indicate a very specific location and the system respond in some way when they are detected. Enter a shop and an app for the shop showing you the latest offers might be one way for this to be leveraged. This would be different from usual geolocation APIs which become inaccurate when you are inside large structures (offices, malls etc.) as they cannot get a GPS fix, and WiFi coverage tends to be meshed with repeater stations
How far does WiFi range go?
WiFi has a signal range (radius) of about 300 feet (outdoors)
What would iBeacon use to determine its location?
The iBeacon would use other methods, like GPS or WiFi to determine its own location and then probably phone home that info to Apple.
Does Apple know where you are?
Apple would know the exact location of the iBeacon, therefore be able to give you a good idea of where you are.
What is the difference between accuracy and precision?
By contrast, precision means how close multiple measurements of the same thing are to each other. We can get a very good idea of precision, and for most surveying equipment the precision of the equipment is well known (the manufacturers determine this according to ISO standards).

Abhinav's answer is correct but I don't think the App developer is deliberately trying to mislead you.
Does Bluetooth improve accuracy?
This would only improve accuracy if you have an external Bluetooth enabled GPS-receiver with which the phone is attempting to connect.
Does Bluetooth carry location information?
Bluetooth itself does not carry information about location. In Bluetooth tracking devices Internet connection is needed. Then, when a signal of such a device will be recevied by a phone or a computer, the “receiver” (mobile/computer/etc.) saves data about its current location and sends the data to a cloud.
Does Apple offer indoor GPS?
Apple (and other manufacturers/service providers) will shout all day about the improved GPS/routing guidance they can offer you indoors (example; the text you're seeing in the location setti
Does turning on Bluetooth help with location?
Turning bluetooth on won't improve location accuracy or enable nearby services, unless you happen to be within range of one or more iBeacons (Bluetooth Low Energy beacons). But if you are, here's how that improves location accuracy:

Using beacons for push notifications, coupon delivery and presence detection is fairly straightforward. But if you wish to create accurate indoor positioning with beacons, things get a bit more complex.
How far away should beacons be from each other?
Make sure that the beacons are less than their signal’s reach away from each other. For example, if you have set their transmission power to equal 30m, preferred maximum distance is 20-25 metres to provide more accurate location. Also make sure that your room is large enough.
How many beacons do you need to calculate position?
Like the term says, you do need a minimum of three beacons for deducting accurate position. One exception to this are narrow corridors or other situations, where you may be able to calculate position between two beacons. Kalman filters.
Can you use Bluetooth beacons with Proximi?
Selecting hardware. Regarding the physical devices you utilize, there are dozens of Bluetooth beacon manufacturers. We highly recommend you to review the technical specifications before making any decisions. You don’t want to end up with beacons with irregular signal or weak battery life. Regarding the protocol you utilize, you can use any of the available options for positioning. However, if you utilize Proximi.io platform, you need to opt for either iBeacon or Eddystone, which are supported by nearly all beacons.
