FIRST LET US KNOW ABOUT TYPES OF BLUETOOTH !
bluetooth. classic or LE
bluetooth classic is basically a series of specialized serial connections over radio. Bluetooth LE is more like a shared database you can read or write very small values to
bluetooth is a collection of protocol for sending data over 2.4ghz radio
it is MUCH slower than wifi but uses less power
channels are smaller too, so it can handle more interference
the tricky thing about bluetooth is it isn’t just one protocol. There are two main classes of bluetooth.
- “classic” or 3.0
- “low energy” or 4.0
actually intercepting bluetooth is hard to do with just a normal adapter because there is no way to predict when channel hops will occur
if you have an SDR you can observe all channels simultaneously thoulgh
it isn’t like wifi where you can switch to monitor mode and conceivably channel-hop to all channels very quckly
only one signal can be active on a single channel at a time
so if bluetooth adapter detects a signal using a channel it “hops” to a free channel
bluetooth operates in an “ISM band” so there is a LOT of interference
I had my 2.4ghz jammed by a faulty microwave oven just a few months ago
usually you need specialized radio hardware
like a hackRF or limeSDR
its really expensive and really hard to use
you need to know physics and math to use it
Ubertooth One is a cheap, open-source Bluetooth network sniffer. … The Ubertooth allows you to use Bluetooth in monitoring mode. This “promiscuous” mode makes the radio pass everything that it picks up onto the host computer.
It is by the same people that made the hackRF
ubertooth is cheaper but the hackRF is WAY more adaptable. Like it can hack cars and doors and drones and cameras and even satelites
and even television.
not that I recommend it, but you can run a (small) pirate tv station from a hackrf.
I use mine to watch tv too
it transmits ATSC radio signals
it transmits ANY radio signals
if your signal is stronger than the TV station it overrides the tv signal
this is VERY illegal, I don’t recommend doing it
the hackRF is a very expensive and delicate device
if you don’t have the right antenna you could build up a standing wave and fry it
also the police will come if you do bad things
they can triangulate your position
its this if you are wondering
if you have the money get a limeSDR though, it supports full duplex mode and is faster
