Is Bluetooth point to point or multipoint?
Page 3 of 9: Show Bluetooth OperationBluetooth OperationPiconetsBluetooth is designed for communication over a small network called a piconet. The simplest configuration is a point-to-point piconet, with one device designed as a "master" and the other a "slave." The master initiates the communication link, and in general, has control over the network's timing. Up to seven slaves can be connected to a master in a point-to-multipoint configuration. An example of this kind of operation is a smartphone (master) connecting to multiple Bluetooth slaves—a Bluetooth headset for streaming music, a Bluetooth keyboard as an input and a second smartphone for Bluetooth-based file transfers. This kind of system implies an ad-hoc network with no fixed roles or designations. Also, a Bluetooth master can dissolve its piconet and then go join a different piconet as a slave. Here's an example of Bluetooth network organization; Network 1 is a piconet in standalone mode, Network 2 is a scatternet: A bit of history: While Bluetooth headsets have been around since the year 2000, being able to connect one to more than a single phone at the same time is a relatively new development. Multipoint technology emerged in the mid-2000s and has been continuously refined and improved ever since. But what in the world is it, and how does it work? Let’s take a look: Simple multipointIn the case of simple multipoint, a Bluetooth headset is connected to two separate devices at the same time. When one of them rings, the headset knows which one it is. So when you answer the call, the headset will automatically stream it from the right device. If you’re already talking on your first phone, the headset will alert you if there’s an incoming call on a second one. You can then pick up this second call directly from the same headset. In practice, simple multipoint is useful in many different cases. For example:
Here’s a short video that illustrates the concept rather well: Simple multipoint comes with one minor inconvenience: When you answer a second incoming call, your headset actually drops the connection to the call you’re already on. So you can inadvertently hang up on your best friend while answering a nuisance call from a telemarketer. Fortunately, something called “advanced multipoint” takes care of that issue. Advanced multipointAdvanced multipoint is almost exactly the same as simple multipoint…except more advanced. Bad jokes aside, the primary function of advanced multipoint is the same: There are two connected devices and one headset that can answer two separate calls. But – in the case of advanced multipoint – the first call is not dropped when you pick up the second incoming call. Instead, the first call is put on hold, so you can return to it once you’re done with the other one. In fact, you can keep switching between the two calls, putting them on hold interchangeably. With advanced multipoint, you can quickly yell at the bothersome telemarketer and get back to your friend at the press of a button. Advanced multipoint is becoming the standard for most new Bluetooth headsets. Triple connectivitySome of the newer professional headsets take this a step further. These headsets have a docking base with a nifty touch screen. The base unites all of your connections – from cell phone to desk phone to computer. As such, you can connect to three devices at once and control them all via the touch screen. These professional headsets let you not only switch between calls but even merge them into one conversation. So now you can make your friend yell at the telemarketer on your behalf. I discuss this triple connectivity in more detail in this blog post. The majority of today’s Bluetooth headsets have multipoint and work with multiple devices.

Early iterations were clunky, to say the least, but it has improved significantly in the time since. Multipoint allows you to connect a Bluetooth headset to two, or more, devices at once.
Can Bluetooth headphones connect to 2 devices at once?Bluetooth multipoint lets your headset connect to two source devices at once. Bluetooth multipoint was introduced with the release of Bluetooth 4.0, over ten years ago. It's a feature that allows a single Bluetooth headset to maintain simultaneous connections to at least two source devices like a laptop and smartphone.
Does Bluetooth 5.0 have multipoint?As mentioned above, multipoint doesn't allow audio from one source to play on multiple devices. That said, Bluetooth 5.0 introduced a feature that allows just this.
What is multi pair Bluetooth?Simply put, Bluetooth multipoint gives you the ability to pair two different Bluetooth sources—like your smartphone and laptop—to a compatible headphone, both at the same time.
