One to many bluetooth devices

Connect one bluetooth device as multiple devices

I realize that multiple bluetooth devices can be connected to a master device. My question is simple: can a single bluetooth chip with a single MAC address connect to another bluetooth device as more than one client? EDIT: Basically is it possible to accept multiple bluetooth clients with the same MAC address, if not can the client computer connect using different faux addresses? For example, I am writing software that emulates a wiimote for the Wii/WiiU. I am hoping to emulate more than a one wiimote using a single bluetooth usb dongle. If a hack is needed C or C++ code would be prefered. Preferably for windows if platform dependent. Please be descriptive in any answers.

4.4 Multiple Devices per Host/Multiple Hosts per Device

Bluetooth HIDs shall set no limitation on the number of devices per host (up to the seven simultaneous active devices allowed per piconet). All trusted devices (devices that have either been authenticated or have no security procedures required) shall be allowed to have simultaneous connections to the host, if the host so desires. For example, multiple Bluetooth mice and keyboards are allowed. The behavior in this case shall be the same as for the USB case; i.e., input from all devices is allowed and the data streams are logically ORed together.

Similarly, a single Bluetooth HID may have established a bond or have its address known by multiple hosts. However, if it has declared itself virtually cabled, it is mandatory that the device only support a single host connection, and only one control and one interrupt L2CAP channel to that host, at one time (see SDP attribute HIDVirtualCable). If the device has not declared itself virtually cabled, it is still recommended that the device only support a single host connection at one time, i.e. no more than one SDP, control, and interrupt channel may be open at a time. A Bluetooth HID that implements the Virtual Cable feature shall have sufficient resources to remember a minimum of two hosts, and four hosts is recommended, to make later reconnection easier without passkey entry.

How to set up Bluetooth multipoint on your headphones

Bluetooth multipoint lets you connect two devices at once to your headphones. It can greatly enhance your experience, plus it’s easy to use.

Bluetooth headphones make it easy to listen to music or podcasts almost anywhere. But if you’re the kind of person who jams out to tunes while working and doesn’t want to miss your Slack calls, take advantage of Bluetooth multipoint.

What is Bluetooth multipoint?

Bluetooth might be most well-known for its nearly effortless ability to connect headphones to a computer or smartphone. Multipoint extends this capability to more than one device at a time. It gets more complicated than that, though. For an in-depth look, check out our guide to multipoint.

The advantage of this becomes evident if you think of an everyday use case. For example, if you’re listening to music from your phone with wireless earbuds and a Slack call comes in on your laptop, multipoint will deliver that alert without any hassle and will (usually) let you switch devices seamlessly. Typically, multipoint involves a main device and a secondary one, but again this varies. Not every headset model supports multipoint, but some of the most well-known do. We’ll get into some specifics about the most popular brands of headphones shortly.

What’s the difference between simple and advanced multipoint?

Simple Bluetooth multipoint drops a call on one device if another one arrives somewhere else. Advanced, on the other hand, maintains both and puts the previous one on hold. Furthermore, some devices support the ability to push through notifications from one device, like a computer, without completely stopping music playback through another, such as a phone. The specifics depend on your model of headphones and playback devices.

Keep in mind that your ears can really only listen to one stream of information at a time. If you’re mastering multiple audio tracks across files and devices, multipoint (or even Bluetooth headphones in general) may not be the solution for you.

How do you use Bluetooth multipoint?

While the specific instructions for using Bluetooth multipoint with your headphones will vary, we’ll cover some of the most popular brands, and go over the basic phone and computer scenario here. However, know that plenty of other options exist. Check the manual or manufacturer’s website to see if your favorite pair of headphones support Bluetooth multipoint.

How do you use Bluetooth multipoint with Sony headphones?

Sony’s most well-known model of noise canceling Bluetooth headphones, the Sony WH-1000XM4, supports multipoint. To use it:

1. Pair the headphones to a computer and phone
2. Open the Sony Headphones Connect app
3. Under the System tab, enable “Connect to 2 devices simultaneously”
4. Under the Status tab, tap on the name of the currently connected device
5. From the list of available devices, select the other one you wish to connect
6. Ensure both devices now appear under “Device Currently Being Connected”
7. You can now listen to music from either source and switch to an incoming call by tapping the touch sensor twice quickly

Bluetooth multipoint only works with the AAC Bluetooth codec. So, don’t expect the ultimate in audio quality—especially on Android devices. But it works well enough for casual listening at your desk or the gym.

How do you use Bluetooth multipoint with Bose headphones?

Bose’s flagship wireless headphones model, the Bose Noise Canceling 700, supports Bluetooth multipoint. To use it:

1. 1. Open the Bose Music app

   5. To add a new device while synced to another, select “Add new”

   The Bose Noise Canceling 700 keeps a list of up to eight devices, but only two will work with Bluetooth multipoint simultaneously. Play music or videos on one, then pause and switch between them as desired.

   How do you use Bluetooth multipoint with Jabra headphones?

   2. Put your headphones back into pairing mode
   3. Pair up the second device
   4. One device can now play music and movies, and the other is the secondary for taking calls or answering notifications

   How do you use Bluetooth multipoint with Anker headphones?

   Some models of Anker Soundcore headphones, including the Life Q35 and Q30, support Bluetooth multipoint. Check your manual to be sure, but in general:

   1. Connect to one device via Bluetooth
   2. Enter Bluetooth sync mode as if you were adding a new device
   3. Connect to your Anker headphones on another device
   4. The first device is the main, and the other becomes a secondary

   The main device is the one you’ll play music and movies on. It will take priority unless a phone call comes in, which supersedes all other content. To switch between devices, pause playback on one and then start it on the other.

   How do you use Bluetooth multipoint with Samsung Galaxy Buds?

   

   You can take your Samsung Galaxy Pro Buds to the gym, listen to music on your phone, and still have your tablet ping you work notifications, all automatically—if you stay within the Galaxy ecosystem.

   Things get a bit more interesting if you own the Samsung Galaxy Buds Pro, Galaxy Buds 2, Galaxy Buds Live, or Galaxy Buds Plus and a compatible Samsung device. None of these models support Bluetooth multipoint, but each headset can automatically switch devices as soon as you hit play on any device, as long you sync them properly on each. There is no need to swipe, tap, or dive into settings menus. Be sure you’re signed in to the same Samsung account on all your Galaxy devices so that this feature works correctly.

   If you’ve got the Samsung Galaxy Buds Pro but no other compatible Galaxy device, you can still switch between sources manually:

   1. Open the Galaxy Wearable app
   2. Tap the Menu icon (three vertical lines)
   3. The currently connected device appears at the top of the list
   4. Tap another device to connect to two devices at once

   Of course, this method means no automatic switching. Instead, you’ll have to start and stop music yourself on each device.

   How do you use Bluetooth multipoint with Sennheiser headphones?

   Certain Sennheiser headphones models support Bluetooth multipoint, including the HD 450BT, HD 350BT, MOMENTUM 3 Wireless, and PXC 550 II. The level to which it works varies, but you’ll find the setting in the Sennheiser Smart Control app under “Connection.”

   How do you use Bluetooth multipoint with V-Moda headphones?

   How do you use Bluetooth multipoint with Apple AirPods earbuds?

   

   AirPods makes for easy-to-use Bluetooth multipoint earbuds, but only if you remain within Apple’s walled garden.

   If you’re already in Apple’s cozy ecosystem, then you’ll be happy to hear that the AirPods and the AirPods Pro can switch automatically between devices. Much like the Samsung Galaxy Buds, this requires compatible Apple devices to work. Similarly, you must use the same Apple ID across all these devices. Calls take precedence, and the earbuds will switch to your iPhone if one comes in. This won’t work with any other brands’ devices. We don’t recommend that you try, anyway.

   Bluetooth multipoint can help make your listening experience seamless. As you switch between tasks and devices, your wireless headphones can do so, too. For example, think of keeping a TV show going in the background while working from home yet still getting notifications of incoming calls. The possibilities are nearly endless, and the right multipoint pair of Bluetooth headphones could change the entire way you listen to music.
