How to connect multiple bluetooth devices to a single device

Most people have Wi-Fi routers in their homes to connect them to the internet. But have you ever heard of a Bluetooth router? With the release of new technology such as a Bluetooth Hub, you may be wondering what you might need it for.

For a start there are more devices and gadgets manufactured that are now wireless. These devices are considered more convenient as there are no annoying wires to plug in, get tangled or create an awful mess around electronics.

But with these wireless devices, you need something to connect them all to a source so you can use them effectively. So this is where your Bluetooth Hub comes in.

What is a Bluetooth Hub?

Bluetooth is a technology that you may use on a daily basis. Yet it has two significant drawbacks. The first drawback is that Bluetooth devices can only be paired on a one-to-one basis. Secondly, the range of Bluetooth is short which means many devices cut out when you move more than 30ft away from the connection source.

One of the leading Bluetooth Hub brands on the market is the Cassia Bluetooth Hub and it can solve both of these problems. The Hub is a white cylindrical device that’s about 8″ in length and 5″ in diameter.

At the back of the Hub is a USB 2.0 port, an Ethernet port, power adapter and LED indicator. The Hub can be hooked up straight through the Ethernet or through the Wi-Fi router easily. But depending on the brand the device could operate differently. So how do Bluetooth Hubs work?

How Does a Bluetooth Transmitter and Receiver Work?

There are many types of Bluetooth devices you can connect to that perform other tasks. All it needs is a Bluetooth transmitter to make pairing possible. They work by decoding information such as songs into a transferable format before transmitting that information through radio waves to the receiver.

The transmitter produces audio frequencies which are then detected by the receiver. Together the transmitter and the receiver create a pathway through which data can be transferred.

In the modern world, Bluetooth is an important feature for most applications including mobile phones, TVs, laptops and speakers. If you’re looking for any Bluetooth device it should support version 4.0 as it’s the latest Bluetooth transmitter. But version 2.1 is also more than adequate for everyday applications. With version 2.1 you can pair devices such as Bluetooth headphones or speakers.

You should also consider the range of the Bluetooth transmitter. For instance, if you’re using Bluetooth speakers and your transmitter is inside but you want to hear your music outside you’ll need a device with a longer range. This will prevent the radio signal being interrupted.

As mentioned before standard devices allow for a range of up to 30ft but with Bluetooth Hubs you’re able to connect devices from as far as 1000ft away.

Connect Multiple Devices

Depending on the brand you can pair and stay connected to the Hub with up to 22 devices. You can organize these devices into groups so you can access them quickly and easily. Here’s how to connect multiple Bluetooth devices at the same time.

Some brands such as the Cassia allow you to set up your Bluetooth router through your SmartPhone. If your device has the same feature it should be compatible with Android and Apple applications.

Your SmartPhone application allows you to manage your paired Bluetooth devices easily even when you’re not at home or near the Hub. The 22 devices can all be different from speakers to printers and even TV sets.

Simply download the compatible app on your SmartPhone so you can pair it to your Hub. Switch the Hub on either by using a specific button and use the Bluetooth on your phone to connect to the Hub. Turn on all your Bluetooth receivers so the Hub can connect to them.

On your mobile application that’s compatible with your Hub, it will show all your Bluetooth devices that are turned on. Here you can control the devices straight from your mobile phone. Easily turn on TVs, lights, kettles and radios with a click of a button through Bluetooth transmitters & receivers.

What if Your Device Doesn’t Have Bluetooth?

Not all electronic devices have Bluetooth receivers. In order to convert your device, you’ll have to purchase a portable Bluetooth receiver that you can connect to your device via a cord.

You can turn an ordinary device such as a pair of headphones into a Bluetooth receiver by simply plugging in a portable receiver. People do this with myriads of applications so they can easily control the devices using their Bluetooth Hub.

Can you Connect Multiple Speakers?

If you have an event and you have no idea how to use a soundboard or how to connect all your speakers at the same time, a hub can help you with the task. This is of course if the speakers have Bluetooth receivers.

Simply turn all your Bluetooth speakers on so they can be discovered by the Bluetooth router. Here you can play music with SoundCloud, YouTube, Deezer or even through your phone’s music media via your SmartPhone application.

You can pair four or more speakers at the same time and place them all over the house to transmit sound.

Troubleshooting when Connecting Bluetooth Devices

If you’re experiencing interference or signal dropouts, scan the environment you’re using your Bluetooth device in. The quality of the Bluetooth connection can be negatively affected by concrete walls, microwaves and other wireless devices such as portable radios or cordless telephones.

  1. The hub makes the route longer. What is the voice delay when working with a microphone? What bluetooth versions are able to interact?

  2. Hi… the cassia bluetooth hub is no longer available Can you recommend a Bluetooth hub that will connect 20 Headphones Bluetooth 3D Bluetooth 5.0 Wireless simultanously…

  3. I need a bluetooth hud that connects 4 head sets. and the hub pairs to bluetooth tv to simultaneously listen to programs and movies

  4. I am lucky my stereo has an USB port, so each time I turn on my stereo, my receiver gets charged. However, I see there are awesome options in the website you suggested, like the receiver that can hold information for up to six different devices. Thanks.

  5. I am planning a backyard tailgate party. I want to show the superbowl using my roku projector. I want each car to be able to receive the sound thru their own speakers or radio. Is this possible? Planning on having movie nights as well and due to covid every one can remain in their cars.

    • This situation might be easier with an FM band transmitter, in some ways. Especially if some don’t have a Bluetooth receiver in their car. Range on the Bluetooth might be a problem; but it’s digital sound so if it works, it works. The FM idea is analog, so it’s more prone to background noise and possible causing or receiving interference, but while the sound quality will fall as the receiver is more and more distant from the transmitter, it still can be heard. Digital works and then it doesn’t, in terms of range. I don’t know what costs or complexity you might face in setting up this backyard broadcast. With FM, you have to find a channel on which no other station is operating, especially a legal station. You may have various power output options with FM, but you should keep it as low as necessary, not the maxium power, to prevent unintentional interference. If this is a infrequent use, and not prolonged events, then you’ll avoid any possible leagal problems. The FCC won’t bother if it’s essentially a “once and done” party.

  6. I want to pair two headsets via Bluetooth to my iPad Air so my kids can watch movies in the car on long journeys. They are little so I don’t want cords hence Bluetooth technology would work great for them.

  7. Need to connect up to 100 blue tooth capable hearing aids for mass meetings. Needs to be done as the wearer walks in the door with only a few milliseconds latency
    Are there any devices like this on the market yet?
