Bluetooth is a popular method of wirelessly transferring data between two devices such as your phone and your headphones, your media histrion and a speaker, or your iPad and a keyboard. It’due south ane of the virtually widely used wireless engineering science in the world, co-ordinate to the Bluetooth Special Interest Group. More than than 4.6 billion Bluetooth products are expected to ship this yr alone, and that number will likely increase to more than 6 billion per twelvemonth past 2024.
Bluetooth is all great when it works. Merely if yous’re someone who likes to play around with these kinds of continued gadgets, you know it tin be frustrating when there’s a hang-up pairing the two. Hither are some mutual causes of pairing problems as well as advice on what yous can do about them.
Why Bluetooth pairings fail
Bluetooth depends on both hardware and software to piece of work properly. And then if your devices can’t speak a common Bluetooth language, they won’t be able to connect.
In full general, Bluetooth is astern compatible: Bluetooth devices supporting the Bluetooth 5 standard should withal be able to pair with devices using, say, the ancient Bluetooth two.i, launched back in 2007.
The exceptions are gadgets that use a low-energy version chosen Bluetooth Smart, which works on a different protocol than older, or “Classic” Bluetooth devices. Bluetooth Smart devices are not astern uniform and won’t recognize (or pair with) older devices that support Classic Bluetooth.
However, if a device supports Bluetooth 4.0 (in some cases), four.ii (in about cases) or 5.0 and higher (in most cases), it should recognize both Bluetooth Smart and Classic. Bluetooth 4.0 devices volition be officially labeled Bluetooth Smart Ready. In the case of Bluetooth 4.2 and 5 and higher, it’s expected.
Gadgets that usually employ Bluetooth Smart include personal health gadgets such every bit fitness bands or heart-rate monitors. These gadgets will but pair with a smartphone or tablet that besides uses Bluetooth Smart – or are Bluetooth Smart Ready.
Virtually smartphones are Bluetooth Smart uniform. That includes iPhones running iOS seven and newer and Android phones running 4.3 or newer. Ensure your phone is running the latest version of its operating system – but if your device isn’t new enough to run relatively electric current software, you may not exist able to pair it with that fitness band.
Devices also come with specific Bluetooth profiles. If Bluetooth is the common language connecting devices, yous can recollect of a profile as a dialect associated with a sure use. For example, you probably aren’t going to be able to connect a mouse and a photographic camera considering a photographic camera doesn’t support the Human Interface Device Profile. Merely if both a mobile phone and a wireless headset back up the Hands-Gratis Contour, you should exist able to pair them.
However, if the pairing failure is a thing of user fault, there are steps you lot can take to go your devices happily communicating with each other. If yous have a multipoint Bluetooth device, check out our tips on solving problems with Bluetooth multipoint pairing.
What you can exercise most Bluetooth pairing failures
1. Brand certain Bluetooth is turned on
You should see the picayune Bluetooth symbol at the superlative right of the screen if you have an Android device. For iOS and iPadOS, you’ll need to go into the settings to enable and disable Bluetooth. Windows users will discover Bluetooth in Settings > Devices > Bluetooth (or you lot may take a shortcut on your taskbar). Mac users volition find a Bluetooth status icon on the menu bar.
2. Determine which pairing process your device employs
The process for pairing devices can vary. Sometimes, for example, it involves borer a lawmaking into your phone or computer. Other times, you can but physically affect your phone to the device you want to pair information technology with (y’all’ll see this selection with phones and devices that take NFC, or Nearly Field Communications, as a feature. It’s commonly found on Android phones).
If yous’re non sure how to pair a device, refer to its user guide; yous can unremarkably find one by searching online.

After removing a device, showtime at step 1 on this listing.
Some speakers and headphones tin can store pairing for multiple devices. Nevertheless, there is a limit to the number of devices’ pairing information that they can store. If you lot’re having trouble pairing headphones or a speaker that have been paired to many devices in the past, you may need to reset your headphones or speakers to clear out all of the pairings and so you can start fresh. Search “reset” and your device name for instructions from the manufacturer on your specific model.
7. Charge up both devices you’re trying to pair
Some devices have smart power management that may turn off Bluetooth if the battery level is as well low. If your telephone or tablet isn’t pairing, make certain it and the device you’re trying to pair with have plenty juice.

Other products (like the Sony WH-1000SM4 headphones, Bose QuietComfort Earbuds, and Soundcore Freedom 3 Pro earbuds) require installing an app and turning on the ability to connect two devices.
If you can’t connect to a previously paired multipoint device
Multipoint Bluetooth devices can connect to two devices simultaneously but can be paired with many devices. If your multipoint Bluetooth production isn’t automatically connecting to your usual 2 devices, it may exist paired with a 3rd device.
If you use an app to select multipoint devices, get into the app and toggle on the ii devices you want to exist simultaneously connected.
If you don’t apply an app to select your multipoint devices, y’all will demand to re-pair the device that has lost its connection. Follow these 2 simple steps.
1. Use your multipoint device with the Bluetooth device that is still actively paired with multipoint.
2. Re-pair the device that has lost the connection.
