It's one of the most widely used wireless technology in the world, according to the Bluetooth Special Involvement Group. More than four.vi billion Bluetooth products are expected to transport this twelvemonth alone, and that number will likely increase to more than half-dozen billion per year by 2024.

Bluetooth is all keen when it works. But if you're someone who likes to play around with these kinds of connected gadgets, you know it can exist frustrating when there's a hang-up pairing the two. Here are some common causes of pairing problems besides as communication on what you can do about them.

Why Bluetooth pairings fail

Bluetooth depends on both hardware and software to work properly. So if your devices tin can't speak a common Bluetooth language, they won't exist able to connect.

In general, Bluetooth is backward compatible: Bluetooth devices supporting the Bluetooth 5 standard should nonetheless be able to pair with devices using, say, the ancient Bluetooth 2.one, launched back in 2007.

The exceptions are gadgets that use a depression-energy version called Bluetooth Smart, which works on a dissimilar protocol than older, or "Classic" Bluetooth devices. Bluetooth Smart devices are non backward uniform and won't recognize (or pair with) older devices that support Classic Bluetooth.

Still, if a device supports Bluetooth iv.0 (in some cases), 4.ii (in most cases) or v.0 and higher (in most cases), it should recognize both Bluetooth Smart and Classic. Bluetooth iv.0 devices will exist officially labeled Bluetooth Smart Ready. In the instance of Bluetooth 4.two and 5 and higher, information technology's expected.

Gadgets that unremarkably use 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 also uses Bluetooth Smart – or are Bluetooth Smart Set.

Almost smartphones are Bluetooth Smart compatible. That includes iPhones running iOS 7 and newer and Android phones running four.three 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 current software, you may not be able to pair it with that fitness ring.

Devices as well come with specific Bluetooth profiles. If Bluetooth is the common language connecting devices, yous tin can recall of a profile as a dialect associated with a sure apply. For case, you probably aren't going to be able to connect a mouse and a camera considering a photographic camera doesn't support the Human Interface Device Profile. But if both a mobile phone and a wireless headset support the Hands-Free Profile, you should exist able to pair them.

Withal, if the pairing failure is a affair of user error, there are steps you can accept 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 do about Bluetooth pairing failures

1. Make sure Bluetooth is turned on

Y'all should see the little Bluetooth symbol at the top correct of the screen if yous have an Android device.
