Bluetooth is a popular method of wirelessly transferring data between two devices such as your phone and your headphones, your media player and a speaker, or your iPad and a keyboard. It’s one of the most widely used wireless technology in the world, according to the Bluetooth Special Interest Group. More than 4 billion Bluetooth products are expected to ship last in 2018 alone, and that number will likely almost double within the next three years.

Bluetooth is all great when it works. But if you’re someone who likes to play around with these kinds of connected gadgets, you know it can be frustrating when there’s a hang-up pairing the two. Here are some common causes of pairing problems as well as advice 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 can't speak a common Bluetooth language, they won’t be able to connect.

In general, Bluetooth is backward compatible: Bluetooth devices supporting the Bluetooth 5 standard should still be able to pair with devices using, say, the ancient Bluetooth 2.1, launched back in 2007.

The exceptions are gadgets that use a low-energy version called Bluetooth Smart, which works on a different protocol than older, or "Classic" Bluetooth devices. Bluetooth Smart devices are not backward compatible and won't recognize (or pair with) older devices that support Classic Bluetooth. (For example, an old Sony Ericsson phone sporting Bluetooth 3.0 won't be able to connect to a Bluetooth Smart device.)

However, if a device supports Bluetooth 4.0 (in some cases), 4.2 (in most cases) or 5.0 (in most cases), it should recognize both Bluetooth Smart and Classic. Bluetooth 4.0 devices will be officially labeled Bluetooth Smart Ready. In the case of Bluetooth 4.2 and 5, it's expected.

Gadgets that commonly use Bluetooth Smart include personal health gadgets such as fitness bands or heart-rate monitors. These gadgets will only pair with a smartphone or tablet that also uses Bluetooth Smart – or are Bluetooth Smart Ready.

Most smartphones are Bluetooth Smart compatible. That includes iPhones running iOS 7 and newer, Android phones running 4.3 or newer, Windows Phone 8.1 devices, and all BlackBerry 10 devices. 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 band.

Devices also come with specific Bluetooth profiles. If Bluetooth is the common language connecting devices, you can think of a profile as a dialect associated with a certain use. For example, you probably aren't going to be able to connect a mouse and a camera because a 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 be able to pair them.

However, if the pairing failure is a matter of user error, there are steps you can take to get your devices happily communicating with each other.

What you can do about pairing failures

1. Make sure Bluetooth is turned on. You should see the little Bluetooth symbol at the top of your phone’s screen. If you don’t, go into the settings to enable it.

2. Determine which pairing process your device employs. The process for pairing devices can vary. Sometimes, for example, it involves tapping a code into your phone. Other times, you can just physically touch your phone to the device you want to pair it with (you'll see this option with phones and devices that have NFC, or Near Field Communications, as a feature. It's commonly found on Android phones). Or in the case of the Bose SoundLink, you only have to hold down a button on the speaker to pair it with a phone.

If you’re not sure how to pair a device, refer to its user guide; you can usually find one by searching online.

3. Turn on discoverable mode. Let’s say you want to pair your phone with your car’s infotainment system so you can enjoy hands-free calling, texting and navigation. First, go into your phone’s settings and tap on Bluetooth; doing so makes the phone visible to the car. Then depress the buttons on your car's infotainment system, usually on the steering wheel or center stack, to get it looking for the device.

Once it finds your phone, the car may ask for a numeric code you need to confirm or input on your phone. After you do so, the devices should be paired. Keep in mind your phone or your car may only stay in discoverable mode for a few minutes; if you take too long, you’ll need to start over.

4. Make sure the two devices are in close enough proximity to one another. While you wouldn’t think someone might try to pair an iPad with a keyboard if the two weren’t sitting right next to each other, it’s probably worth noting that you should make sure any devices you're trying to pair are within five feet of one other.

5. Power the devices off and back on. A soft reset sometimes can resolve an issue. With phones, an easy way to do this is by going into and out of airplane mode.

6. Remove old Bluetooth connections. Say that faithful Bluetooth speaker usually connects to your partner's smartphone instead of yours. If you're having trouble pairing your phone with the speaker, it could be because the speaker is trying to connect to the old device. Some older devices are very simple. They just try to connect with the last thing they paired with. If a Bluetooth device was previously paired with something else, turn off that other gadget. And if you are no longer planning on using that other gadget, unpair it from your Bluetooth device to prevent future issues. In iOS settings, you can remove a device by tapping on its name and then Forget this Device. In Android settings, tap on a device’s name, then Unpair. After removing a device, start at step 1 on this list.

You can also reset Bluetooth on devices that can pair to more than one device. This clears all pairings from the device so you can start fresh. Search "reset" device name to instructions from the manufacturer.

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 too low. If your phone or tablet isn't pairing, make sure it and the device you're trying to pair with have enough juice.

8. Delete a device from a phone and rediscover it. If your phone sees a device but isn’t receiving data from it, sometimes it helps to start from scratch. In iOS settings, you can remove a device by tapping on its name and then Forget this Device. In Android settings, tap on a device’s name, then Unpair. After removing a device, start at step 1 on this list.

9. Get away from the Wi-Fi router. Another potential obstacle to successful pairing is interference from devices that use the same spectrum, such as your Wi-Fi router. Wi-Fi has been designed to cope with this, but it might not be a good idea to have your devices directly on top of the router.

10. Move away from a USB 3.0 port. Interference from USB 3.0 is also possible. Newer laptops, for example, often have the higher-speed USB 3.0 port, so if the connection isn't happening, try pairing your Bluetooth gadgets away from the computer.

11. Make sure the devices you want to pair are designed to connect with each other. Whether it’s a headset, speaker, mouse, keyboard, camera or something else, your device has a specific profile that spells out what it can connect with. If you’re not sure, check the user manual.

12. Download a driver. If you’re having problems pairing something with your PC, you might be lacking the correct driver. The simplest way to figure this out is to do an online search for the name of the device you’re trying to pair along with the word “driver.”

13. Update the hardware’s firmware. Some automotive audio systems have been known to not pair with phones because the Bluetooth drivers in these systems didn’t work with Bluetooth 4.0. If you’re not sure how to get the latest firmware for your hardware, check with the device manufacturer.

14. Limit data shared between devices. Android and Windows devices let you choose the information you share between devices. So, for instance, you can choose to share phone audio, media audio, contacts and text messages with your car. If you don't need to share all of the data, deselecting one or more of the types of information may enable the devices to pair. 

For Android devices, go to Settings > Bluetooth and select the device. If there are options to select, they will appear. For Windows, go to Control Panel > Hardware and Sound > Devices and Printers and right click on the Bluetooth device in question. Then select the Services tab to choose which types of information to share.

15. Clear the Blutooth cache (Android only). Sometimes apps will interfere with Bluetooth operation and clearing the cache can solve the problem. Go Settings > Backup and restart > Reset network settings. 

Not all wireless devices use Bluetooth

Keep in mind that not all wireless devices use Bluetooth. Alternatives include the Wireless Gigabit specification, Wireless HD, ANT+, ZigBee, NFC as well as Wi-Fi Direct. These other technologies typically won’t work with your phone, tablet or PC without some kind of additional hardware.

We hope this guide has helped you with your Bluetooth pairing problems. If you know of any tip we've missed, share in the comments below!

Go figure

From Gil Gaudia on August 29, 2019 :: 6:18 pm

First I want to thank all who have tried to help me solve this annoying problem.  I tried every reasonable suggestion including those from Toyota and Xfinity (the phone provider).  I gave up and did not use my car phone for several days. Tuesday, on a whim, I tried it again and it worked flawlessly for about two dozen calls.  Wednesday, the same. Today it is still working perfectly. I wonder how long it will last?

We have a separate article on Onn headphones

From Josh Kirschner on September 06, 2019 :: 5:48 pm

The quick answer is probably “forgetting” the headphones on your phone and re-paring. Check out our article on How to Connect Onn Headphones to Bluetooth for detailed advice.

I already tried that

From Amy on September 06, 2019 :: 7:50 pm

I have tried this but the problem is that they have never connected to my phone and my phone doesn’t let me forget it since it was not connected in the first place. I have looked up multiple websites and watched a ton of videos but nothing is working. The last step I need to connect my phone is the pin, unless somehow you can tell me how I could possibly “forget” the earbuds bc I have no clue how to do that I tried that but my phone doesn’t let me. My phone is a Samsung Galaxy J7 Star.
Thanks!
Much appreciated!

The Citroen cam connects by Wi-Fi, not Bluetooth

From Josh Kirschner on September 06, 2019 :: 5:52 pm

The Citroen cam connects by Wi-Fi, not Bluetooth. However, when you set up the network for the cam, it won’t have internet access (you’re just setting up a private connection to the cam’s Wi-Fi network), but that’s okay. If you go to the Citroen app, you should be able to see if the two are connected correctly. If you’re still having issues, you can look at the detailed connection steps in the video here: https://www.citroen.co.uk/about-citroen/technology/connectedcam-citroen

Windows 10 Bluetooth woes.

From Jim Parr on October 11, 2019 :: 7:33 am

My H800 logitech headseat is the only bluetooth device I use with my old VAIO laptop workhorse.
It works fine but nearly always needs manual forcing to pair.
1) Switch on headset.  Waiting waiting waiting…
2) After a minute or so, open W10 Settings and click on Connect.  Waiting - usually for about 30 seconds - failure.
3) Click on Connect again and nearly always a solid connection within a second or so.

Just saying - this is OBVIOUS SOFTWARE B.S. There are many similar hooks and traps in W10 that can slow the machine to a near standstill.

None are consistent and none seem to be amenable to solutions.

Magnvox stereo pairs fine but....

From Elizabeth Clarkson on October 14, 2019 :: 1:36 pm

My Magnavox Mini stereo model mm435 pairs fine with my phone & my hearing aid which operates through a program in my iPhone. The problem is that this stereo has a “function” button and you press it once to put the stereo into discovery mode so it will pair with the Bluetooth oh, and it’s so so with no problem but then you have to hit the button a second or a third time in order to either listen to the radio or play a CD so press the function button comet it’s in pairing mode, it pairs fine easily no problem but now you want to listen to your CD and as soon as you click out of pairing mode and go to CD it unpairs! I have tried every Magnavox phone number imaginable and every number that they have given me and all they keep doing is referring you back to the manual or the website neither of which answers this question….HELP!

To use my Bose

From Marcel Rivest on October 28, 2019 :: 2:43 pm

To use my Bose headphone with my TV, I use a taotronics device that I plugged in the router (with the white and red cable).  The headphone works only on the left side.  I know that the headphone works on the right side with other devices.

Do you have a clue why this is happening.
Thanks

The router?

From Josh Kirschner on October 29, 2019 :: 4:24 pm

I’m confused by your setup. Do you mean you plugged it into your router or your cable box? Either way, the most logical way to connect the Taotronics transmitter would be to use the 3.5mm audio output jack directly from your TV into the transmitter, not to use the old RCA outputs from your cable box. That way you will get audio for all the material on your TV - cable and streaming - not just what comes through your cable box.

What model TV do you have?

From Josh Kirschner on November 01, 2019 :: 8:13 am

Are you sure there’s no output jack? I’m pretty sure every TV should have an audio out on it somewhere. What model Panasonic TV do you have?

Hi Josh.  My TV is a Panasonic Viera TC-P60ST50.

OK, that will be a little trickier

From Josh Kirschner on November 01, 2019 :: 12:06 pm

For whatever reason, Panasonic decided not to include a standard 3.5mm output jack on those Viera models. There is, however, an optical output that you can plug into your transmitter, but you will need an optical digital to 3.5mm converter to do it (they’re not very expensive).

But, here’s where it gets worse. From what I’ve read, Panasonic removed the ability to turn off the internal speakers in the audio menu (you can check to see if this is true). If you can’t turn them off, then you can’t listen to TV silently through your headphones.

So, that gets you back to where you were before, which is how to get sound in both ears from your cable box. It should work as you tried before, so you may want to reach out to your cable company for help (every cable set up is different, so it’s hard for me to provide specific advice). The cable box may also have an optical output you could try, instead. Also, have you confirmed that the Taoyronics device works with other devices? That is, plug it into a laptop with 3.5mm and see if it outputs to both ears? If not, the problem lies in the transmitter.
