What you need before you start
Before you connect a Bluetooth device, make sure both the device and the phone or computer you're connecting to have Bluetooth turned on. Most phones and computers have a Bluetooth toggle in their settings or quick-access menu. The device you're connecting — whether it's a speaker, headphones, keyboard, or mouse — should also be in pairing mode, which usually means holding down a button for a few seconds until a light blinks or you hear a tone.
Check that your device is charged or has fresh batteries. A low battery can prevent pairing from working. Also, keep the two devices within about 30 feet of each other during the pairing process, though most work best within 10 feet.
Key Takeaways
- Turn on Bluetooth on both devices and put the device you're connecting into pairing mode, usually by holding a button until a light blinks.
- On your phone or computer, open Bluetooth settings and look for the device name in the list of available devices.
- Select the device name and confirm the pairing when prompted — some devices require you to enter a PIN or confirm a code on both sides.
- Once paired, the device will usually reconnect automatically the next time you turn on Bluetooth and bring the devices close together.
Connecting on iPhone or iPad
Open Settings and tap Bluetooth. Make sure the toggle at the top is turned on — it will show blue when active. Your phone will then scan for nearby devices in pairing mode. When you see your device's name appear in the list under "Other Devices," tap it.
If the device asks for a PIN, you'll see a prompt on your screen. Most common devices use 0000 or 1234, but check your device's manual if neither works. Once you tap the device name and confirm any PIN, it will move to the "My Devices" section at the top of the Bluetooth settings screen. This means it's paired and ready to use.
Connecting on Android phones
Open Settings and look for Bluetooth — on most Android phones this is under "Connected devices" or "Connections." Turn Bluetooth on if it's not already active. Your phone will show a list of available devices. Find your device in the list and tap it.
Android may ask you to confirm the pairing or enter a PIN. Once you do, the device will appear in your list of paired devices. If you don't see your device in the list, make sure it's in pairing mode and try tapping "Scan" or "Search for devices" again.
Connecting on Windows computers
Click the Windows Start button and open Settings. Go to Bluetooth & devices, then make sure Bluetooth is turned on. Click "Add device" and select Bluetooth from the menu that appears. Windows will scan for nearby devices in pairing mode.
When you see your device in the list, click it. Windows may ask you to confirm a PIN or code — if so, you'll see the same code on both your computer and the device. Click "Yes" or "Connect" to finish pairing. The device will now appear in your paired devices list.
Connecting on Mac computers
Click the Apple menu and open System Settings. Go to Bluetooth and make sure it's turned on. Your Mac will automatically scan for nearby devices in pairing mode. When you see your device's name, click it.
If prompted, enter the PIN shown on your screen or confirm the pairing code on both devices. Once paired, the device will show as "Connected" in the Bluetooth settings. On future uses, your Mac will reconnect automatically when the device is nearby and Bluetooth is on.
What to do if pairing fails
If a device won't appear in your scan, make sure it's actually in pairing mode. Some devices only stay in pairing mode for 30 seconds, so you may need to hold the button again. Also check that Bluetooth is turned on on both sides — it's easy to miss.
If the device appears but won't connect, try "forgetting" it and pairing again. On iPhone or iPad, tap the info icon next to the device name and select "Forget This Device." On Android, long-press the device name and choose "Unpair." On Windows or Mac, right-click the device and select "Remove" or "Delete." Then put the device back in pairing mode and try again from the beginning.
If you're still stuck, restart both devices completely — turn them off and back on — and try pairing once more. Restart often clears temporary connection problems that prevent pairing from working.
Reconnecting a device you've already paired
Once you've paired a device once, you don't have to pair it again. The next time you turn on Bluetooth on both your phone or computer and the device itself, they should reconnect automatically within a few seconds. You'll usually see a notification or hear a tone when the connection is made.
If a device doesn't reconnect automatically, make sure Bluetooth is turned on on both sides and the devices are close together. If it still won't connect, try turning Bluetooth off and back on, or restart the device itself. Most of the time, one of these steps will bring the connection back.
Frequently Asked Questions
Why can't I see my device in the Bluetooth list?
The device is probably not in pairing mode. Look for a button on the device and hold it for three to five seconds until you see a blinking light or hear a tone. Some devices have a dedicated pairing button; others use the power button. Check your device's manual if you're not sure which button to press.
Do I have to pair my device every time I use it?
No. Once you pair a device, it stays paired. The next time you turn on Bluetooth on both your phone or computer and the device, they reconnect automatically. You only pair once, unless you unpair the device on purpose or reset it to factory settings.
What does the PIN or code mean when I'm pairing?
The PIN or code confirms that you're connecting to the right device and not someone else's. Both devices show the same code to prove they're talking to each other. You just need to confirm it matches on both sides — you don't have to remember or type it in most cases.
Can I connect one device to multiple phones or computers?
Yes. You can pair a Bluetooth speaker, headphones, or keyboard to your phone, tablet, and computer all at once. However, most devices can only play audio or receive input from one device at a time. When you want to switch, you usually just disconnect from one and connect to the other through that device's Bluetooth settings.
Why does my device keep disconnecting?
Bluetooth connections drop when devices move too far apart, when Bluetooth is turned off, or when the battery is very low. Keep your devices within 30 feet of each other and make sure both have enough power. If disconnections happen often, try restarting both devices or moving closer to rule out range or interference issues.
