How to troubleshooting iPhone 7 Plus that won’t pair with other Bluetooth devices

Before you start to troubleshoot, make sure both your iPhone and Bluetooth device are within range, if not next to each other. For Bluetooth devices to communicate, they need to be within range, usually within a 100-meter distance from each other. To ensure that distance isn’t the issue, position your devices next to each other. If that doesn’t work, then try these simple solutions.

First solution: Reboot/soft reset your iPhone and Bluetooth device.

Minor software errors on the iPhone or Bluetooth device can cause conflict and may interfere with the Bluetooth connection. Such errors are usually transpiring after implementing new platform or system changes. And a simple solution you can try on first would be a soft reset on the iPhone and the Bluetooth device too. This will help clear minor software errors inflicted by the new recent update. If you haven’t yet done it, then follow these steps to soft reset or reboot your iPhone 7 Plus:

  1. Press and hold the Power button for a few seconds until the Slide to Power Off command appears.
  2. Then drag the power off slider to the right to shut down your iPhone completely.
  3. After 30 seconds, press the Power button again until the Apple logo appears.

Performing a soft reset doesn’t result to data loss as it won’t affect the internal data on your iPhone. After restarting your iPhone 7 Plus, get to your Bluetooth device, locate its power switch and then turn it off for a few seconds. After about 30 seconds, flip the power switch again to turn the device back on. Make sure it’s set to pairing mode or discoverable mode. Most devices have this pairing switch to toggle. If you don’t see it on your device, then just ensure it’s turned on and positioned near your iPhone.

Second solution: Turn Bluetooth off and then on again.

This is another old, simple trick that can help clear minor errors affecting your iPhone’s Bluetooth functions. Doing so allows your device to establish a fresh connection with its paired Bluetooth devices. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap Bluetooth.
  3. Toggle the Bluetooth switch to turn the feature off.
  4. After 30 seconds, tap the switch to turn Bluetooth back on.

You can also disable or enable Bluetooth on your iPhone 7 Plus through the Control Center. Simply launch the Control Center then toggle the Bluetooth icon off and then on again. This trick helps refresh Bluetooth connections on your iPhone.

Third solution: Forget/delete Bluetooth device on your iPhone 7 Plus.

The new update might have messed up with your iPhone’s Bluetooth connections. If this happens, you may need to set up Bluetooth connections on your iPhone again. To get this done, follow these steps to delete or forget Bluetooth devices from your iPhone and then retry pairing them:

  1. Tap to open the Settings app.
  2. Tap Bluetooth. A list of available Bluetooth devices will then show up on the screen.
  3. Tap the information “i” icon next to the Bluetooth device you want to forget or delete.
  4. Then select the option to Forget This Device.
  5. If prompted with a confirmation message, tap OK to continue.

Reboot your iPhone after deleting Bluetooth devices. Then put your Bluetooth device in pairing mode, search for available Bluetooth devices on your iPhone and then re-attempt pairing.

Fourth solution: Reset network settings on your iPhone 7 Plus.

The recent iOS transition might have caused complex network errors on the iPhone system and this could be the main reason why Bluetooth functions have failed. To clear this out, performing a network settings reset can help. Doing so will delete the current network settings on your iPhone 7 Plus and then restores the default or original values. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Reset Network Settings from the given options.
  5. If prompted, enter your passcode to continue.
  6. Then tap the option to confirm network settings reset.

Allow your device to finish resetting the network settings and then reboots by itself. Once it’s finished booting up, reconnect to your Wi-Fi network and enable Bluetooth on your iPhone. Once enabled, retry pairing your iPhone 7 Plus with your Bluetooth device and see if the problem is gone.

Fifth solution: Factory reset/master reset your iPhone 7 Plus.

A full system reset is usually the last option to consider if all else failed to fix software-related problems including Bluetooth errors on the phone. In fact, many complex software issues are dealt with by a factory reset or master reset. Just note though that this will also erase critical data including personal information you saved on your device. If you wish to give it a shot, back up all your important files and then follow these steps to factory reset your iPhone 7 Plus through settings menu:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select Erase all content and settings from the given options.
  5. If prompted, enter your passcode to continue.
  6. Then tap the option to confirm master reset.

Allow your device to finish resetting and restores the factory defaults. It will restart automatically as soon as the reset is finished. After it reboots, you can proceed with the initial setup process to configure options and enable features to use your iPhone again. Don’t forget to enable Bluetooth and reattempt pairing your iPhone 7 Plus with your Bluetooth device.

Other options

If none of the aforementioned solutions is able to solve the problem, then you could be dealing with a hardware issue either on your iPhone 7 Plus or Bluetooth device. At this point, you may have to consider taking a trip to an Apple Genius bar and ask an iPhone technician to run a thorough hardware check. If your iPhone is clear from any sort of hardware damage, then the problem could be on the Bluetooth device. You can contact the manufacturer of your Bluetooth device for further assistance in getting it to pair with and work with your iPhone 7 Plus.
