Things to Do When iPhone Cannot Connect to Bluetooth
Bluetooth opens the gate of a new generation of "connectionless" devices which is the foundation for transformative wireless connectivity. Nowadays, mobile devices are able to connect to a Bluetooth device using radio waves instead of wires or cables. To some extent, it's as convenient as Wi-Fi, which allows mobile users to surf the internet, but there are still people worrying about the security with Bluetooth connection.
Note that iOS requires that the remote Bluetooth device supports an encrypted connection. When you establish a pairing record between your iOS device and a Bluetooth device, you are setting up encryption between the two devices.
However, there are quite a few complaints concerning Bluetooth recently along with the debut of iPhone 7 and iPhone 7 Plus mainly in terms of the following issues.
1. Fail to Connect to Bluetooth Speaker
2. Cannot Pair with Apple Watch
3. Unable to Get connected with Bluetooth Headset
4. Can't use Bluetooth with devices in car like hand-free kits
If you're running into one of the situations above, here are some fixes for you to try. Please feel free to proceed. Of course, all of the workarounds are free of charge.

Notes: Things to Do before Fixing the Problem
1. Ensure that the Bluetooth on iPhone is on. If not, go to "Settings" > "Bluetooth' and turn it on.
2. Ensure that iPhone and the Bluetooth device is not running out of battery life. If yes, please juice up.
3. Keep both iPhone and the Bluetooth device close to one another.
4. Don't get too close to a Wi-Fi router which might cause Bluetooth interference.

Method 1: Toggle on and off Bluetooth
Sometimes problem of this kind can easily be solved by simple steps like: Turn on and then off the feature. You can go to "Settings" > "Bluetooth" > and toggle on and off the bar.
Method 2: Enable Airplane Mode
When you turn on Airplane Mode, the network connection and Bluetooth will be shut down. This way is similar to Method 1, so please try to turn on and off Airplane Mode and see whether it helps.
Method 3: Soft or Hard Reboot your iOS Device
Otherwise, try to restart your iOS device, which can be much helpful in some cases. There are two reboots on iPhone, known as Soft Reboot and Hard Reboot. As for a Soft Reboot, please keep pressing the "Wake/Sleep" button and then swipe the "slide to power off" bar. As for a Hard Reboot, you need to hold down "Home" and "Wake/Sleep" buttons at the same time until the screen gets dark. Then, turn it on.
Method 4: Forget the Bluetooth Device
Another way to try is to forget the Bluetooth with which is unable to connect and then reconnect to it. Please go to "Settings" > "Bluetooth". There will be a list of Bluetooth devices under the title of "Devices". Please tap the button next to the target device and choose "Forget this device". After a while, try pairing your iPhone and the Bluetooth device again.
Method 5: Perform a Network Reset
It's possible that the Bluetooth problem is caused by a network issue, so try to reset the network settings in order to erase and reset network condition. You can get it done via "Settings" > "General" > "Reset" > "Reset Network Settings". After that, try again and see whether it works.
Method 6: Update Software via OTA or iTunes
Generally speaking, if the solutions are not working on your iPhone, this might be an unsolved bug in the present iOS, which is highly possible to be addressed in the latest version of iOS. Therefore, please go to "Settings" > "Software Update" and check whether a new update is available. If so, you can directly download and install it on iPhone, or use iTunes to upgrade your iPhone.
Method 7: Restore iPhone to Factory Reset
This step is the final risk you might consider taking. Most of the time, a variety of iOS problems can be solved via factory reset. Prior to it, you should make sure that you've done a full backup for content currently stored on iPhone. On iPhone, go to "Settings" > "General" > "Reset" > "Erase All Content and Settings".
Normally, it's easy to fix the Bluetooth problem if that's a software problem. However, if it's a hardware problem, there's nothing I can do to help you out. In this case, you must take your iPhone to Apple Store or any authorized store and have it repaired.
