If your iPhone does not see another iPhone via Bluetooth, and you don’t know why. In this article we will tell you what to do in this situation. Bluetooth is a wireless technology that connects your iPhone to BlueTooth devices, such as another iPhone, headphones, keyboards, or even your car.
There are quite a few reasons why BlueTooth may refuse to work with an iPhone. And in this article, we will guide you step by step through the process of solving such problems. We'll explain why your iPhone won't connect to BlueTooth and tell you how to fix this problem.
There are a few things we recommend you do before your phone starts pairing with your BlueTooth device. First, make sure BlueTooth is turned on by swiping from the top to the bottom of the screen. The control center will open, then click on the BlueTooth icon. BlueTooth is turned on when the button lights up blue.
Secondly, you must make sure that the device you want to connect to is within BlueTooth range of your iPhone. Unlike WiFi devices, which can be connected to from anywhere, the operating range of BlueTooth is usually limited to 10 meters. It is advisable to place the phone and device close to each other in order to avoid problems related to the BlueTooth range on your smartphone.
If your iPhone does not see another iPhone via Bluetooth and cannot connect to a BlueTooth device, try using another smartphone. If the connection also fails, most likely the problem lies not in the iPhone, but in a non-working BlueTooth device.
How to fix iPhone does not see another iPhone via Bluetooth or device?
If your smartphone still can't connect to BlueTooth, you'll need to dive a little deeper to troubleshoot the issue. First of all, we need to find out what exactly caused the problem: the software or hardware of the phone.
Let's check the hardware first: Your iPhone has an antenna that makes the BlueTooth connection. The same antenna is also responsible for connecting to WiFi, so if, in addition to the problem with BlueTooth, you simultaneously encounter a problem connecting to WiFi. There may be a problem with the hardware of your phone, but do not despair, we are still trying to deal with this problem.
Follow our instructions step by step so we can figure out why an iPhone can't see another iPhone over Bluetooth.
Turn your iPhone on and off
First, press and hold the Power button to turn off your phone. In the slider that appears, select Power Off. Wait about 30 seconds and make sure your iPhone is completely turned off.
To power on your smartphone, press and hold the power button again until you see the Apple logo. After your iPhone restarts, try connecting to BlueTooth again. If everything remains the same, follow the steps below.
Turn BlueTooth on and off
Restarting BlueTooth can sometimes help resolve minor software issues that may be causing your BlueTooth connection to not work. There are 3 ways to restart BlueTooth on iPhone:
Turn off BlueTooth in Settings
Step 1: Open Settings.
Step 2. Click “Bluetooth”.
Step 3: Turn off BlueTooth, you will know it is turned off when the button is grayed out.

Click on the WiFi icon and turn it off. Click on it again to turn it on. If this doesn't work, turn off WiFi and try using BlueTooth again.
If turning WiFi on and off did not solve the problem, do the same operation with Airplane mode through the control center.
Make your phone forget the BlueTooth device
When your phone forgets a BlueTooth device, it feels like it was never connected to that device. The next time you connect, the process will occur as if these devices were connected for the first time. To make your phone forget the BlueTooth device:
Step 1: Open Settings.
Step 2. Click “BlueTooth” .
Step 3. Click the blue “i” next to the BlueTooth device you want to connect.
Step 4: Click “Forget this device” .

Step 6. You will know that the device has been forgotten when it stops appearing under the “My Devices” tab in “Settings” -> Bluetooth.
Once your phone has forgotten the BlueTooth device, connect it to your iPhone. If you were able to connect the device, then the problem is solved. If you still have connection problems, we will move on to reinstalling the software.
Reboot your network settings
When you reset your network settings, your iPhone's data on all BlueTooth devices, WiFi and VPN (Virtual Private Network) networks will be erased. Resetting the settings may solve some BlueTooth connection problems.
Before resetting your network settings, make sure you know your WiFi password as you will have to reconnect to WFi networks.
1. Open "Settings".
2. Click “Basic”. 
3. Click “Reset.”(Reset is the last option in Settings->General). 
4. Click “ Reset network settings“.
5. When prompted, enter your password on the screen.

7. When your iPhone turns on again, the network settings will be reset.
After resetting the network settings, try connecting to the BlueTooth device again. Remember that all BlueTooth data has been erased from your iPhone, so you will have to connect as if you were connecting to this device for the first time.
If all else fails, update iOS on your iPhone.
Most often, the problem of an iPhone not seeing another iPhone via Bluetooth can be solved by updating the OS. Read more about that. If you have a problem with your iPhone not seeing the iOS update, see this problem.
Use the best BlueTooth alternative – SHAREit
If the problem of an iPhone not seeing another iPhone via Bluetooth has not been resolved, and you need to transfer data to another iPhone, then you can use an alternative that is many times faster than “SHAREit”.
SHAREit is one of the best apps to transfer files faster than WiFi without any network connection.
How to use SHAREit to transfer files?
In this tutorial, I have given an example of transferring files between my Android phone and Windows PC. The same procedure can be followed when transferring files for any devices such as Android, iPhone, Windows iPhone, etc.
Requirements:
- Devices designed to transfer files must have WiFi functionality. [WiFi only, no network connection required].
- To start transferring files between one device to another, all you need is the SHAREit app installed on both devices. You can also download SHAREit app for PC to transfer data.
How to transfer files:
1. Open the app on your Android device and select "Send" and then click "Allow now".
2. Now select the files you want to transfer. Once you have selected the files, click "Further".
3. The app will now search for the nearest SHAREit device [anything other than your device]. 
4. Open the SHAREit app on your second smartphone or PC and click "Get".
5. Now your phone app will show the nearest device. Click on the device from your phone to make it start sending files to your computer.
You can do the same to transfer files from PC to your smartphone.

Almost every BlueTooth device has a switch or button that turns on pairing mode. Press and hold this button to turn off pairing mode. 
Wait about 30 seconds, then press the button or slide the switch again to turn on the device. Try connecting it to your iPhone again.

How does Bluetooth work on iPhone?
Let's be brief. iPhone cannot transfer files via Bluetooth. This was done to protect copyright. So that users could not share songs of famous authors and groups. Unfortunately, you will not be able to connect to another device and transfer something to each other.
Why then Bluetooth in iPhone?
Using Bluetooth, you can connect special headphones for listening to music, a headset for conversations and other modern gadgets to expand the functionality of the device.
How to transfer files to iPhone?

It's no secret to users of modern gadgets that bluetooth is a damn useful feature. With it, you can exchange different files, as well as connect many accessories and devices. And all this without annoying wires that you constantly have to untangle! However, on an iPhone with original firmware, bluetooth can only be used in the second way. The restriction on how to use Bluetooth on an iPhone is due to Apple's security policy, which seeks to prevent copyright infringement.
How to set up a Bluetooth connection
Let us recall that the bluetooth protocol began to be supported in Apple smartphones starting with the iOS 3.1 operating system, and in the first generation iPad - from the very beginning, with version 3.2. Bluetooth in the iPhone is used for wireless pairing with various devices, both native and third-party. These include keyboards, headphones, headsets, speakers, and even car stereos. Before purchasing and using a Bluetooth device, you should find out if your iPhone model supports its Bluetooth profile.
Here I will write in detail about how to connect a Bluetooth device to an iPhone and show it in screenshots of the 5s model with iOS 9.2.1:
- Wait for bluetooth to detect the device and display its name. Click on the name you need.
- Enter your passkey (PIN) if prompted. It must be specified in the documentation of the manufacturer of the connected device.
- Wait until the “Connected” status appears to the right of the accessory name.
That's all: now feel free to start using your device for its intended purpose. Additionally, you can pair your iPhone with more Bluetooth accessories by following the steps above.
Connection Status
You can check the connection status of your device to your iPhone by the color of the Bluetooth icon in the upper right corner of the status bar, as shown in the screenshot: podkluchenie ustroistva:
- black - bluetooth is turned on and the accessory is connected to your smartphone;
- gray - bluetooth is activated, but no accessory is connected;
- there is no icon - bluetooth is turned off or the iPhone is not paired with any device.
To disconnect all unnecessary devices, go to “Settings” → “Bluetooth”, to the right of the device name, click on the button with the “!” icon, then select “Disconnect”.
If you never plan to connect a Bluetooth accessory again (for example, you sold it or gave it to a friend), you should “unpair” or unpair. To do this, go to the same screen as when you disconnected the device, but click “Forget This Device.” Next, confirm your action by tapping the “Forget Device” button.
Now wait until you return to the previous screen - you will see that the forgotten device is no longer displayed in the “MY DEVICES” list.
