With each update and release of a new version of iOS, users increasingly have a problem when they are unable to pair their iPhone with a wireless speaker, headset, or connect to a car system. This situation occurs especially often among users running iOS 7 and older versions. Even installing patches does not always solve this problem.
Need to figure it out Why doesn't bluetooth work on iPhone?. There may be several reasons, but if the smartphone has not been dropped, has no mechanical damage, or has not been filled with liquid, then this is definitely a software problem. If the Bluetooth module itself fails, it is strongly recommended not to disassemble the unit yourself. It is better to take it to the service center and give it to specialists.
Many people are interested what is bluetooth on iphone, and why the connection periodically disappears. On the forums you can find explanations that low-quality modules are installed, but in reality this is not the case. Apple's policy is that they impose restrictions on working with some headsets and generally prohibit file transfer via Bluetooth. Headsets manufactured only by Apple are guaranteed to work. It is also impossible to connect two phones simultaneously via Bluetooth using standard means. Bypassing the restrictions is possible by jailbacking your smartphone.
Preliminary actions
Let's look at several methods that can help solve the problem with Bluetooth not working. These steps must be done first.
First of all, make sure that the batteries of the paired devices are fully charged, and that the phone and gadget are in close proximity to each other. It is also advisable to restart the accessory and remember to turn it on. If possible, it is advisable to contact the support service of the accessory manufacturer to make sure that iOS support is implemented and tested, and that the latest version of the operating system should be installed on the phone.
Reboot your phone
The very first and most logical way is to hot reboot the iPhone. To do this you need:
- Go to the configuration menu and in the Bluetooth section disable the radio module.
- Simultaneously hold down two buttons - “Power” and “Home”, and wait for the iPhone to restart.
- After turning it on, activate Bluetooth back and try to search again.
There is a very high probability that performance will be restored. If this does not happen, then you need to move on to the next step.
“Forget” the problematic device
If you have already paired with this device before, but then something went wrong, then you can try to “forget” the device with which the problem occurs, i.e. the device will be removed from the system and system files will be cleaned. This is done as follows:
- All saved devices are located in the Bluetooth section of the Settings menu.
- From the list, select the gadget that has stopped connecting and click on the “i” icon.
- In the context menu, select the “Forget this device” option.
- After confirming the action, you need to re-search and configure the connection.
System reset and subsequent recovery
If the previous steps did not help, you can reset the settings and restore the default values. To do this, go to the configuration menu and select “Reset” in the “Basic” section.
Next, the iPhone will display a list of settings that can be reset. Here you select the “Reset network settings” option. The configuration will be updated and the device will reboot automatically. Instead of resetting network settings, you can select “Reset all settings”, but it is advisable to back up the data on your iPhone in advance. After a complete reset, the system is restored from a previously made copy through iTunes.
If none of the above methods helped solve the problem, and there is still no connection via Bluetooth, then most likely it is the module that has failed and you will have to take the iPhone to a certified service center for diagnostics and subsequent repairs.
