“Connection Establishment Error” with Bluetooth is one of the many Windows 10 errors that can interfere with computer users. The operating system sends this error message when a particular device can not be connected to the PC via Bluetooth or can not transfer the data. There are several reasons for this Windows error. Sometimes the problem is temporary and after a few attempts to pair devices, you can succeed. However, if you run out of patience or tried to do more than necessary, you should find this article handy. In this text, all possible methods to resolve the “Connection Establishment Error” error will be revealed.
Troubleshoot Bluetooth Connection Problems
- Make sure both devices are turned on
Just about any synchronization will fail if any of the devices are turned off. This seems like an obvious step, but between power-saving modes and sleep modes, a device that needs to be turned on can actually be turned off. Make sure everything is turned on and ready to be connected, and not locked in standby or in power saving mode.
- Make sure both devices have and support Bluetooth
Start with the basics: Make sure both devices you want to use have and support Bluetooth technology. It’s not because a headset is wireless or a stereo is new that Bluetooth is integrated. Look for the Bluetooth logo: a stylized B in an oval. Make sure it is on both devices you are trying to connect.
- Make sure your devices are compatible with each other
Now that we know that both devices have Bluetooth technology, we need to check and make sure both support the same version of Bluetooth. Bluetooth is supposed to be compatible with earlier versions, so an older headset needs to work with something like a new phone. However, there is also a newer protocol called Bluetooth Smart that works with items such as fitness bands. Bluetooth Smart may not be synchronized with older devices. Check your manuals or device information screens and make sure both devices support the same protocols.
- Check the manufacturer’s websites
Sometimes manufacturers know of a problem and publish a workaround or fix on their website. If you have problems with your Bluetooth devices, check each company’s web page for known problems, solutions, or ways to resolve them in the Technical Support section.
- Make sure Bluetooth is enabled on both devices
Turning off Bluetooth will save you energy and prevent many people from turning it off if they do not sync their phone with their car or do not work in hands-free mode. Check the settings of both devices and make sure Bluetooth is enabled and ready to connect. Make sure the devices use the same profile. Bluetooth devices use several different protocols to communicate. A mouse can have a profile called “Human Interface Device” because it is intended for one person, while a camera has a totally different profile. Incompatible profiles can cause connection errors. Check and make sure both devices speak the same language.
- Restart both devices just to be sure
This is the moment of magic words. Have you tried restarting? OK, this is the worst part of any support call, but the restart clears many errors and problems. It gives you and your devices a new blank canvas to synchronize.
- Make sure both devices are fully charged
Bluetooth uses radio frequencies to broadcast information, which means that the signal must be powerful enough. A weak battery or a phone with a loss of charge may not have the electrical power needed to make sure the signals go where they need to go. Check and make sure everything is loaded.
- Make sure airplane / energy saving modes are off
Airplane mode and power saving mode may disable some of the functions of the aircraft. Airplane mode will stop broadcasting parts including radio frequencies, including Bluetooth. The power saving features can turn off various things on your device, including Bluetooth. It’s easy to ignore, but it can also prevent your devices from working.
