The emergence of Bluetooth receivers has made many old-fashioned audio equipment have Bluetooth function, we use the mobile phone to connect to the Bluetooth adapter at the same time, we may encounter unsuccessful pairing, especially iPhone users, after canceling the pairing, it has not been connected, what is the reason? Today, the engineer will give you a list of common problems and solutions for unsuccessful Bluetooth pairing, and the operation is very simple.

Question 1: The pairing between the mobile phone and the Bluetooth receiver is unsuccessful for the first time?

In this case, please confirm that the Bluetooth receiver is powered on and that the Bluetooth name matched by the phone is the Bluetooth device. Take the green Bluetooth receiver as an example, the blue indicator will light up when the device is turned on, and the default device name is: ugreen-40759e, and the phone can be paired by clicking on the connection after this name appears.

Question 2: I cancel the pairing after successful pairing, and I can't connect to it next time?

The reason is that after unpairing, the Bluetooth device name will appear on the phone's searchable bar, but it is just a cache record, refresh it and it will be gone, if you click on pairing, it will not be connected, and even turn off the phone's Bluetooth and turn it on again, you will not be able to connect to the device.

Solution: Restart the Bluetooth receiver, and then restart the Bluetooth of the phone to pair. As shown in the figure below, after unpairing, ugreen-40759e appears in the available devices, but it cannot be matched, double click the multi-function button of the green Bluetooth receiver to complete the restart, turn off and then turn on the Bluetooth of the mobile phone to complete the pairing connection.

It is because the Bluetooth receiver will be reconnected to the last paired device first, and then automatically connected, so other devices cannot be connected.

Solution: Turn off the Bluetooth of the mobile phone that was successfully matched before, and then other mobile phones and tablets can be matched. If you can't find the currently matched phone or can't turn off Bluetooth after being successfully paired with someone else's phone, you need to restart the Bluetooth receiver to forcibly disconnect, and then match.

Note: Some Greenlink Bluetooth receivers have the function of connecting two mobile phones at the same time. ）

Question 4: Usually the match is normal, but suddenly it can't be connected?

This situation mostly occurs in iPhones, which may be caused by the failure of the previous matching information after the Bluetooth receiver has been factory reset.
