What if Apple's Bluetooth phone can't find the device?

Generally speaking, it is caused by unstable signal reception, which can be solved by turning off and turning on the Bluetooth switch several times. Or restart the Bluetooth device at the other end, and judge whether the status of the Bluetooth device is "Allow other devices to search". In the process of searching, the instrument should not leave the range, but should be within the communication range.

If the above methods can't be solved, it means that there is something wrong with the Bluetooth device, and you can go to the after-sales service department for repair.

The name of Bluetooth comes from:

The name of Bluetooth originated from Danish King Halad Branden. Because he likes blueberries very much, his teeth are blue every day. In the preparatory stage of this industrial association, this high-tech name must have a very representative name. After discussing the history of Europe and the development prospect of infinite technology overnight, some people think that it is most appropriate to name it after King Brandon.

King Brandon unified Norway, Sweden and Denmark. Brandon is eloquent and sociable. Just like technology, technology can cooperate in various industries and maintain good communication in industries such as computers, mobile phones and automobiles. In this way, Bluetooth is solved.
