First, let’s start with “What is Bluetooth?”

Bluetooth is a wireless communication standard. Compatible devices can exchange data without connecting cables. The valid range is about 10m. Because it is an international standard, any compatible device can be connected by any manufacturer in each country.

Bluetooth mark
A person who says, “I can’t get right to the point …” may be more natural to understand if you listen to the examples. For example, imagine a Bluetooth earphone.

Until now, earphones were designed to insert the end of a cable into a smartphone or PC. However, if you connect a Bluetooth-compatible headset to your smartphone, you don’t need a rope. To wirelessly transmit music data from smartphones to earphones, Bluetooth earphones can also be used in independent shapes like earplugs.

It is necessary to check whether there is any problem with the smartphone or car audio used. Still, it can be solved by ” clearing the cache” (for Android) with the smartphone or “deleting device information” on the setting screen In some cases.

In some cases, the file cached by the device OS update may be damaged, and the Bluetooth connection may not be appropriately established.

* Playing and stopping, power and volume are nothing, but you may start pairing by pressing and holding a relevant button.

3. Priority output for Bluetooth earphones

This is because the speaker you have been using has priority over Bluetooth as the output destination.

Go to “Control Panel”-> “Sound,” right-click the icon that says “Bluetooth Audio Device,” and try “Set as Default Device.”
