I wanted to go out today and listen to music with my friends. At home, however, I noticed that my music box is not displayed even though Bluetooth is on. Do you know what you can do there? Incidentally, I have a huawei mate 20 lite and a small blue speaker from Sony.

so

Switch off the smartphone and start the Bluetooth search again,

some speakers also have a button for coupling

I've already tried

so

Seems to be some kind of illness

my speaker from JVC decouples and it takes forever until it funzt again
