I keep having problems with what seems like someone else like my neighbor is pairing with my Soundcore. I think they may have a soundcore as well? Well now I cant play the white noise at night for my son because someone else is connected to my device. How can I prevent this? Is there a way to change the name of the device in Bluetooth? Or a way to prevent someone else to pair with my device?
I guess your referring to a Soundcore Wakey or are you talking about a different model? Depending on location of your speaker the neighbour might just be in range to have accidentally connect when you were in initial pairing mode.
If you press and hold the BT or the volume +/- buttons for 3-5 seconds this often forces the BT pairing records to clear, complete a fresh pairing afterwards and see how things go.
