the smartphone is a Bluetooth 4.0 one.
I did the same experiment with another Bluetooth 4.0 smartphone. Same result.

In the past, this was working. I was using a Bluetooth 4.0 USB dongle.
Today I use a Bluetooth 5.2 PCI card EDUP LOVE ep-9651GS (intel AX210).

Most likely this is an issue with bluez/the kernel, not Plasma. All Plasma does it tell bluez to connect to a given device, there isn't really any room to do something wrong there.
