Many thanks for all your inputs, guys.
I solved the problem!

Problem was: additionaly to enable_uart=1 (ttyS0 (mini UART device)), I had explicity ttyAMA0 console activated.

So I did following:
/boot/cmdline.txt removed
console=ttyAMA0,115200

/boot/config.txt set

enable_uart=1
dtoverlay=pi3-miniuart-bt

Now it works fine.
