How to disable bluetooth on r.pi?

I’m not using bluetooth. I want to disable it on the raspberry pi running APsync, since I don’t need yet another active radio on board.

I added dtoverlay=pi3-disable-bt to /boot/config.txt, which disabled bluetooth, but also must have reassigned serial device names since cmavlink then was unable to connect to /dev/ttyS0.

Does anyone know what needs to be changed to make this work? Thanks.

Disabling Bluetooth makes the mapping of UART1 back to UART0 so the device becomes /dev/ttyAMA0
