Hi. Here is my setup:

dinth@ebusd:/dev $ uname -a
Linux ebusd 5.15.84-v7+ #1613 SMP Thu Jan 5 11:59:48 GMT 2023 armv7l GNU/Linux
dinth@ebusd:/dev $ cat /sys/firmware/devicetree/base/model
Raspberry Pi 3 Model B Rev 1.2dinth@ebusd:/dev $ ^C
dinth@ebusd:/dev $

I followed the instructions from the documentation:

Added dtoverlay=miniuart-bt to config.txt (i have also tried dtoverlay=pi3-miniuart-bt)
Disabled login shell and serial port hardware in raspi-config.
Also tried removing enable_uart=0 from config.txt

But /dev/ttyAMA0 is still there.
Any advice?
