Some days ago I've found my old Raspberry Pi3+ and decided to play a little bit with it. First step was to flash to the SD card newest Kali. I've did it with balena Etcher flasher and it booted like a charm.
After a while I've realized that bluetooth is not working. Nothing was found:(
I've enabled bluetooth service and hciuaart:
modprobe btusb # add the btusb module to the kernel
systemctl enable bluetooth.service
systemctl enable hciuart
But still nothing...
But then I've checked /boot/config.txt and edited lines in the following way:
# Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=off
#dtparam=i2s=on
dtparam=spi=off
dtoverlay=miniuart-bt
And now it is working.
For Pi4 use
dtoverlay=pi4-enable-bt
