I am struggling with connecting Bluetooth devices to my PI
Open a terminal window.
Use either vi or nano to edit /boot/config.txt
# See /boot/overlays/README for all available options
dtparam=audio=on
dtoverlay=vc4-kms-v3d
display_auto_detect=1
disable_overscan=1
initramfs initramfs-linux.img followkernel
#Uncomment - to - enable - bluetooth
#dtparam=krnbt=on
[pi4]
# Run as fast as firmware / board allows
arm_boost=1
Find
#Uncomment - to - enable - bluetooth
#dtparam=krnbt=on
uncomment #dtparam=krnbt=on by removing the leading #
reboot and try again.
