We need to enable bluetooth and dbus on our rapi4 x64 image. I can't find any documentation on doing this. We're new to yocto and RDK. Can someone please help?

source: rdkb-2023q4-kirkstone

manifest: rdkb-extsrc.xml

build:

export MACHINE=raspberrypi4-64-rdk-broadband

source ./meta-cmf-raspberrypi/setup-environment

bitbake rdk-generic-broadband-image

Mar 21 2024 update:

To get dbus on and enabled, we removed the lines 17-20 from meta-cmf-raspberrypi/recipes-core/dbus/dbus_%.bbappend:

do_install_append_aarch64_broadband () {
          # Removing dbus service in 64bit arch alone
          rm  ${D}${systemd_system_unitdir}/dbus.service   
}

However even though it appears the rpi Bluetooth stack is compiled, it appears to be non functional as we’re getting an init failure from hci uart (particularly a timeout).
Any suggestions Unknown User (manigandanj)? (since you were the last to update the rapi4 document)

    Hello Unknown User (ryanhagen) ,

    dbus is part of your requirement? we are moving towards rbus.

    timeout may be in fetching. let us try and come back on this.

    Hello Unknown User (ryanhagen) ,

    we could generate build (imagename:rdkb-generic-broadband-image_rdkb-2023q4-kirkstone_20240326120151) with dbus as you mentioned. 

    Observing this failure.
