[PROBLEM] Bluetooth Audio output (Transmitter)

[Nachteule]

It looks to me like now the rpi bluetooth device is no longer initialized and thus present

Please delete the file /var/log/upstart/rpi-bluetooth.log, restart and then post the file here

It should look like this:

Code:

/dev/serial1 still not there, waiting ...
using /dev/serial1@3000000
bcm43xx_init
Set Controller UART speed to 3000000 bit/s
Flash firmware /etc/firmware/brcm/BCM4345C0.hcd
Set BDADDR UART: aa:bb:cc:dd:ee:ff
Set Controller UART speed to 3000000 bit/s
Device setup complete
BDADDR need not be set for hci0

This is the output from my 3B+

Furthermore I have with my different configurations that the bluetooth daemon (bluetoothd) is not started correctly by the script /etc/init/bluetooth.conf or bluetooth is not in power up mode

However, this does not always occur with me, but with the 3B+ under Debian Buster. With Debian Bullseye and 4B this is always ok

Anyway, I made a new script, you could also try this as a test

cat /etc/init/bluetooth.conf

Code:

description "bluetooth"
author      "mkreisl mkreisl@xbian.org"

start on (started rpi-bluetooth or started imx-bluetooth)
stop on runlevel [06]

env DAEMON=/usr/sbin/bluetoothd
env HCIATTACH=/usr/bin/hciattach

env HID2HCI_ENABLED=1
env HID2HCI_UNDO=1

env SDPTOOL=/usr/bin/sdptool

# If you want to be ignore error of "org.freedesktop.hostname1",
# please enable NOPLUGIN_OPTION.
# NOPLUGIN_OPTION="--noplugin=hostname"
env NOPLUGIN_OPTION=""

script
    [ -f /etc/default/bluetooth ] && . /etc/default/bluetooth
    [ -f /etc/default/rcS ] && . /etc/default/rcS

    [ "$BLUETOOTH_ENABLED" = 1 ] || { stop; exit 0; }

    SSD_OPTIONS="--oknodo --quiet --exec $DAEMON -- $NOPLUGIN_OPTION"
    start-stop-daemon --start $SSD_OPTIONS
end script

post-start script
    [ -f /etc/default/bluetooth ] && . /etc/default/bluetooth
    [ -f /etc/default/rcS ] && . /etc/default/rcS

    # FIXME: this function is possibly a no-op
    run_sdptool()
    {
        # declaring IFS local in this function, removes the need to
        # save/restore it
        local IFS o

        test -x $SDPTOOL || return 1

        # FIXME: where does SDPTOOL_OPTIONS come from?
        if ! test -z "$SDPTOOL_OPTIONS" ; then
            IFS=";"
            for o in $SDPTOOL_OPTIONS ; do
                #echo "execing $SDPTOOL $o"
                IFS=" "
                if [ "$VERBOSE" != no ]; then
                    $SDPTOOL $o
                else
                    $SDPTOOL $o >/dev/null 2>&1
                fi
            done
        fi
    }

    run_sdptool || :

    if test "$HID2HCI_ENABLED" = 1; then
        echo "switching to HID/HCI no longer done here, see /usr/share/doc/bluez/NEWS.Debian.gz" || :
    fi

    bluetoothctl power on
end script

post-stop script
    [ -f /etc/default/bluetooth ] && . /etc/default/bluetooth
    [ -f /etc/default/rcS ] && . /etc/default/rcS

    if test "$HID2HCI_UNDO" = 1; then
        echo "switching to HID/HCI no longer done here, see /usr/share/doc/bluez/NEWS.Debian.gz" || :
    fi

end script

With this new script you should see in the file /var/log/upstart/bluetooth.log the following

Code:

Changing power on succeeded
