Hi everyone, I'm writing some scripts to automate fixing some issues with PulseAudio, Bluetooth, and A2DP. I've found some useful examples online, and I have a script that works when I run it manually. However, when udev kicks off the rule, I get the error in $subject, which I imagine means that bluetoothctl can't connect to bluetoothd. I also tried using hcitool, but that doesn't fix my bluetooth issues. I tried looking at the code for bluetoothctl, and it seems like it's using dbus in the background. If that's the case, I would think that setting XDG_RUNTIME_DIR, XAUTHORITY and DISPLAY should be enough. I originally posted the question here: https://superuser.com/questions/ 1245940/bluetoothctl-waiting-to-connect-to-bluetoothd-in-udev-rule- script Here are the scripts I have, which I believe should work with any bluetooth headset as long as there's only 1 pulseaudio instance running and only 1 headset connected: /etc/udev/rules.d/80-bt-headset.rules ------------------------------------------------- ACTION=="add", SUBSYSTEM=="bluetooth", RUN+="/usr/local/bin/a2dp-fix- wrapper" ------------------------------------------------- /usr/local/bin/a2dp-fix-wrapper ------------------------------------------------- #!/bin/bash -x PID=$(pgrep pulseaudio) USER=$(grep -z USER= /proc/$PID/environ | sed 's/.*=//') USER_ID=$(id -u $USER) HOME=$(echo $(getent passwd $USER )| cut -d : -f 6) export XDG_RUNTIME_DIR=/run/user/$USER_ID export XAUTHORITY=$HOME/.Xauthority export DISPLAY=:0 export PULSE_RUNTIME_PATH=$XDG_RUNTIME_DIR/pulse/ sleep 5 sudo -u $USER -E /usr/local/bin/a2dp-fix &> /udev_output.txt ------------------------------------------------- /usr/local/bin/a2dp-fix ------------------------------------------------- #!/bin/bash -x bt_device_addr=$(pacmd list-cards | grep -i 'name:.*bluez_card' | sed -E 's/.*<?bluez_card\.([A-Z0-9_]+)>?/\1/') device_mac=$(echo $bt_device_addr | sed 's/_/:/g') a2dp_available=$(pacmd list-cards | grep -A30 bluez | grep "A2DP Sink" | sed -E 's/.* available: ([a-z]+)\)/\1/g') if [[ "$a2dp_available" == "no" ]] then echo -e "connect $device_mac\nquit" | bluetoothctl sleep 5 pacmd set-card-profile bluez_card.$bt_device_addr off pacmd set-card-profile bluez_card.$bt_device_addr a2dp_sink pacmd set-default-sink bluez_sink.$bt_device_addr.a2dp_sink fi ------------------------------------------------- The following things work: * running `/usr/local/bin/a2dp-fix` as current user * running `sudo /usr/local/bin/a2dp-fix-wrapper` Any help would be greatly appreciated! -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
