Unified Remote: Bluetooth: Could not connect to SDP

You need to run the bluetooth daemon in compatibility mode to provide deprecated command line interfaces. You're running Bluez5 and you need some Bluez4 functions. You can do this by editing this file

/etc/systemd/system/dbus-org.bluez.service and changing this line

ExecStart=/usr/lib/bluetooth/bluetoothd to this

ExecStart=/usr/lib/bluetooth/bluetoothd --compat

and then restarting bluetooth like this

sudo systemctl daemon-reload
sudo systemctl restart bluetooth

and you'll also have to change permissions on /var/run/sdp

sudo chmod 777 /var/run/sdp

and finally restart unified remote server

Another solution:

Edit /etc/systemd/system/dbus-org.bluez.service:

ExecStart=/usr/lib/bluetooth/bluetoothd --compat
ExecStartPost=/bin/chmod 777 /var/run/sdp

Because permissions of /var/run/sdp seems to reset on every reboot.
