Unified Remote: Bluetooth: Could not connect to SDP​

Main problem is the version of BlueZ.

sudo dnf install bluez-tools
# check package version
dnf list --installed | grep bluez

# list services
systemctl --no-pager | grep blue
systemctl status bluetooth.service
cat /usr/lib/systemd/system/bluetooth.service

# change this line:
# ExecStart=/usr/libexec/bluetooth/bluetoothd
# into
# ExecStart=/usr/libexec/bluetooth/bluetoothd -C

sudo systemctl daemon-reload
sudo systemctl start bluetooth

# try
sudo chmod 777 /var/run/sdp
sudo sdptool browse local
