SAP error on bluetooth service status

SAP stands for SIM Access Profile, so you have to disable it:

Open /etc/systemd/system/bluetooth.target.wants/bluetooth.service
Change:

ExecStart=/usr/lib/bluetooth/bluetoothd
To

ExecStart=/usr/lib/bluetooth/bluetoothd –noplugin=sap
Reload the systemd:

$ sudo systemctl daemon-reload
Restart the bluetooth:

$ sudo service bluetooth restart
Get the bluetooth status:

$ sudo service bluetooth status

bluetooth.service – Bluetooth service
