Well I had the problem that bluetooth was always off. I go to configuration->Bluetooth and every time I tried to put it on just returns to off a while after. I tried with this command:aptitude install bluetoothand then run/etc/init.d/bluetooth startafter that I runed /etc/init.d/bluetooth status and this is what shows: bluetooth.service - Bluetooth service   Loaded: loaded (/lib/systemd/system/bluetooth.service; disabled; vendor preset: disabled)   Active: active (running) since Tue 2017-01-17 21:13:47 UTC; 29s ago     Docs: man:bluetoothd(8) Main PID: 7939 (bluetoothd)   Status: Running    Tasks: 1 (limit: 4915)   CGroup: /system.slice/bluetooth.service           7939 /usr/lib/bluetooth/bluetoothdJan 17 21:13:47 kali bluetoothd[7939]: Error adding Link Loss serviceJan 17 21:13:47 kali bluetoothd[7939]: Not enough free handles to register ...ceJan 17 21:13:47 kali bluetoothd[7939]: Not enough free handles to register ...ceJan 17 21:13:47 kali bluetoothd[7939]: Not enough free handles to register ...ceJan 17 21:13:47 kali bluetoothd[7939]: Current Time Service could not be re...edJan 17 21:13:47 kali bluetoothd[7939]: gatt-time-server: Input/output error (5)Jan 17 21:13:47 kali bluetoothd[7939]: Not enough free handles to register ...ceJan 17 21:13:47 kali bluetoothd[7939]: Not enough free handles to register ...ceJan 17 21:13:47 kali bluetoothd[7939]: Sap driver initialization failed.Jan 17 21:13:47 kali bluetoothd[7939]: sap-server: Operation not permitted (1)Hint: Some lines were ellipsized, use -l to show in full.My computer is a sony VAIO SVF15A17CLV.Output from rfkill list all0: sony-wifi: Wireless LAN    Soft blocked: no    Hard blocked: no1: sony-bluetooth: Bluetooth    Soft blocked: no    Hard blocked: no2: phy0: Wireless LAN    Soft blocked: no    Hard blocked: no3: hci0: Bluetooth    Soft blocked: no    Hard blocked: noThank you!!
