So the status is this:
1) The USB Bluetooth Dongle is inserted, and recognized.
root@server:~# lsusb Bus 002 Device 002: ID 8087:8000 Intel Corp. Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Bus 001 Device 002: ID 8087:8008 Intel Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
2) I installed the following packages from buster without incidents:
bluez amd64 5.50-1 bluetooth all 5.50-1 libical3 amd64 3.0.4-3 bluez-obexd amd64 5.50-1 bluez-tools amd64 2.0~20170911.0.7cb788c-2 rfkill amd64 2.33.1-0.1
3) bluetooth is not blocked:
root@server:~# rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no
4) bluetooth service is running:
root@server:~# service bluetooth start root@server:~# service bluetooth status ? bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2020-03-19 12:42:35 CET; 1min 9s ago Docs: man:bluetoothd(8) Main PID: 29677 (bluetoothd) Status: "Running" Tasks: 1 (limit: 4333) Memory: 1.6M CGroup: /system.slice/bluetooth.service mq29677 /usr/lib/bluetooth/bluetoothd
I have no access to X, so I cannot run blueman
How can I now make the device visible and start the pairing process with the printer just from console, in order to install the printer on this computer?
UPDATE1: Finally I was able to see the printer with
root@server~# bluetoothctl Agent registered
[bluetooth]# help Menu main: Available commands: ------------------- advertise Advertise Options Submenu scan Scan Options Submenu gatt Generic Attribute Submenu list List available controllers show [ctrl] Controller information select <ctrl> Select default controller devices List available devices paired-devices List paired devices system-alias <name> Set controller alias reset-alias Reset controller alias power <on/off> Set controller power pairable <on/off> Set controller pairable mode discoverable <on/off> Set controller discoverable mode agent <on/off/capability> Enable/disable agent with given capability default-agent Set agent as the default one advertise <on/off/type> Enable/disable advertising with given type set-alias <alias> Set device alias scan <on/off> Scan for devices info [dev] Device information pair [dev] Pair with device trust [dev] Trust device untrust [dev] Untrust device block [dev] Block device unblock [dev] Unblock device remove <dev> Remove device connect <dev> Connect device disconnect [dev] Disconnect device menu <name> Select submenu version Display version quit Quit program exit Quit program help Display help about this program export Print evironment variables
ok, so I went like this:
[bluetooth]# show Controller 00:15:83:F4:BA:F5 (public) Name: server Alias: server Class: 0x00000104 Powered: yes Discoverable: no Pairable: yes UUID: Generic Attribute Profile (00001801-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb) UUID: PnP Information (00001200-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) UUID: Generic Access Profile (00001800-0000-1000-8000-00805f9b34fb) Modalias: usb:v1D6Bp0246d0532 Discovering: no [bluetooth]#
and then I started:
[bluetooth]# power on Changing power on succeeded [bluetooth]# discoverable on Changing discoverable on succeeded [CHG] Controller 00:15:83:F4:BA:F5 Discoverable: yes [bluetooth]# devices Device 06:0E:3C:5C:1A:FD ENVY 5000 series [bluetooth]#
then I go
[bluetooth]# pair 06:0E:3C:5C:1A:FD Attempting to pair with 06:0E:3C:5C:1A:FD [CHG] Device 06:0E:3C:5C:1A:FD Connected: yes [CHG] Device 06:0E:3C:5C:1A:FD Name: OfficeJet 5200 series [CHG] Device 06:0E:3C:5C:1A:FD Alias: OfficeJet 5200 series [CHG] Device 06:0E:3C:5C:1A:FD ServicesResolved: yes
and after some seconds ...
[CHG] Device 06:0E:3C:5C:1A:FD ServicesResolved: no [CHG] Device 06:0E:3C:5C:1A:FD Connected: no Failed to pair: org.bluez.Error.AuthenticationCanceled [bluetooth]#
The printer device has something called Smart Bluetooth so I said to myself maybe I must not "pair" but "trust" so i went:
[bluetooth]# trust 06:0E:3C:5C:1A:FD Changing 06:0E:3C:5C:1A:FD trust succeeded [bluetooth]#
and so I stuck again I still can not see the printer on http://127.0.0.1:631
Any hint ?
After some hours I found the answer.
first you must disable the enable/disable the simple pairing mode. depending on what your device is supporting. I do not need it so I disabled it.
hciconfig sspmode off
The next I disabled the timeout, because I want the printer to stay connected until I disconnect him. in /etc/bluetooth/input.conf
Just change it to 0 and the devices stay connected.
