Apr 23 09:13:29 <brolin_empey> sunshavi: Can you use lsusb or lspci or similar for the bus used to connect the Bluetooth controller to check if the Bluetooth controller is present?
Apr 23 15:58:33 <sunshavi> brolin_empey: I ended used this one: systemctl list-units -t device | grep hci0
Apr 23 17:57:44 <brolin_empey> sunshavi: OK.  Is systemctl part of systemd?
Apr 23 17:58:14 <sunshavi> Yes. It is
Apr 23 18:00:58 <brolin_empey> OK, I thought so.  I am not very familiar with systemd so did not think of using it.
Apr 23 18:05:25 <sunshavi> bt-adapter is part of bluez-tools
Apr 23 18:05:37 <sunshavi> But bt-adapter core dumps when no bluetooth dongle is present
Apr 23 18:06:23 <sunshavi> I needed a different and simple way of detecting if bluetooth dongle is present at boot time. 
Apr 23 18:26:50 <brolin_empey> OK.
Apr 23 18:43:42 <KotCzarny> sunshavi: how about lsusb?
Apr 23 18:43:45 <KotCzarny> or hciconfig ?
Apr 23 18:52:16 <sunshavi> KotCzarny: hciconfig is not present on mainline :(
Apr 23 18:52:30 <KotCzarny> are you sure?
Apr 23 18:53:16 <sunshavi> KotCzarny: lsusb I tried it by I could have different manufacturers for the bluetooth dongle. 
Apr 23 18:53:47 <KotCzarny> hciconfig is part of bluez package
Apr 23 18:54:06 <KotCzarny> at least on devuan ascii
Apr 23 18:54:23 <sunshavi> not so sure. But at the moment on archlinux-arm with mainline no hciconfig
Apr 23 18:54:46 <KotCzarny> is there some equivalent of 'apt-file search' in archlinux?
Apr 23 18:55:28 <sunshavi> pacman -Qs perhaps
Apr 23 18:55:43 <sunshavi> https://termbin.com/n7fo
Apr 23 18:56:12 <KotCzarny> https://old.reddit.com/r/archlinux/comments/5x9yle/where_has_hciconfig_gone/
Apr 23 18:56:19 <KotCzarny> heh
Apr 23 18:56:54 <KotCzarny> if you dont mind installing bluez-utils-compat, you should be able to see any hciX device present
Apr 23 18:57:23 <sunshavi> pacman -Qs bluez
Apr 23 18:59:09 <sunshavi> https://termbin.com/l82d
Apr 23 18:59:59 <sunshavi> bluez-utils-compat. It would need to be compiled manually or with yaourt. No package is available by default. But It could do the job
Apr 23 19:00:35 <KotCzarny> i suspect grepping dmesg or checking for files somewhere in /sys could do the job too
Apr 23 19:01:24 <sunshavi> Yes. But having and uptime of months on opi+2e could affect it?
Apr 23 19:01:35 <KotCzarny> affect what?
Apr 23 19:01:44 <KotCzarny> i must have missed original question/problem
Apr 23 19:02:17 <sunshavi> I was usig at boottime bt-adapter -l for detecting if bluetooth dongle is present
Apr 23 19:02:34 <KotCzarny> something along the lines: Feb 20 15:00:24 hostname bluetoothd[4568]: HCI dev 0 registered
Apr 23 19:02:55 <KotCzarny> or btmgmt info
Apr 23 19:02:56 <sunshavi> But on my compaq n600c machine. It took 30s when booting for showing a "core dump" message
Apr 23 19:03:34 <KotCzarny> you can disable bt service 
Apr 23 19:03:38 <KotCzarny> then run it manually
Apr 23 19:03:42 <sunshavi> You are right about 'btmgmt info'
Apr 23 19:04:33 <sunshavi> when bt dongle is present It should  connect to a bt-NAP server present in the room :)
Apr 23 19:04:51 <sunshavi> I think btmgmt info is the 'one'
Apr 23 19:05:04 <KotCzarny> tbh i grabbed that command from: https://wiki.archlinux.org/index.php/bluetooth
Apr 23 19:05:20 <KotCzarny> you should really read docs :)
Apr 23 19:05:25 <sunshavi> I just need to check if it core dumps when bt dongle is not present and It should be ok
Apr 23 19:05:29 <KotCzarny> archlinux has quite a nice documentation
Apr 23 19:06:17 <sunshavi> Yes. You are right. I missed that. my fault
Apr 23 19:06:46 <sunshavi> thx. I am going to check if it works in a few minutes
Apr 23 19:20:48 <sunshavi> It worked. for detecting when bluetooth dongle is not present "btmgmt info | grep '0 items'"
Apr 23 19:37:27 <KotCzarny> it will fail with 10 items etc
Apr 23 19:37:28 <KotCzarny> :)
Apr 23 19:37:42 <KotCzarny> unlikely situation but.. 
Apr 23 19:42:49 <sunshavi> :)
Apr 23 19:43:57 <sunshavi> I just have nine usb-ports ;)
Apr 23 19:44:07 <KotCzarny> usb hubs exist
Apr 23 19:44:53 <sunshavi> I have two usb-hubs. That's the reason I have nine usb-ports on opi+2e
Apr 23 19:45:14 <KotCzarny> :)
