Details

I tried to make a bluetooth keyboard connect at startup. Therefore, after adding bluetooth to rc.conf's DAEMONS,
I enabled HIDD and added "--connect ##:##:##:##:##:##" to the HIDD_OPTIONS in /etc/conf.d/bluetooth, as indicated here: https://wiki.archlinux.org/index.php/Bluetooth_Keyboard

This doesn't work, because /etc/rc.d/bluetooth adds the option "--server" (see line 49) at all times, adding upt to the call
"/usr/bin/hidd --timeout 8 --master --server --connect ##:##:##:##:##:## --server" when starting hidd. But tests show, that connecting will not take place unless the --connect option is the last one (shown below.) So either this is an upstream bug and the bluez guys should should try to get their inputs parsed right, or the script needs an update, removing the --server option and ensuring in some other way that it is present in the final call. I can't reach anyone from bluez without subscribing to things, so I file a bug here.

Additional info:
Name : bluez
Version : 4.96-1

Steps to reproduce:
comment out line 13 in conf.d/bluetooth to disable HIDD for a second, then emulate the starting of bluetoothd and hidd as in the script, while typing wildly on the keyboard:

This works:
[root@machine]# /etc/rc.d/bluetooth stop; /etc/rc.d/bluetooth start; hidd --master --server --connect 78:CA:39:4F:73:59
:: Stopping bluetooth subsystem: pand dund rfcomm hidd bluetoothd [DONE]
:: Starting bluetooth subsystem: bluetoothd [DONE]


This doesn't, but this is how the script tries to do it:
[root@machine]# /etc/rc.d/bluetooth stop; /etc/rc.d/bluetooth start; hidd --master --connect 78:CA:39:4F:73:59 --server;
:: Stopping bluetooth subsystem: pand dund rfcomm hidd bluetoothd [DONE]
:: Starting bluetooth subsystem: bluetoothd [DONE]
"Can't get device information: No route to host"


This works, and is how the script might want to do it:
[root@machine]# /etc/rc.d/bluetooth stop; /etc/rc.d/bluetooth start; hidd --server --master --server --connect 78:CA:39:4F:73:59;
:: Stopping bluetooth subsystem: pand dund rfcomm hidd bluetoothd [DONE]
:: Starting bluetooth subsystem: bluetoothd [DONE]
For ten seconds the keyboard doesn't work. Works afterwards.

--server flag moved in the HIDD_OPTIONS

The smaller file is /etc/conf.d/bluetooth, the bigger one /etc/rc.d/bluetooth.

To mention it explicitly: This works for me now, by just altering line 49 in /etc/rc.d/bluetooth to $HIDD_EXEC --server $HIDD_OPTIONS instead of $HIDD_EXEC $HIDD_OPTIONS --server, may $HIDD_OPTIONS in /etc/conf.d/bluetooth contain an additional "--server" or not, as long as just the --connect" statement comes last. All I'm asking for is this to be updated in the repository package, as others might follow those instructions in the wiki, too.

Confirm: I am having the same problems. Editing /etc/rc.d/bluetooth in the way described above indeed resolves the problem.
