I'm forwarding this message I recently posted to debian-bugs in order
to see if some of you know how to solve the problem:

Subject: bluez-utils: The inquiry scan (ISCAN) gets turned off
To: Debian Bug Tracking System <[email protected]>
Package: bluez-utils
Version: 3.1-3.1
Severity: important
Whenever I try to discover the local system (Debian computer) from a remote
system (mobile device, or other computer) it can't be found. After
some research I found out that the ISCAN mode is disabled:
--------------------------------------------------------------------
# hciconfig hci0
hci0: Type: USB
BD Address: 00:0E:6D:3B:31:AE ACL MTU: 192:8 SCO MTU: 64:8
UP RUNNING PSCAN
RX bytes:3190 acl:16 sco:0 events:208 errors:0
TX bytes:1840 acl:17 sco:0 commands:105 errors:0
--------------------------------------------------------------------
But according to my hcid.conf file it should be enabled by default for
all devices, I'm using the prepackaged hcid.conf :
--------------------------------------------------------------------
# cat /etc/bluetooth/hcid.conf
#
# HCI daemon configuration file.
#
# HCId options
options {
# Automatically initialize new devices
autoinit yes;
# Security Manager mode
# none - Security manager disabled
# auto - Use local PIN for incoming connections
# user - Always ask user for a PIN
#
security auto;
# Pairing mode
# none - Pairing disabled
# multi - Allow pairing with already paired devices
# once - Pair once and deny successive attempts
pairing multi;
# Default PIN code for incoming connections
passkey "1234";
}
# Default settings for HCI devices
device {
# Local device name
# %d - device id
# %h - host name
name "%h-%d";
# Local device class
class 0x3e0100;
# Default packet type
#pkt_type DH1,DM1,HV1;
# Inquiry and Page scan
pscan enable; iscan enable;
# Default link mode
# none - no specific policy
# accept - always accept incoming connections
# master - become master on incoming connections,
# deny role switch on outgoing connections
lm accept;
# Default link policy
# none - no specific policy
# rswitch - allow role switch
# hold - allow hold mode
# sniff - allow sniff mode
# park - allow park mode
lp rswitch,hold,sniff,park;
}
--------------------------------------------------------------------
In an effort to make the Debian computer visible to other devices
I'm running the following command:
--------------------------------------------------------------------
# hciconfig hci0 piscan
# hciconfig hci0
hci0: Type: USB
BD Address: 00:0E:6D:3B:31:AE ACL MTU: 192:8 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:3294 acl:16 sco:0 events:221 errors:0
TX bytes:1878 acl:17 sco:0 commands:112 errors:0
--------------------------------------------------------------------
But after a while the ISCAN mode gets disabled and I must keep running
hciconfig to make the computer visible again.
I have tried with two USB-BLUETOOTH dongles of different brands
and the problem persists.
I have also tried it in sid and etch with the same results.

You can find a description of the bluez D-Bus API in the
hcid/dbus-api.txt file that comes along with bluez-utils (you'll have to
use version 3.3 since it wasn't included before that).
About D-Bus usage, well, by googling you should be able to find several
places with some documentation, though I have to admit that some of the
higher level bindings lack good documentation. E.g. the lowlevel API
description can be found here:
http://dbus.freedesktop.org/doc/api/html/group__DBus.html
If you want to specifically use the bluez D-Bus API you could e.g. take
a look at the source code of the new bluez-gnome package (which uses the
GLib bindings of D-Bus) or the hcid/dbus-test script which is part of
the bluez-utils package (it uses the python bindings and contains
examples of pretty much every feature of the bluez D-Bus API).

Set the discoverable timeout:
dbus-send --system --dest=org.bluez /org/bluez/hci0 \
org.bluez.Adapter.SetDiscoverableTimeout uint32:100
Get the discoverable timeout:
dbus-send --system --dest=org.bluez --print-reply /org/bluez/hci0 \
org.bluez.Adapter.GetDiscoverableTimeout

No problem :)

Can you, please, point me to some documentation about dbus usage and
how to discover the methods registered by bluez?. Another example will
be nice, something like... How to set the discover timeout with dbus
;^)
Thanks for your help!

Adding "discovto 0;" to hcid.conf should do the trick.
You can change the settings from the command line using dbus-send, but I
don't think it's a good idea to put it into a init script. E.g. the
following would put the device in discoverable mode:
dbus-send --system --dest=org.bluez /org/bluez/hci0 \
org.bluez.Adapter.SetMode string:discoverable

Hi Marcel,
Thanks a lot for your help!

Is there any tool in bluez-utils to achieve that? or some new entries
in the hcid.conf? so it can be done in an init script.

this should have been fixed in bluez-utils-3.3. You have to set the
discoverable timeout to 0 and the mode to "discoverable" over the new
D-Bus API and then it will stay visible forever. Otherwise it goes back
to being non-discoverable after the discoverable timeout.
