Re: [Bluez-users] hci0 only comes up with PSCAN (no ISCAN)

["Claudio Takahasi" <cktakahasi@gmail.com>]

Hi folks,

The release 3.X introduced the D-Bus methods for adapter setup and
basic remote services(inquiry, name, manufacturer, ...). Some bugs
related to discoverable mode were detected but they are now fixed in
the release 3.4. The adapter interface supports the following
discoverable modes:
discoverable: PSCAN ISCAN
connectable: PSCAN
off: NOSCAN

The default discoverable timeout is 180sec. If you set it to 0 +
discoverable mode to "discoverable" the device will be always visible.
If you set the discoverable timeout to X + mode to discoverable, the
mode will be changed automatically to connectable mode after X
seconds.

While we don't have good client application to manage this methods you
can send commands using dbus-send:
$dbus-send --system --type=3Dmethod_call --print-reply --dest=3Dorg.bluez
/org/bluez/hci0 org.bluez.Adapter.SetDiscoverableTimeout uint32:0
$dbus-send --system --type=3Dmethod_call --print-reply --dest=3Dorg.bluez
/org/bluez/hci0 org.bluez.Adapter.SetMode string:discoverable

BR,
Claudio.
