[Bluez-users] dbus.DBusException: org.bluez.input.Error.AlreadyExists: Input Already exists

[Dick]

Hi all,

I'm trying the new input service with my Logitech dinovo desktop but I can't get
it working. I've read http://wiki.bluez.org/wiki/HOWTO/InputDevices and
manufactured/stolen the following python script:

import dbus
bus = dbus.SystemBus()
bmgr = dbus.Interface(bus.get_object('org.bluez', '/org/bluez'),
'org.bluez.Manager')
bus_id = bmgr.ActivateService('input')

# All input messages should be sent to this address
print bus_id

imgr = dbus.Interface(bus.get_object(bus_id, '/org/bluez/input'),
'org.bluez.input.Manager')

# device creation
#path = imgr.CreateDevice('00:07:61:69:27:XX')
path = imgr.CreateDevice('00:07:61:68:CA:XX')
idev = dbus.Interface (bus.get_object(bus_id, path), 'org.bluez.input.Device')

# host initiated connection
print idev.GetName()
idev.Connect()

This results in:

:1.30
Logitech Bluetooth Keyboard
Traceback (most recent call last):
  File "test.py", line 19, in ?
    idev.Connect()
  File "//usr/lib/python2.4/site-packages/dbus/proxies.py", line 169, in __call__
    reply_message = self._connection.send_message_with_reply_and_block(message,
timeout)
dbus.DBusException: org.bluez.input.Error.ConnectionAttemptFailed: Host is down

I've tried some fiddling with the connect button and rm-/insmod-ed hidp (from
linux-2.6.21).

Could someone please give me some hints?

Thanks,
Dick

no need to call Connect(), because HID devices will re-connect to you.

Thank you very much for your answer, I've tried without Connect() but my dinovo
keyboard and mouse seem to connect and after some seconds disconnect (as far as
I can see with hcitool con).
Can I see why they are disconnected? I should be able to use the keyboard and
mouse as input devices this way shouldn't I?

run "hcidump -X -V" to see what actually happens.

Hi Marcel,

I've tried hcidump but its output doesn't help me ;) As far as I understand the
output it in "Connection pending - Authorization pending" then "Connection
successful" and finally in "Connection refused - PSM not supported" do you know
what this means?

This is the tail of hcidump:
