D-Bus

These D-Bus commands can be run from terminal or as shell scripts. Useful for scheduling events with fcron, executing from Desktop Command Execution Widget or Queen BeeCon Widget, startup events, install scripts, etc. They should be run as:

run-standalone.sh SCRIPT.sh
run-standalone.sh dbus-send COMMAND

This is important to set up the environment correctly otherwise they may barf. If run as user "user" this is not needed.

Also note that most commands don't need "--print-reply" option. Those that don't need it should be tested without it and this page should be edited.

Phone

Open Phone application

dbus-send --type=method_call --dest=com.nokia.HildonDesktop.AppMgr /com/nokia/HildonDesktop/AppMgr com.nokia.HildonDesktop.AppMgr.LaunchApplication string:"rtcom-call-ui"

Make a phone call

dbus-send --system --type=method_call --print-reply --dest=com.nokia.csd.Call /com/nokia/csd/call com.nokia.csd.Call.CreateWith string:"$NUMBER" uint32:0

Change $NUMBER to phone number you want to call.

End current phone call

dbus-send --system --print-reply --dest=com.nokia.csd.Call /com/nokia/csd/call com.nokia.csd.Call.Release

This will release/end/hangup/reject the current call (or possibly all calls if more then one call is active) or do nothing if no calls are active.

Answer current phone call

dbus-send --system --print-reply --dest=com.nokia.csd.Call /com/nokia/csd/call/1 com.nokia.csd.Call.Instance.Answer

This will answer/pickup the current (first) call.

If you answer the call immediately as you receive the Call Coming D-Bus message the phone seems to be in a specific call state where answering yields a com.nokia.csd.Call.Error.NotAllowed exception.

You need to answer the call after a delay of e.g. 1 s.

Another (probably better) approach is to register to the CallStatus D-Bus message (com.nokia.csd.Call, /com/nokia/csd/call/1, com.nokia.csd.Call.Instance.CallStatus) and wait for a call status >= 2 (=CSD_CALL_STATUS_COMING) after the "Coming" message.

Get IMEI

dbus-send --system --type=method_call --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM/security Phone.Sim.Security.get_imei

Get IMSI

dbus-send --system --type=method_call --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM Phone.Sim.get_imsi

Get SIM status

dbus-send --system --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM Phone.Sim.get_sim_status

Get cellular signal strength

dbus-send --system --print-reply --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_signal_strength

First line is percentage, second is dBm, third unknown.

Get cellular registration status

dbus-send --system --print-reply --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_registration_status

Turn loudspeaker on

dbus-send --type=method_call --dest=com.nokia.osso_hp_ls_controller /com/nokia/osso_hp_ls_controller com.nokia.osso_hp_ls_controller.loudspeaker.force_loudspeaker_on

(These loudspeaker ones don't work on my N900. If I add --print-reply I get "Error org.freedesktop.DBus.Error.ServiceUnknown: The name com.nokia.osso_hp_ls_controller was not provided by any .service files".)

Turn loudspeaker off

dbus-send --type=method_call --dest=com.nokia.osso_hp_ls_controller /com/nokia/osso_hp_ls_controller com.nokia.osso_hp_ls_controller.loudspeaker.force_loudspeaker_off

Turn loudspeaker on (N900)

dbus-send --type=method_call --dest=org.maemo.Playback.Manager \

/org/maemo/Playback/Manager \ org.maemo.Playback.Manager.RequestPrivacyOverride boolean:True

Turn loudspeaker off (N900)

dbus-send --type=method_call --dest=org.maemo.Playback.Manager \

/org/maemo/Playback/Manager \ org.maemo.Playback.Manager.RequestPrivacyOverride boolean:False

Start vibrating

Messaging

New e-mail

dbus-send --type=method_call --dest=com.nokia.modest /com/nokia/modest com.nokia.modest.MailTo string:"mailto:"

Send and receive e-mail

It works, but it takes up to 2 minutes for modest to start refreshing and after that it depends on the speed of the connection how fast it is going to be completed, usually up to 5 seconds, 2G can be a bit slower.

dbus-send --type=method_call --dest=com.nokia.modest /com/nokia/modest com.nokia.modest.SendReceive

Set presence

dbus-send --type=method_call --print-reply --dest=org.freedesktop.Telepathy.MissionControl /org/freedesktop/Telepathy/MissionControl org.freedesktop.Telepathy.MissionControl.SetPresence uint32:2 string:"I'm here"

Note: This method does not work in Maemo 5. Workaround: http://talk.maemo.org/showthread.php?t=55686

Change peak_schedule settings

Check:

run-standalone.sh gconftool-2 -R /apps/activesync

Set (check if yours is named ActiveSyncAccount1):

run-standalone.sh gconftool-2 --set /apps/activesync/ActiveSyncAccount1/schedule/peak_schedule --type=int 15

Where the last number is one of the following (as standard in GUI):

  • 0 = Always on
  • -1 = Manual
  • 15 = Every 15 minutes
  • 30 = Every 30 minutes
  • 60 = Every hour

Networking

Enable ICD log

There are two methods to enable ICD logs

1. Print to the syslog:

  (1)Use the following cmd 
  (2)$ syslogd
  (3)$ icd2 –l0
  (4)The log will print to the /var/log/syslog

2. Print to the standard output

  (1)Get the source code of icd2
  (2)Add the begging of source code of “support/osso-log.h” "#define OSSOLOG_STDOUT"
  (3)$ icd2 –l0
  (4)The log will print to the standard output

Connect to specific saved connection

dbus-send --system --type=method_call --dest=com.nokia.icd /com/nokia/icd com.nokia.icd.connect string:"IAP_ID" uint32:0

IAP_ID is internet access point identifier and can be obtained with the following command:

gconftool -R /system/osso/connectivity/IAP

Find lines which matches /system/osso/connectivity/IAP/<IAP_ID>

For GPRS connections replace "@32@" with a space in IAP_ID string.

Keep in mind that phone has to be disconnected in order to connect via this call. If not, an error message will occur if you add --print-reply to the dbus-send command.

Connect to any saved connection

dbus-send --system --type=method_call --dest=com.nokia.icd /com/nokia/icd com.nokia.icd.connect string:"[ANY]" uint32:0

Disconnect internet

ICD2
dbus-send --print-reply --system --dest=com.nokia.icd2 /com/nokia/icd2 com.nokia.icd2.disconnect_req uint32:0x8000
ICD
dbus-send --system --dest=com.nokia.icd /com/nokia/icd_ui com.nokia.icd_ui.disconnect boolean:true

On PR1.2 : Error org.freedesktop.DBus.Error.UnknownMethod: Method "disconnect" with signature "b" on interface "com.nokia.icd_ui" doesn't exist

Connect (show change connection UI)

dbus-send --system --type=method_call --dest=com.nokia.icd_ui /com/nokia/icd_ui com.nokia.icd_ui.show_conn_dlg boolean:false

If "boolean:true" at the end, one-line notification saying "No saved connections available" appears. Maybe affects more than that? Most likely, boolean:true leads to using saved connections if there are any, and boolean:false forces to display the connection dialog.

Enable cellular radio

dbus-send --system --type=method_call --dest=com.nokia.phone.SSC /com/nokia/phone/SSC com.nokia.phone.SSC.set_radio boolean:true

Disable cellular radio

dbus-send --system --type=method_call --dest=com.nokia.phone.SSC /com/nokia/phone/SSC com.nokia.phone.SSC.set_radio boolean:false

dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:2

Dual

dbus-send --system --type=method_call --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.set_selected_radio_access_technology byte:0

Bluetooth

Identify adapter path

You need to know adapter path in order to send D-Bus call to the right place. You can get it with entering this command into the terminal:

dbus-send --system --print-reply --dest=org.bluez / org.bluez.Manager.ListAdapters | awk -F'"' '/at/ {print $2}'

Enable

Using the adapter path value returned with previous command, for example /org/bluez/906/hci0.

dbus-send --system --type=method_call --dest=org.bluez /org/bluez/906/hci0 org.bluez.Adapter.SetProperty string:Powered variant:boolean:true

This one automatically inserts adapter path:

dbus-send --system --type=method_call --dest=org.bluez $(dbus-send --system --print-reply --dest=org.bluez / org.bluez.Manager.ListAdapters | awk -F'"' '/at/ {print $2}') org.bluez.Adapter.SetProperty string:Powered variant:boolean:true

Disable

dbus-send --system --type=method_call --dest=org.bluez /org/bluez/906/hci0 org.bluez.Adapter.SetProperty string:Powered variant:boolean:false

With auto-discovery of adapter path:

dbus-send --system --type=method_call --dest=org.bluez $(dbus-send --system --print-reply --dest=org.bluez / org.bluez.Manager.ListAdapters | awk -F'"' '/at/ {print $2}') org.bluez.Adapter.SetProperty string:Powered variant:boolean:false

Connect to specific device

devmac=00:11:22:33:44:55
service=AudioSink

adapter=$(dbus-send --system --print-reply --dest=org.bluez / org.bluez.Manager.ListAdapters | awk -F'"' '/at/ {print $2}')
device=$(dbus-send --system --print-reply --dest=org.bluez ${adapter} org.bluez.Adapter.FindDevice string:${devmac} | sed -ne 's/^.*object path //p' -e 's/"//g')
dbus-send --system --type=method_call --print-reply --dest=org.bluez ${device} org.bluez.${service}.Connect

Change the AudoSink to any service and the devmac to the MAC of bluetooth device.

Check for updates

dbus-send --type=method_call --dest=com.nokia.hildon_application_manager /com/nokia/hildon_application_manager com.nokia.hildon_application_manager.check_for_updates

Open link in browser

dbus-send --system --type=method_call --dest=com.nokia.osso_browser /com/nokia/osso_browser/request com.nokia.osso_browser.load_url string:"google.com"

Open a pdf file with the default pdf reader application

dbus-send --print-reply --dest=com.nokia.osso_pdfviewer /com/nokia/osso_pdfviewer com.nokia.osso_pdfviewer.mime_open string:/home/user/MyDocs/.documents/file_name.pdf

Open folder

dbus-send --print-reply --dest=com.nokia.osso_filemanager /com/nokia/osso_filemanager com.nokia.osso_filemanager.open_folder string:/home/user/MyDocs/


Set volume

dbus-send --type=method_call --dest=com.nokia.mafw.renderer.Mafw-Gst-Renderer-Plugin.gstrenderer /com/nokia/mafw/renderer/gstrenderer com.nokia.mafw.extension.set_extension_property string:volume variant:uint32:50

The value can be between 0 and 100.

Reboot

dbus-send --system --type=method_call --print-reply --dest=com.nokia.mce "/com/nokia/mce/request" com.nokia.mce.request.req_reboot

This is same as rebooting from power key menu (needs uncommenting in certain XML file to appear) and has been identified as insecure way to reboot the device (no filesystem synchronization, etc.). Better command is to simply enter "reboot" in root terminal.

Shutdown

dbus-send --system --type=method_call --print-reply --dest=com.nokia.mce "/com/nokia/mce/request" com.nokia.mce.request.req_shutdown

See warning at reboot D-Bus call (needs testing).

Show dashboard

dbus-send /com/nokia/hildon_desktop com.nokia.hildon_desktop.exit_app_view

Other

D-Bus Scripts

You can also use dbus-scripts to execute any command when various actions are triggered on D-Bus.

Panucci (pause)

dbus-send --type=method_call --dest=org.panucci.panucciInterface /panucciInterface org.panucci.panucciInterface.playPause

Device Orientation

dbus-send --system --print-reply --dest=com.nokia.mce /com/nokia/mce/request com.nokia.mce.request.get_device_orientation

GConf

Reset GPRS data counter

The commands are PR1.2 compliant and do not work on previous versions.

gconftool-2 -u /system/osso/connectivity/network_type/GPRS/gprs_home_rx_bytes
gconftool-2 -u /system/osso/connectivity/network_type/GPRS/gprs_home_tx_bytes
gconftool-2 -s /system/osso/connectivity/network_type/GPRS/gprs_home_reset_time --type=string $(date +%s)

Command line

Enable FM Transmitter

/usr/bin/fmtx_client -p 1

Disable FM Transmitter

/usr/bin/fmtx_client -p 0

GStreamer

Take a picture with front camera

gst-launch v4l2src device=/dev/video1 num-buffers=1 ! ffmpegcolorspace ! jpegenc ! filesink location=frontcam.jpg

Shoot photo after 10 seconds

The camera application must be off for it to work. And of course the camera shutter must be open...gst-launch comes with gstreamer-tools (or gst-launch-0.10 and gstreamer0.10-tools)

/bin/sleep 10 ; /usr/bin/gst-launch v4l2camsrc device=/dev/video0 num-buffers=1 \! video/x-raw-yuv,width=2592,height=1968  \! ffmpegcolorspace \! jpegenc \! filesink location=/home/user/MyDocs/DCIM/photo.jpg

To shoot from the front camera, change /dev/video0 to /dev/video1 and the proper resolution:

/bin/sleep 10 ; /usr/bin/gst-launch v4l2camsrc device=/dev/video1 num-buffers=1 \! video/x-raw-yuv,width=640,height=480  \! ffmpegcolorspace \! jpegenc \! filesink location=/home/user/MyDocs/DCIM/photo.jpg

Other way:

/bin/sleep 10; /usr/bin/gst-launch v4l2camsrc ! ffmpegcolorspace ! jpegenc ! identity error-after=1 ! filesink location=/home/user/MyDocs/DCIM/photo.jpg

Send dialog notification (orange multi line popup requiring user interaction)

import dbus
def show_notification_dialog(message, mode="single"):
  bus = dbus.SystemBus()
  iface = dbus.Interface(bus.get_object('org.freedesktop.Notifications',
                                        '/org/freedesktop/Notifications'),
                                        'org.freedesktop.Notifications')
  if mode == "single":
      iface.SystemNoteInfoprint(message)
  elif mode == "multiline":
      iface.SystemNoteDialog(str(message), dbus.UInt32(0), 'Ok')

This function allows you to show notification either with multiline (on Maemo pre-5 it will show a dialog with an "Ok" button) or single line (tiny notifications hiding automatically).

Take a screenshot

import gtk.gdk
 
w = gtk.gdk.get_default_root_window()
sz = w.get_size()
print "The size of the window is %d x %d" % sz
pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False,8,sz[0],sz[1])
pb = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,sz[0],sz[1])
if (pb != None):
  pb.save("screenshot.png","png")
  print "Screenshot saved to screenshot.png."
else:
  print "Unable to get the screenshot."

There is also a way using PyQt:

import sys
import time
from PyQt4.QtGui import QPixmap, QApplication
app = QApplication(sys.argv)
file = "/home/user/MyDocs/.images/Screenshots/Screenshot-"+time.strftime("%Y%m%d")+"-"+time.strftime("%H%M%S")+".png"
QPixmap.grabWindow(QApplication.desktop().winId()).save(file, 'png')

Make an "Email Style" notification dialog

import dbus
 
bus = dbus.SessionBus()
proxy = bus.get_object('org.freedesktop.Notifications', '/org/freedesktop/Notifications')
interface = dbus.Interface(proxy,dbus_interface='org.freedesktop.Notifications')
interface.Notify('Notification', 0, 'control_bluetooth_paired', 'Testing 123', 'Hello World', [], {}, 0)
