Openmoko uses D-Bus, a message bus system which provides a simple way for applications to talk to one another and to be available as services in the system. If the application providing the service is not running when a message is sent, the application will be started.
There are two separate busses:
- a system bus for root which runs whenever the phone is on
- a session bus which is started for the user when X starts
Session bus services
These can at least be defined in /usr/share/dbus-1.0/services/ and /usr/share/dbus-1/services/
System bus services
There is information about these in /etc/dbus-1/system.d/
Accessing the services
For simple uses, there's a command mdbus. Try
to explore the DBus environment.
For example, to dial a number (using FSO milestone 3):
mdbus -s org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.Call.Initiate '12345' 'voice'
To use D-Bus in Python, the package python-dbus needs to be compiled and installed. Note that since the interfaces change over time you might want to read the source code of zhone from git.freesmartphone.org to get examples of current API.
To dial a number:
#!/usr/bin/env python import dbus bus = dbus.SessionBus() gsm_device_obj = bus.get_object("org.freesmartphone.ogsmd", "/org/freesmartphone/GSM/Device") gsm_call_iface = dbus.Interface(gsm_device_obj,'org.freesmartphone.GSM.Call') proxy = bus.get_object("org.openmoko.Dialer", "/org/openmoko/Dialer") gsm_call_iface.Initiate("12345", "voice")
To run the program use the following:
dbus-launch python my_program.py
