Re: USB insertion event on Tizen through dbus

[Rees, Kevron]

The way you are listening for signals seems strange.  This is the code
I have used:

object->handle =

g_dbus_connection_signal_subscribe(g_bus_get_sync(G_BUS_TYPE_SYSTEM,

  NULL, NULL),

   "org.automotive.message.broker",

   "org.freedesktop.DBus.Properties",

   "PropertiesChanged",

   object_path.c_str(), NULL,

   G_DBUS_SIGNAL_FLAGS_NONE,

   SignalCallback, &amb_objects_,

   NULL);

Hope that helps.

Hello,

I have checked dbus-monitor --system. Its shows signals when USB device is 
inserted.
Thanks!!

You didn't tell us whether dbus-monitor --system shows those signals being 
emitted.

RE: USB insertion event on Tizen through dbus

[Ruchi Sharma]

Hi All,



Thanks for your reply.

I checked that udisk daemon is running as "udisksd".

I ran "udisksctl dump" , it gives logs on USB insertion which shows it is using 
"org.freedesktop.UDisks2" service.



Below is the code snapshot which I am using to get USB insertion event using 
GDBus. But I am not able to get USB insertion events. Kindly let me know if I 
am doing something wrong.

Thanks!!



/Code snapshot**/



GDBusConnection *connection;

GDBusMessage* message;

GDBusProxy *proxy;

GError *error = NULL;



connection = g_bus_get_sync(DBUS_BUS_SYSTEM,NULL,NULL);

if (connection == NULL)
{
  g_printerr ("Failed to open connection to bus: %s\n",error->message);
  g_error_free (error);
  exit (1);
}
else
{
printf("Got a connection to DBUS_BUS_SYSTEM\n");
}



 proxy = g_dbus_proxy_new_sync(connection, G_DBUS_PROXY_FLAGS_NONE , NULL, 
"org.freedesktop.UDisks2", "/org/freedesktop/UDisks2", 
"org.freedesktop.UDisks2", NULL, NULL);



if(proxy == NULL)
 {
g_printerr ("Failed To Create A proxy...: %s\n", error->message);
g_error_free (error);
exit(1);
 }
 else
   printf("Probably got a connection to the correct interface...\n");



g_signal_connect(proxy,"g-signal",(GCallback)device_added,NULL);



   g_signal_connect(proxy,"g-signal",(GCallback)device_removed,NULL);



 loop=g_main_loop_new(NULL,FALSE);

 g_main_loop_run (loop);

 g_error_free (error);

 return 0;

Use gdbus or QtDBus.

First of all, please do not write any new code using dbus-glib. It's 
maintainer has publicly asked that people don't do that. That library is 
entirely deprecated and code should move off it as soon as possible.

Have you verified that udisks-daemon is running on Tizen? Run dbus-monitor --
system and see if the signals are emitted when you insert a USB device and see 
if udisksctl dump shows the device after it's been inserted.

USB insertion event on Tizen through dbus

[Ruchi Sharma]

Hi All,

I am working on Tizen IVI March release.
I am trying to get USB insertion/removal events through dbus APIs. I am using 
UDisks service.
Below is the snapshot of code:

connection = dbus_g_bus_get(DBUS_BUS_SYSTEM,NULL);
proxy=dbus_g_proxy_new_for_name(connection,"org.freedesktop.UDisks","/org/freedesktop/UDisks","org.freedesktop.UDisks");

dbus_g_proxy_add_signal(proxy,"DeviceAdded",DBUS_TYPE_G_OBJECT_PATH, 
G_TYPE_INVALID);
dbus_g_proxy_connect_signal(proxy,"DeviceAdded",(GCallback)device_added,NULL,NULL);

dbus_g_proxy_add_signal(proxy,"DeviceRemoved",DBUS_TYPE_G_OBJECT_PATH, 
G_TYPE_INVALID);
dbus_g_proxy_connect_signal(proxy,"DeviceRemoved",(GCallback)device_removed,NULL,NULL);

I am checking "connection" and "proxy" and they are not null.
But still I am not able to call callbacks on insertion and on removal of USB.

The above mentioned code works on ubuntu fine. I have checked that 
udisks-daemon is running on ubuntu.

Can anybody help me on this or is there any other way to get evets of USB 
insertion/removal?
Thanks !!

Regards,
Ruchi
