I am working on the car infotainment system.
The details of the system is given below.
Platform : LINUX
IPC : Dbus
BT Stack : Bluez
Module : AddressBook
When ever i am selecting the Contacts or the Call logs the below mentioned Dbus calls are invoked and became success.
dbus_connection_send_with_reply_and_block(session_bus, msg, -1, &err);
In some cases the above shown Dbus calls are failing and giving the below errors.
Error Message:Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist
I have no clues why this Dbus call had failed.
Please help me in this regard.
Note : Both the Dbus calls are invoked to get the data from Bluez.
Thanks and regards,

You might try using a dbus viewer/browser to double-check the dbus calls you are trying to make. Qt has one called qdbus (command-line, or qdbusviewer GUI) which comes in the qt5-dev-tools package.
Checking the docs it looks like that Get method takes two parameters: the interface name and the property name.
