Before moving on to msg-listing function implementation, we need bMessage parser to check the messages. I saw in the below link http://comments.gmane.org/gmane.linux.bluez.kernel/22126 that someone had already implemented the parser it seems. Btw Do we need to implement the D-Bus Api's for this? or a simple function implementation that retrieves and parse all the messages from the system directory, since we don’t have any message service running at the back-end.
