Hi vinypant,

I don't know which way that the client found and sent a request joining session to your host application. But I suggest that you should use about service which will help your client can advertise some information about itself(bus name, application ID, device ID,...) then your host application will receive the client's information and decide that accept the joining session request or not.

Thanks, Cong Nga Le

Hi Cong Nga Le, Thank you i used about service listener and i am able to receive data now but i am not able to figure out how to know if a client unique name is no longer available , is there some callback for that.

Hi Cong Nga Le, There is one unannounce api given in aboutobj using which client can unnannounce its details , but how to let others know that client has unannouced itself , is there some callback ? I am storing all the discovered clients in a map , so i need to know if someone has unannounded itself.

Hi vinypant, I don't know which binding language that you are using to implement but there are two ways(I knew) can figure out that the client is available or not. 1. In java binding(Android) language we have a callback is called "deviceLost", I don't know about other languages. 2. In C/C++ we use ping method to check the client. You can take a look on PingContext function on this example https://git.allseenalliance.org/cgit/core/alljoyn.git/tree/services/about/cpp/samples/AboutClientSample/AboutClientMain.cc?h=refs/heads/RB14.12
