When we connect to an empty chat room, the previous messages are not showing because before we should have sent the offline users that sent that messages.
The message structure we need to send is <o u="USER_ID(int)" s="1" N="USER_NAME(str)" a="USER_AVATAR(str)" h="USER_HOME(str)" n="USER_NICKNAME(str)" />
