Yes, it is possible.

All you have to do is this:

int lineaStatus = [[Linea sharedDevice] connstate];

Them just compare them to the different connection states like this.

   if(lineaStatus == CONN_DISCONNECTED) {
           //Device is connected
   } else if(status == CONN_CONNECTED) {
            //Device is disconnected. 
   }
