suppose i plot line
BK=line([X,DCH_coord(1)],[Y,DCH_coord(2)],'marker','*','MarkerSize',10);
BK2=line([XX,DCH_coord(1)],[YY,DCH_coord(2)],'marker','*','MarkerSize',10);
for i=1:4
%sender to receiver
set(BK,'color','r','LineWidth',3),pause(.4)
set(BK,'color','k','LineWidth',3),pause(.4)
set(BK2,'color','r','LineWidth',3),pause(.4)
set(BK2,'color','k','LineWidth',3),pause(.4)
delete(BK); %for deleting the line
delete(BK2); % for deleting the line
%reverse receiver to sender
set(BK2,'color','r','LineWidth',3),pause(.4)
set(BK2,'color','k','LineWidth',3),pause(.4)
set(BK,'color','r','LineWidth',3),pause(.4)
set(BK,'color','k','LineWidth',3),pause(.4)
delete(BK2); %for deleting the line
delete(BK); % for deleting the line
end

try setting the linestyle to none so that the line becomes invisible instead of deleting it
than you can still use the handle in a subsequent call, just set the linestyle again to '-' to make it visible
