From: Jose on 10 Jul 2010 19:21 Hello to everyone, I have this function in my slave computer that receive signal from the master, it start fine, the problem is when I call the function pausexx in the uicontrol, I forze to the slave to do not communicate with the master, but when I call the function pausexx again to restart the communication the communication is lost, and I would like to recovery it, but i do not know how I can do it. Thanks in advance. function panel close all clc clear all %figure global sock global datax ai % Connect to the server on port 3000 % servername=169.254.245.219 svrsock = mslisten(3000); sock=msaccept(svrsock); msclose(svrsock); w=waitforbuttonpress disp('Button click') % Receive the variable -- 5 second % timeout before failure epsn=0; global sdata global adc global suc global datax global sm_ack global sm_init global sm_startmove global sm_endmove global sm_adc global sm_elpsn % global dir_bk global dir_fwd global el_notloaded global el_up global el_surf global el_cx global el_broken global hz stat % receive the variable1 over the socket sm_ack=6; sm_init=5; sm_startmove=1; sm_endmove=2; sm_adc=3; sm_elpsn=4; dir_bk=0; dir_fwd=1; el_notloaded=0; el_up=1; el_surf=2; el_cx=3; el_broken=-1; s=receivestructure(sock) sendvar2m=1; stat=true t1 = timer('TimerFcn',{@timerFun},'executionmode','fixedrate'); start(t1) global sendvar2m global sm_ack global sm_init global sm_startmove global sm_endmove global sm_adc global sm_elpsn % global dir_bk global dir_fwd global el_notloaded global el_up global el_surf global el_cx global el_broken global hz stat function timerFun(obj,~) stat if stat==true hstop=uicontrol (gcf,'String','Stop','Position',[10,10,60,20],'Callback','pausexx'); if sendvar2m ~=0 s=receivestructure(sock) else suc=1 end if sendvar2m > 0 s.smtype=sm_startmove; s.username='Jose'; s.eldir=dir_fwd; s.elno=3; sendstructure(sock,s) s pause(hz) s.smtype=sm_endmove; s.elno=3; sendstructure (sock,s) s elseif sendvar2m < 0 s.smtype=sm_startmove; s.eldir=dir_bk; s.username='Jose'; s.elno=3; sendstructure(sock,s); pause(hz) s.smtype=sm_endmove; s.elno=3; sendstructure (sock,s); else s.smtype=sm_elpsn; s.elno=3; end end end % close the socket msclose(sock); %end end function pausexx global stat stat =~ stat; return end

Your function calls a large number of other functions that you have not provided (either directly or by linking to where you obtained them; since they're likely quite long, please don't post them directly.) It also looks like it depends on some server listening for a connection on port 3000 -- not everyone here will have the ability or knowledge to set up a server and open a port on that server. You're likely going to need to work with whomever gave you the functions "mslisten", "msaccept", "msclose", etc. to diagnose what's going on. At some point, you may also need/want to involve Technical Support -- but I think that would probably be premature at this point. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
