Thanks for your replay. Do you know how long I wait to get the getRoute response.
//my code is //determine the physical hop: how far Ni is from GC res=call RoutingTable.getRoute(GCAddress[gid], &rt_info); //affichage parameter de la route printf("EndDevice %02i: Printing route info res=%s\n", TOS_NODE_ID, errType(res)); //if the route exist if(res==SUCCESS) { print_route(&rt_info, sizeof(rt_info_t)); //save the physicalhop to the GC physicalHop[gid]=rt_info.hopcnt; } Else { I wait ==> how long??? //again.. res=call RoutingTable.getRoute(GCAddress[gid], &rt_info); } -----Original Message----- From: tinyos-help-boun...@millennium.berkeley.edu [mailto:tinyos-help-boun...@millennium.berkeley.edu] On Behalf Of Daniel Minder Sent: Tuesday, August 23, 2011 9:41 AM To: tinyos-help@millennium.berkeley.edu Subject: Re: [Tinyos-help] question about tymo Hi Omar, it's quite a while that I played around with TYMO - and actually it never worked satisfyingly. So, I can only answer this question: > Moreover, the command getRoute returns SUCCESS only if the nodes are > one hop far from (directly connected), and it returns EBUSY if the > nodes are more than one-hop far from. This is how TYMO works! It only knows its direct neighbors. If you ask for a route to a different node, it returns an EBUSY but sends out a route request packet to discover this route. So, you have to wait and ask for the route again later. This is also TYMO is doing.
