The warning can be safely ignored, as the constant is compared to a unsigned integer. > > The other problem I am having is while compiling the application to TOSSIM. > It gives an error saying that "am_addr_t" has a conflicting types for > "addr_t" as at /usr/cygwin/include/types.h , it is defined as > > > typedef char *addr_t; > whereas in "routing.h" in /tos/lib/net/tymo/ … it is defined as > > typedef am_addr_t addr_t; > Apparently, compiling for tossim makes use of some files that are not used otherwise. I am afraid I cannot be of great help here, as I've never used cygwin, and thus don't get these errors.

These constants are defined so that it is possible to program the same test app on all nodes. The code then behaves differently depending on if the node is ORIGIN, TARGET or some other node. I've been using telosb motes, so I didn't face the node id issue. DYMO and the transport protocol use the AM address to identify nodes, so if you know how to set the AM address at compile time, it should work. > > Can you also share the "java" application you wrote for BaseStation or did > you just use generic "Listen" tool to extract the sensor data?? > The java application I wrote is for the specific purpose of the experiences I made, it will be useless without the monitoring nesc application that I used. If you are interested, you can browse the code (java + dymo monitoring + sensing) at http://tymo.svn.sourceforge.net/viewvc/tymo/src/apps/tymaluate/ Let me know if you have questions, I can help you [re]using it and provide you with a zip file of the code.
