This is the good way to check, 1st time blinking led experience is magic ;) but I think simpleserver is not that simple for that.
So I've made simplEST servers to expose single binary switch resource and shared some hints for this check links from this page: https://blogs.s-osg.org/get-started-iotivity-interactions-artik10-tizen/ (...) >> However, I met a problem: undefined reference to 'digitalWrite' when >> Linking.

Try to make a simple program, without iotivity, on issue show us full log of build. >> Can any one help me ? >> Zhai Well, first let me suggest to build examples outside of iotivity source tree. For that I shared some sample projects you can use as skeleton to start with: http://git.s-osg.org/iotivity-example/plain/README.md For dealing with GPIOs, let me suggest to try libmraa, it does the hw abstraction and make your program portable, feel free to fork: https://github.com/TizenTeam/iotivity-example/tree/sandbox/pcoval/mraa Or you can also also fallback to sysfs too: https://github.com/TizenTeam/iotivity-example/blob/sandbox/pcoval/gpio/ Hope this will save you time. -- mailto:[email protected] gpg:0x467094BC https://blogs.s-osg.org/author/pcoval/ _______________________________________________ iotivity-dev mailing list [email protected] https://lists.iotivity.org/mailman/listinfo/iotivity-dev
