Hi, I'm authoring a realtime protocol and using FTSP to synchronize 25 TelosB motes. Initially, FTSP seems synchronized after I run it for about 7 mins. But after initial synchronization, sometimes call to GlobalTime.getGlobalTime() still returns FAIL, meaning the node is not synced. And the ratio of unsync can be as high as ~30% in all the calls. Has anyone met similar problem before and how can the ratio of unsync be reduced while still providing accurate global time? Thanks.
