Yes, it's normal. You see the effect of two unsynchronised clocks here, the TDMA master's clock driving the cycle and the slave node's local clock driving the sender task. > How can I optimize this? You can stabilise this drift by synchronising the slave application on the TDMA cycle. See http://www.rts.uni-hannover.de/rtnet/lxr/source/examples/xenomai/native/tdma-api.c Or you can improve the chances for the master and the slave to communicate, either by raising the TDMA cycle frequency or by scheduling more TDMA slots per cycle (of course, reasonably distributed over the cycle period). See TDMA documentation, specifically on joint slots. Jan
