Attach the trace file again.
50 ms / 2 ms is still too large for this trace. You see that the trace is only able to cover ~40 ms. So, use a 2 ms cycle with, say, 500 us offset. > >>> Try to leave that TDMA-less demo running for a longer while, or run it at > a comparable ping rate.

OK, I'm believing now. :) Jan
