Wrapping the OTSndUData() with DCon dprintf's, and putting dprintfs in the
OTNotifier, I would have expected a trace like:
Before OTSndUData()
Inside OTNotifier() - got T_DATA
After OTSndUData()
but I don't.. sometimes the "Inside OTNotifier()" is after many other OT calls
and in our case, too darn late.
What execution context are these OTSndUData calls being executed in?
Are they running at system task time?
Have you checked to make sure that the T_DATA isn't being held off by
another notification? If the destination endpoint's notifier is
already running, OT will not reenter it to delivered a T_DATA.
In the destination endpoint's notifier, do you keep calling
OTRcvUData until all the data has been received (ie you get a
kOTNoDataErr)? If not, OT will assume that the receive side is flow
controlled and not send you another T_DATA until you complete the
existing read.
