[Probably this is rfxlink related, the changes in revision r5202 moved mulle
over to using rfxlink but did not fix the local copy of rf230 files...
Notice the local copies in %T/platforms/mulle/chips/rf230 they were not
modified in the same process...]
Anyway a description on what happens
- using the apps/BaseStation to relay messages to from a PC
- sensor motes running a variant of apps/Oscilloscope
- whenever changing sample period it will change
This worked well in november (15 th)
Back to do some TinyOS work i updated svn, compiled and downloaded.
Everything looks OK. Samples are received from sensors.
But when trying to change parameters (sample period) only the first
modification works.
After a reset of BaseStation one more change works...
Got a clue when noticing that the red led was flashing fast on the
BaseStation...
Some kind of error? Searched the sources and found some questionable code.
Whenever sendDone does not indicate SUCCESS the message remains in the queue
and is immediately retried.
Modifying this to only failBlink and always go on in the queue is a work around.
(More correct would be to not remove when EAGAIN)
Note: the message did get through as the parameter change is reported back
correctly!

With this modification the BaseStation now works again.
Reverted to r5158, applied my mulle specific patches - that old version works
too (without this patch)
Miklos could you try this test case (without the patch) - if it works for you I
would suspect the mulle platform local rf230 copy...
