[Tinyos-help] Problem when using PoolC

[behnaz.bostanipour at epfl.ch]

Hi,
I just checked and the pool is empty.
After I tried to check the size and maxSize of
the pool before and after get as below:

maxSizeBeforeGet=call SendPool.maxSize();
sizeBeforeGet=call SendPool.size();
newmsg = call SendPool.get();
maxSizeAfterGet=call SendPool.maxSize();
sizeAfterGet=call SendPool.size();
post sendDataToSerial();

And the value of all these fields is zero all the time .
Any ideas?
Thanks,
B.
