Hi,
I have been trying to get the Collection-example in tutorial 12 to
work without success. Problem is that the root-node doesn't receive
messages from other nodes.
I'm using Mica2 and currently I've tested with three nodes in
different roles. The hardware should be ok as the examples using
AMSender and receiver work properly.
I tried to debug by changing the sendMessage and sendDone -functions
to toggle a led whenever it sends something:
sendMessage:
else {
sendBusy = TRUE;
call Leds.led1On();
}
Send.sendDone:
sendBusy = FALSE;
call Leds.led1Off();
This way the sending node would just turn led 1 on, so my conclusion
is that the first packet never arrives at root and the other nodes
are just trying to retransmit it. The error-led doesn't light up at
any time.
I'm using
nescc: 1.2.9
gcc: i686-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc.
build 5367)
and TinyOS-build is from CVS.
When compiling, I get three "control may reach end of non-void
function ... being inlined"-warnings and four times the warning
"tos/lib/net/ctp/CtpForwardingEngineP.nc:656: warning: 'gradient' may
be used uninitialized in this function" from different lines of that
file.
I played also with the TestNetwork-example and ended up not getting
it to work either.
If anyone has experienced similar problems, I'd be glad to share
experiences. Especially with OSX-users, as it was not so easy to get
the development environment to work.
Thanks in advance and best regards,
Risto Hietala
