Hello,
I am seeing some problems occur with the Antitheft App when running
for a few days. I made a few slight modifications such as setting the
time interval for sending messages back to a root to every 5 minutes
and removing Dissemination as it is not needed. Would changing the
timing in this way affect the “Collection” long term? It appears to do
so since I can simply reset the node and packets start coming in
again. Another interesting fact is that some of the nodes will just
disappear for hours and then show back up some time later. (all nodes
are within a strong signal range). I think the basic question comes
down to: how reliable is the /lib/net/ctp at this point in the
development?
Any comments or help would be appreciated.
I am basically looking to get a reliable low-power multihop back to a
root.
CTP has been run for days with no mishap.
Three questions:
1) Are you on a wired testbed, or do you have nodes deployed untethered?
If the former, then you can enable CTP's debugging output (look at
TestNetwork) and examine what messages a failed node sends.
2) What platform are you using? I've heard scattered reports of the
micaZ radio stack locking up, but I think David Moss has solved this issue.
3) What version of TinyOS are you using?
