[Tinyos-help] Problem with Netsync, restarting motes.

Hi,

I'm using tinyos 2.0.4 from Moteiv and the netsync component to get
synchronized time information when i'm sampling data. I have changed the
dutycycle to 100%
LOWPOWER ?= 100 in the file lowpower.extra
to get a higher data rate on the radio. (Is this a  correct way to get
higher data rate with sync?)

My problem is that it takes 3-5 (or more) minutes before the slave nodes
have a stable sync to the master node. The startup time is not a big
problem but during that time the slave nodes are restarting (?). It
seems like they get a reset? The StdControl.init() function is executed.
And it also happens that the slave nodes drops the sync, 10-30 minutes
after it has stabilized, and the procedure must start all over again.

Is this normal?

/Henric
