Hi,
Why not just generate a random number with the Random interface and then
initialize a timer with this value?

Hi,
Why not just use a moteID for every node?
Node 1 only addresses to 2. Node 2 upon receiving from node 1 addresses to 3,
and so on.

Hello,
Sleep mode and always receiving doesn't really fit together...
Easiest way is to use LPL.

Hi all,
I have a question regarding the CC2420 and CCAs.
When attempting to transmit a packet, when and how many CCAs are done?
Is this correct?
Initial backoff - CCA- TX or congestion backoff
Or is there first a software CCA and then a HW CCA from the CC2420 itself?
regards and
the tutorial on the tinyos website about printf is very clear about this subject
good luck

Hi all,
I have been thinking about this for a very long time, but couldn't formulate an
answer, so I ask my question to this community:
My application exists of 41 telosbmotes, 40 of them send 1 request (20 bytes)
at a random time in every 1-second interval to the 41sth mote who functions as
advantage of the periodes in which the Radio not sending or receiving but
without turning it off.
how can I work around this if it's not possible
Thanks Have a Nice Day

Hi,
Once you call splitcontrol().start and the splitcontrol.startdone event is
signalled, the radio stays on. If you send something, the radio goes into TX
and after the sentdone is signalled it goes back to Listen, but if you don't
send something it stays in Listen-mode,
unless you call

Why is the current consumption with the radio off this high (2mA)? I only have

Can I get this any lower?

Did you change the message format in the header file?
I'm sending arrays without any problems.
I have this in my app header file:

Hi,
I think there must be a hardware-limit on the packet size.

My thesis mainly is about WSN and energy harvesting.

Another think i can't figure out is the unit of this parameter.
The RadioBackoff interface says: the amount of time in some unspecified units.
What defines this unit and what are the boundary values?
