as far as lower powers, specifically). Does anyone know for sure or have
any experience with the explicit transmission power levels on the CC2420?

Does anyone know of a package that provides link-layer
encryption for the micaz motes? I think tinysec would
be perfect, unfortunately, I read that it's only supported
on mica2 motes and all I can work with right now are the
micaz'.

for simulation,
you might as well just run it on the motes [I think make pc includes
the default AM.h file, not the ones containing lqi, therefore you
wouldn't be able to get the LQI anyway (maybe)]

does not change, and when I move the motes closer, the values get
closer to 0xFF and while I move them apart, they fall down to around
0xD2 before failing to receive packets at all.

value and the signal reading don't make much
sense at this point.
Does anyone know a way to accurately determine the signal strength
of incoming RF packets to a micaz mote, while fixing the problem
above?
Thanks,

I know the 22, 23, 24 is the data portion, so ListenRaw or
the serial port must be cutting something off from the beginning.
It appears as though the strength is registered as 0 though.
Does anyone know of a better approach?

Out of curiousity, this is related to a problem I had today...
are these rewritten packets changed as far as received
signal strength goes? As I said in a previous email, the
micaz AM.h file declares TOS_Msg-strength as uint8_t
and regular AM.h is uint16_t. Now my micaz messages

Hey guys,
I'm trying to fix this program I'm writing, I think it is just a minor
problem. In the program, I send a message each time a timer
firers. I introduce the SendMsg interface like this:
uses {
interface SendMsg as SendIntMsg;
...
}
and then I send my message like this:
read it was a component that
provides the SendMsg interface, but again I'm having trouble with it.
Thanks

Hey guys
I was curious about a strange warning I received when
I compiled a program involving the micaz radio stack:
C:/tinyos/snip/tos/lib/CC2420Radio/CC2420RadioM.nc:115: warning:
`Send.sendDone' called asynchronously from 'sendFailed'
The relevent snippet is:
void sendFailed() {

tos/platform/mica2
tos/lib/CC2420 (for micaz)
Make sure that the components in these directories precede the
corresponding ones from the official tinyos release in your search path.

I know there is a testing application that verifies the accuracy
of the FTSP algorithm for mica2/micaz networks. Is there a
codebase which I can simply insert into my existing application
so that it would synchronize itself upon startup? Or is it not
that easy?
Thanks,
I tried all of the following suggestions, and the same problem arises.
I installed tinyos 1.1.11 because I had the install shield version and
it seems to be much cleaner than installing 1.1.0 and then upgrading
via RPM to 1.1.10. I could only find the January cvs release of 1.1.10.

I've been sort of stuck on this after trying a lot of different things.
I have an MIB510 board and a few micaz motes. I connect the
board to this laptop through the serial port. I've successfully
uploaded binaries to mica2's in the past.
Now I've tried on tinyos 1.1.10, 1.1.11, and the latest
programmer (I had worked with the parallel programmer before with mica's).
The MIB510=COM1 command is apparently case-sensitive. Please try that.
Could work.
MIB510=COM1 make mica2 install(/reinstall)

I know you can retrieve the signal strength of an incoming packet

to a java program through TOSBase, is it possible to use the

of said packet? Thanks,

a compiler-time error, saying CC1000Control.SetRFPower not connected.
I can only assume that I have not wired something correctly, but I don't
