Hi Ravi,
Thanks very much for that. I'll try it now. Looking briefly at the code, I
think the key may be the use of the interface SplitControl, which I wasn't
aware of before. I think that should be a better way of handling turning the
radio on and off.
Once I've played around, I'll post my f
Hi Andrew,
Thanks for the pointer to moteiv. I downloaded their tool chain and want to
check it out. If it looks good I will consider their product. The Korean motes
also look good.
Thanks to all listers who responded.
Cheers,
Ken

Well, I've had some success. Basically I've used SplitControl to wire directly
to CC2420RadioC (whilst keeping all the GenericComm stuff in place to handle
the messages). Then I use this type of thing:
event result_t Timer.fired() {
SPACER = !SPACER;
if (!RADIO_ON && !SPACER) {
call L
Hi,
I'm trying to build an aggregation tree using the collection component in
TinyOS 2.0 wherein nodes sense temperature values periodically and send it
towards the base station and certain amount of in-network processing is to
be performed. We're having micaZ motes and use the MTS 300 sensor boa
Hello everyone.
In CC2420 data sheet. it specifies the high sensitivity (-95dBm).
Received power in cc2420 can be drived from RSSI value. (P = RSSI + Offset
(-45dB))
The minimum RSSI value was -49dBm in my experiment. Therefore received power
-94dBm was the minimum power in Tmote Sky.
Can i co

Some days before I used to obtain the same error as yours, but now I can

and many redefinition warnings.
Yes, you can compare these powers directly. The sensitivity threshold
is -95 dBm, and consequently CC2420 will not report RSSI below that
threshold. The RSSI reported is the absolute measure of the energy
in the incoming signal; you can access RSSI when there is no packet
being received, and the

I see that Crossbow sells them. However, they appear to have a licensed tool
chain. I assume the tinyOS code and tool chain works just fine on them and that

Hi,
I'm working on a multi-channel MAC project in tinyos-2.x. Could anyone
please tell me if I can use TOSSIM to simulate a network with motes
work on more than one channel.
Any suggestion would be very appreciated.
Thanks,

Hi,
I want to measure absolute pressure between 0-15PSI. I want to know where can I
get a pressure sensor which gives output within the input range of tmote sky
and also I am not clear whether to give different power supply to sensor or the
same as tmote sky.
Does the Vref of the ADC of tmote sk
Thanks you for your advices.
We want to derive a accurate SINR of incoming packet.
Then, can i understand that received signal power in cc2420 data sheet means
the SINR of incoming packet?
It seems after we consider the offset value (-45dB) it provides the
SINR from RSSI value.
Moreover, if we st

Free keeps track of how many elements are in the pool. As in "free
elements that other components can allocate." So when you initialize the
pool, all of i

I use blockstorage interface and I use BlockWrite and BlockRead to write and
