Re: [Tinyos-help] Low power listening
Which sources are you using? Boomerang allows you to change the duty cycle via the lowpower parameter of make. The NETSYNC_PERIOD_LOG2 macro allows you to change the time between listening periods by default NETSYNC_PERIOD_LOG2 is 16 i.e. 2**16 ticks of the 32khz clock is 2 seconds. Default lowpower is 5% . 5% of 2 seconds is 100msecs. So by default you listen for 100msecs every 2 seconds. Suppose I want 100sec every 4 seconds, set NETSYNC_PERIOD_LOG2 to 17 ( 4 seconds) and lowpower to 3 (3% of 4 seconds = 120msec) Add the following line to your makefile ifeq ($(filter netsync_period_log2,$(MAKECMDGOALS)),netsync_period_log2) then do make platform lowpower,3 netsync_period_log2,17___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Deluge 2.0 supporting heterogeneous networks
Can I do something like this. Instead of using the java toolchain from Deluge for rebooting, create my own command and send it through BcastInject to the mote. This command will have the nodeid and the image number to reboot with. When the nodes recieve this command, they check whether the nodeid matches their TOS_LOCAL_ADDRESS. If it does they would call the NetProg.reboot command , otherwise ignore the message. Any guidance would be appreciated I'm planning to do something similar in my tinyos 2.x application. I don't know if it will help you, but here is my plan: 1) Each app on the network reserves a deluge slot for themselves (app 1 'owns' slot 1, app 2 owns slot 2, etc. slot 0 is for the golden image). 2) Use the python tos-deluge script (not the java tool) to disseminate updated images over the network. Just disseminate, *not* reprogram. 3) This is the magic part - apps on the motes monitor Deluge and wait for their dedicated slot to be (completely) updated to a new image. Then they reboot themselves into the updated image. (3) will probably require Deluge interface updates. Probably in the form of a new Deluge interface and a set of events your app can respond to. Razvan might add this when he has time (we've discussed it off-list), otherwise I'll add it my self later when I need it. David.

Re: [Tinyos-help] RSSI code
At first I'm sorry for interrupting. Can some one provide me the code to get
the RSSI value for CC2430 mote? and I'm using tinyos-2.x. Please help me.
Thanks for your help.
As far as I know, you can either get a background RSSI value, or RSSI
values for individual received packets. I assume you mean the latter.
Here is how I do it in one of my apps:
# In your public module:
implementation {
components CC2420ActiveMessageC as CC2420;
YourPrivateModuleP.CC2420Packet - CC2420;
/* Also wire up your Receive interface etc here */
}
# In your private module:
module PrivateModuleP {
uses interface CC2420Packet;
}
# Inside your Receive.receive event handler:
uint8_t raw_rssi = call CC2420Packet.getRssi(bufPtr);
/* And here is how you convert to a human-understandable rssi value */
/* From this post:
http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2006-April/016081.html
*/
/* - First convert from 2's complement */
int16_t rssi = raw_rssi;
if (rssi = 128) rssi -= 256;
/* - Now subtract the RSSI_OFFSET */
rssi -= 45; /* rssi now contains a human-understandable RSSI in dBm. */

[Tinyos-help] Resource.reserve returns EBUSY forever after some time
Hi
I am using MultiChannel sampling on the msp430 ADC as shown in
tinyos-2.x/apps/tests/msp430/Adc12. When I run the program, it runs correctly
for a non-deterministic length of time (sometimes minutes, sometimes a day) and
then appears to be stuck. Debugging with LEDs and UART shows that the timer for
sampling continues to fire, but the Resource.reserve call returns an EBUSY
error type after this time and no more granted events are signalled.
Also, there's no other ADC client in my application. I only use the timer, UART
and this ADC getData call. The MultiChannel interface is wired to the
Msp430Adc12ClientAutoRVGC component. I've seen this happen for sampling rates
of 1kHz down to 167 Hz, but haven't tested for lower sampling rates.
The code I am using looks like this
event Timer.fired(){ // this fires every 6ms
result = call Resource.request();// returns SUCCESS upto some
non-deterministic time, during which Resource is granted and I can read ADC
correctly, after which always returns EBUSY, no more Resource.granted events
are signalled
}
task void releaseResource(){
call Resource.release();
}
task void processData(){
.. send samples to UART
}
event Resource.granted(){
if (MultiChannel.configure(config, memCtl, 1, buffer, BUFFER_SIZE, 0) ==
SUCCESS)
if (call MultiChannel.getData() != SUCCESS)
post releaseResource();
else
post releaseResource();
}
event MultiChannel.dataReady(bufptr){
call Resource.release();
...make local copy;
post processData();
}
If anyone has observed this or notices something I'm doing wrong, please let me
know.

[Tinyos-help] Corr value
Hi all, I am emulating cc2420 radio chip in avrora and testing it with tinyos-2.x. Right now, I am working with LQI and RSSI values. However, I don't have idea of how to simulate the correlation value. In the data sheet says that this value can be seen like a chip error rate. So, I was thinking about using the S/N and then the BER to calculate that, but, I don't understand why it ranges between 50 and 110. Do you have any idea of how to model that?

Re: [Tinyos-help] Resource.reserve returns EBUSY forever after some time
Maybe I'm not programming in the spirit of tinyos, but I don't ever call
resource release under normal circumstances. I certainly see no reason
to do it in code where there is only one place where sampling is done and
the sample rate is fairly high.
Your code looks like it should work, but it is complex enough that I
could be wrong.
I think if you reduce your sample period by a factor of 10, it should work.

If you're using mica2 and tinyos-1.x, it is very easy. You can read RSSI
