Generally, yes. As ETX increases lossses also increase. I can observe the
fact that

But, only a few times this does not hold with packets getting through
although ETX remains at a
Hi Urs,
I used a testbed of 15 IRIS sensor nodes which are placed in communication
range of the reference broadcaster. I constructed a line topology by
configuring each node such that it will accept incoming messages from the
nodes with id one more or one less of the id of the current node.
Hi Janos,
In fact I have developed another time synchronization protocol and I have
tested it using the same testbed. I can get 2-3 miroseconds accuracy. Thus,
I feel that the timestamping mechanism works well (but just a feeling :)). I
just suspect about if some modification to TimeSyncP is
In order to get this behaviour i simply added a few lines of code to my
application:
module /**/ {
uses {
//...
interface CC1000Control as RadioStrengthControl;
//...
}
}
and
event void Boot.booted() {
//...
#ifdef RFPOWER
call RadioStrengthControl.setRFPower(RFPOWER);
#endif
//..
}

Hi Urs,
thank you for your clues.
I copied the lib/serial files to my test project folder.
Now I can receive single bytes and can follow the state machine step by step in
the SerialP.nc file. If I send single bytes 0x7E (Framing byte) and 0x44 (Frame
Type) the state machine accepts the frame
Hi Urs,
again, I reduced the baud rate to 38400 now it works. The module receives a
whole frame and sends an ACK frame. Now I have to find out why the highest
event in my test code is not called.
For now thank you for your help.
Cheers,
Mario

Hi guys,
Has anyone ever actually successfully worked with XML RPCs to XServe? I have
XServe running fine, and I'm able to use XServeTerm without any issues.. but
all I'm reading about is lots of documentation on XServe, and a lack of
actual working implementations.
For the moment, all I want to
Hi Urs,
the official baud rate is 57600 but the AVR ATMega1281 on my platform
(Meshbean) should use double rate for the UART but the controller does not use
double rate even though the flag is set (should be set??). I think the accuracy
at 57600 is not high enough. Using the baud rate 38400
Hi Mario,
The default event is indeed only called if no wiring has been specified.
This could have two reasons: (1) you have a wiring problem (as you
suggested), or (2) or the type of the message (the value in the square
brackets [] before the function parameters) is not the expected value.
Hi all,
is there any simple method of erasing the log on the node NOT from the code
itself? E.g. when installing a new program?

From my experience with deluge, if you opt for 'disseminate and reboot'
option, the program gets disseminated and all the nodes now reboot with
this code. You can verify this by ping command and find the name in the

Are you using TestNetworkLpl and changing the flags in the Makefile to

Hi,
I just switched to the Tinyos on Google Code. It seems that the

from other nodes.
It seems the problem is that sendDone() is never triggered on a node who is not
root.

Hi Jingyao,
I use Tinyos-2.0.2... You will have to make changes to some files in
micaz for making it work.
Please also send your questions to tinyos-help as there might be other
people also who can answer the questions.
