Try to use longer times and observe if the problem persists.

It probably is related to hardware limitations.

The tinyos.jar file seems to be OK in the CVS:
http://tinyos.cvs.sourceforge.net/viewvc/*checkout*/tinyos/tinyos-2.x/support/sdk/java/tinyos.jar?revision=1.12

Can you compare yours with the one above? If they aren't identical, please let me know where the bad file came from (i.e. what method you used to install tinyos), so that we know what to fix.

Hi,

I want to use the GPS module of MTS420CA with MICAz on TinyOS 1.1.15. Is there existing driver for this module in the community? I wonder if anyone had previous experience on getting GPS data from MTS420CA and could give me some help.

Thanks a lot!

Regards,

Qi

Hello all,
I have made my own application called "Routing" in which I am trying to change the default MAC protocol used in TOSSIM (which is CSMA). I have modified the file TossimPacketModelC.nc a bit and some interfaces too it. The application compiles fine as is shown by the output of make below:

However, while trying to run the simulation using python test.py (which only contains the line (from TOSSIM import *), I get the following error. I tried to search the Tinyos help list and found a similar problem faced by someone before but I couldn't find a solution posted to it.

%%%%%%%%%%%%%%%%%%
bash-3.2$ python test.py
Traceback (most recent call last):

    import _TOSSIM
ImportError: /opt/tinyos-2.x/apps/Routing/_TOSSIMmodule.so: undefined symbol: send_csma_sample_channel

Any help in this regard is appreciated.
Thanks,
HS.

I am trying to write and read some ram data via SPI, and also perform some basic command such as SNOP to get the status of SPI.
But what I read from the SPI are all 0xFF, and the status of SPI is always 0xFF.
I have used the Resource interface to gain the access of SPI and pull down the CSN, just as follows:
