RE: [Tinyos-help] High Frequency Sampling - Sample.class run error

Thu, 09 Mar 2006 18:31:26 -0800

I have already managed to rectify the problem below. It was due to my MOTECOM env settings. I had it set for MicaZ so i have now changed it for Mica2. But could anyone tell me how i can disable the MOTECOM env so that i can use SerialForwarder?
 
Also, now when i run the sampling program - Sample.class, i keep getting an error that sampling has failed. On both the motes, the TOSBase and the HFS mote, the red LED lights up. Could anyone tell me what could be the possible reasons for this? I have not modified the module or interfaces in any way. The only thing that i have changed is the MAKEFILE.
 
Thanks and regards.
 
Amit.

Hi. I noticed that my mail cannot be viewed on the website so i am sending it from another e-mail address.

I have tried to run the High Frequency Program from the xbow/apps folder and i get the following error:

---------- Capture Output ----------
"C:\Program Files\Crossbow\Crimson\IDE.bat" "C:\tinyos\cygwin\opt\tinyos-1.x\contrib\xbow\apps\HighFrequencySampling2" "c:\tinyos\cygwin\bin" "java Sample 200 20000"

I am currently running this program on 2 Mica2 motes. I have installed TOSBase on one and the program on the other. When i run the command "java Sample 200 20000", i get the error as above. I have opened Serial Forwarder as instructed by the readme file. The error is that it can't find a platform specific version of TOSMsg. Could anyone tell me how to resolve this error?

Thank you and regards.

Amit.
