Hello,
If a TMote / Telos is plugged into a USB port, 3V appears on U4 - the battery
holder connection. If batteries (particularly disposables) are installed, is
this going to cause a problem? If the batteries are partially exhausted then
there's a danger of a reverse current presumably?
Hi,
Im wondering if anybody knows a proper formula to convert micaz's RSSI
values to dB? (I guess 255 is 0dB, isnt it?)
Thanks in advance

See the CC2420 data sheet.
The RSSI value is a 2's complement number with an offset of -4?, I
can't recall if it's -45 or -42.

from tinyos.tossim.TossimApp import *
I get an error from the python interpreter:
ImportError: No module named tinyos.tossim.TossimApp

Hi,
I am performing data mining experiments on the sensor network data.
Can anyone give me links to web pages which have datasets collected
during experiments?
Here are few links which I already know about:

thanks, just checked, it is -45. this means that 255 = -1-45=-46 dB
and 245 = -56 dB for example, isnt it?
Yes. Note, though, that it's *approximately* -45. If you want really
precise measurements, ChipCon recommends calibration to
After update the whole tinyos 2.x in October, using the develop branch, the apps/BaseStation does not work. In particular, using a Java program to open and write a message to the BaseStation via serial port will return error. While the same code can run on the previous version of tinyos.
