Re: [Tinyos-help] help a question about the signal strength and transmission distance

hi.rssi and link physical distance are related in a complex way. It depends on the absortion of microwaves in the enviroment. http://www.cs.berkeley.edu/~kamin/pubs/whitehouse02calamari.pdfAs far as TOSSIM is concerned I don't think power setting and received strength are implemented, so simul

[Tinyos-help] oscilloscope packets

Hi everyone. We need to understand detailed radio packet structure coming from ListenRaw.We're using the Oscilloscope app in the motes and get the following sequences:  7E 42 1C 01 08 2C FF FF FF FF A1 7D 5D 02 00 02 01 FF FF FF FF FF FF FF FF FF FF 00 00 00 00 FF FF 01 00 00 00 00 00 06 00

[Tinyos-help] power consumption!

Hieu:some mote radios (802.15.4) has a clear channel assesment (CCA) function build in used to handle collisions... they implement a CSMA-CA protocol that will back off  if signal strength overcome a configurable threshold  in the tuned frequency ...and retry to transmit later. Thus the same mechan

[Tinyos-help] deluge packets from oscilloscope?

hi all.thanks for replies on this thread. Interesting enough.. we're only programming the mote with moteiv oscilloscopeand we getting packets like this:  >7E 42 1C 01 08 2C FF FF FF FF A1 7D 5D 02 00 02 01 FF FF FF FF FF FF FF FF >FF FF 00 00 00 00 FF FF 01 00 00 00 00 00 06 00 DC 42 7E 7E 00 00>

[Tinyos-help] Deluge in Oscilloscope

Hello everyone.reading throgh the changelog... for boomerang 2.0.3 (released 07 aug 2006) it says "oscilloscope application now include deluge" i don't get it.i'm sure to have installed v2.02 (from cd)the motes programmed with oscilloscope are sending "A1" AM type packets with lenght 1Cwhere are c

[Tinyos-help] J2ME, anyone?

Hi. any chance someone here has thought or worked on porting part of the java tools to microedition (J2ME). i just search past archives on the list with no luck. thanks, Claro.     ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://

Re: [Tinyos-help] J2ME, anyone?

Thanks Robert, I'm aware of the SunSpot, however we are more interested in having the java tools from tinyos in a J2ME system... like in a gateway ...without graphic classes.   there are several hi performance embedded java platforms out there that would make a nice gateway, low power and much le

Re: [Tinyos-help] Help for generating .csv file

Vamsee,you would be better off by simply using oscilloscope.class to create a log file. you'd modify save_data() in GraphPanel.java to accommodate the format you want. then maybe automate the process that is originally manual. depending on how much you need to modify the code on the mote, you might

[Tinyos-help] current-voltage issue

dear daniele:if you want to get rid of all these constrains you might go for a charge tranfer voltage regulator (i.e. from maxim). they are efficient and for low current stable enough. you might still desire to turn it off when not necesary to further save battery life. we have not used in wsn app

[Tinyos-help] Dallas 1 wire support

hi all. note the tmote mini (just released) has 1-wire.. so is reasonable to assume boomerang support it or will do so anytime soon :D the specs here: http://www.moteiv.com/products/docs/Tmote_Mini_Datasheet.pdf are just a bit camped, though. having (or porting) a functional API implementation

Frabrizio:did you sorted out the FTDI drivers correctly?remember there is a serial<->USB interface on the Tmote.the drivers are probably part of the kernel and the motelist output make me guess you did. but, besides, the javacomm, in linux uses the RXTX. You might be willing to check:http://wass.
