[Tinyos-help] the value of packet-crc

Hi, I use TOSSIM as the simulator and notice some packets cant be correctly received because of the packet-crc = 0, which means crc check fails, while most other packets can be received well. I wonder why this happens when I use simple radio model and all motes use the exactly same

Re: [Tinyos-help] Delta application -help required

thanks for ur reply michael, if i sample the signal at 1ms(suppose for 50hz signal)then it will be better...that is required for my application ...one more thing is that, the system tht i want to monitor is highly dynamic in nature..so the data should be sendfor every 1ms...i think 1ms is

Re: [Tinyos-help] Delta application -help required

Hy Siva, here is a short description of the Delta application: - StdControl.start() calls the command Timer.start() to start the programm - Every time when Timer.fired() (periodically, all DELTA_TIME ms) the sensor getsthe request ADC.getData() - When the data is ready (ADC.dataReady()), the

I can't find TinyViz in the source code of tinyos 2.x... it's possible to import tinyviz from tinyos 1.x or it's simply not yet developed? (what can I use in this case?) Thanks for the answer, bye. ___ Tinyos-help mailing list

hi ole, i am very thankful to unow, i understand whats going on.. butone thing remindsthat is ---i asked abt sampling at 1ms and sending the data in tht time only...for an external ADC signal of 50 hz(say)using multihop(obvious) technique...the thing is i am losing lots of

Re: [Tinyos-help] calibrating TMote Sky sensors???

Hello, Are the batteries on both motes supplying at least 2.4V? If it falls below, the readings will be different from what they should be. The SHT11's otherwise are calibrated by Sensirion at the factory, that's why they cost what they do! Simon Davis On Tuesday 29 August 2006 09:55 am,

Re: [Tinyos-help] Delta application -help required

As I said, based on my (small) experience with micaz I believe that 100 messages per second is about the max you can expect. And that 100 is for the total system, not per mote (unless of course you have only one mote transmitting). If you are doing multihop then you need to divide the total

See, this is the problem with software education these days. There is no way to demo the documentation.. I met a lovely woman from the Univ of Chicago who was doing her dissertation on mobile routing a couple years ago, but I'm afraid that I don't have any concrete leads for you. Google is
