[Tinyos-help] LocalTimeTMilli on TelosB skips back

2012-03-21 Thread Alex Koay
I've been collecting data with TelosB motes for the past few days, and when I started to analyse the data, I found some weird points where calling LocalTime.get() would return values about ~1 earlier. Has anybody experienced this before, and is this an expected behaviour? I've been relying on

Dear all, I downloaded from sourceforge all the minitasks\02\vu\ CVS folder to try the AcousticLocalization application of ISIS Vanderbilt University. I have put the folder vu in : cygwin\opt\tinyos-1.x\contrib\vu\ and I have set the environment variable VUTOS as explained in the ReadMe file

Giacomo: The code in contrib/vu/apps/AcousticLocalization does compile for mica2. If you need to get it work on another platform, you'll have to figure how the makefiles need to be adapted to include the required interfaces. Please note that this code was written 10 years ago, that is, it

[Tinyos-help] CTP_OPT_ECN in CTP

Hi, I am a bit confuse. I am not really clear how a call to CtpInfo.setNeighborCongested(from, congested) can set the neighbor as congested (in the BeaconReceive.receive() event in CtpRoutingEngineP)?, because I found that a call to CtpRoutingPacket.getOption(msg, CTP_OPT_ECN) returns FALSE,

To get to the actual TOS release for the nescc builds under T1, I think what you need is something like this in your environment (on Windows): # Set main pointers used by TOS build system to find files # TOSROOT is for external programs, TOSDIR for makefiles TV=tinyos-1.x ## I use this to select

[Tinyos-help] RF230 HW ACK: Driver uses undefined state transition RX_AACK_ON - TX_ARET_ON?

2012-03-21 Thread Markus Jung
Hello, hardware-acknowledgements have been reported to work on real devices (AFAIK), but while trying to simulate a TOS application using HWACK with LPL, i stumbled upon following behaviour: Phase A: The driver puts the radio into RX_AACK_ON mode. All is fine until Phase B: A transmission gets

Hi Markus, On page 89 of the datasheet there is a workaround that shows that you can switch between TRX_CMD=TX_START the to TRX_CMD=RX_ON and then to TRX_CMD=TX_ARET_ON. So even in the manual they use this (at lease in one of the published workarounds of an errata). I do not know how slower the

Hi Miklos, thanks for pointing this out. I did not simulate errata and ignored them therefore - Until now. I will have to think about how i can handle this very special behaviour in my simulation. Silicon bugs suck. Regards, Markus Am 21.03.2012 23:28, schrieb Miklos Maroti: Hi Markus, On
