If the D2 light is the red one, then it probably means that your batteries are low. When the batteries on my Mica2 motes run low, the red light flashes and they act unreliably (read: unable to program them, and the radios work only sporadically).

Is it possible to run multiple copies of TOSSIM (one for each application under test) connected to one serialforwarder so that they can talk to each other?

Sometimes, under WinXP, I have to use something like Hyperterminal to
initially open and close the COM port to which the MIB510 is attached
before programs under Cygwin can do it. It might just be my
laptop, though.

The documentation for TinyOS says that interrupts are DISABLED within "atomic" sections of code, such that no asynchronous will even occur, since asynchronous events are generated by interrupts. - Conor

Are you able to use your serial port at all under Cygwin?I've found that using something like Hyperterminal to open and close the COM port under Windows before trying to use it in Cygwin clears up any problems.
As for USB-Serial adapters, I haven't had any luck with them. - ConorOn 7/18/06, r
Hi Alexandre. No worries about asking questions -- we're all novices at some point!
In TinyOS, a read from a sensor is generally split into two phases: the
request, and the read. You make the request for a reading from
your ADC (or whatever the sensor's connected to) and then go off and do

Hi. I'm writing a bit of Java code to run on a PC connected to mote network. I'm currently using TinyOS-1.x, but at some point I'm sure I'll move to TinyOS-2.x. For my java code, should I connect to a Serial Forwarder to receive packets, or should I use MoteIF to connect directly?

Are you using any sort of scaling factor when reading the temperature,
or is PhotoTemp giving it to you as a raw voltage reading? If the
latter is the case, you'll need to scale it Celcius degrees.

Perhaps if you use the QueuedReceive mechanism, you'll not loose as many packets? Or, if you really want to be sure you're getting the packets and you don't want to touch the radio stack, try using the RadioCoordinator interface, which allows you to be notified every time a byte is recieved.
If I understand what you're doing correctly, then the problem may be in the book-keeping. If the RF channel is in use and your mote tries to send, that send is going to fail, and you're never going to get a RadioCoordinator event (because there is no sending going on). Therefore, your handler for

I completely agree with you on the lack of respect for documentation's role in software development. Much like in a math proof or a professional chef's recipe, many important steps and assumptions are not documented because it's assumed that whoever's looking at the code can understand it triviall
I get this sometimes. Sometimes it's just low battery voltage, sometimes it has to do with Cygwin not being able to get full sense of the COM ports, and sometimes it's because there's a stale copy of UISP running in the background which needs to get killed.

Interrupts are disabled within async{} blocks. Therefore, no events can be fired, and nothing will happen except for what's in your async code (unless the batteries die or your mote falls into a pool of molten lava).

No. The only way to break out of the async nature of interrupt handlers (and functions called by them) is to post a task, thus allowing the synchronous interrupt-handling call tree to terminate. - C

Unless you specifically enable interrupts inside of an atomic section (I'm not even sure why you'd want to do such a thing), then no interrupts will occur because they are disabled within atomic sections. - Conor

Perhaps you need to pass different strings to unique() in order to get different values out of it? What I am implying is that all three of the timers you wire below may resolve to the same timer because you give them all the same name.
