Thanks all for the reply...

I have taken all your comments into consideration.

This what i get when i am trying to print.It prints nothing

[Tinyos-help] Eclipse and tinyOs

[aron bengio]

Hi to all, my name is Antonio i'm a student i''ll do a tesis for my teacher and 
i''ll use telosB for read the value from a  small WSN (wireless sensor network)
now, i will create a small java application,  for read the value that sensor 
give me. 
can you give me a simple example for to undestend to create this application? 
can you know book or web site for this example?
this is a my pc for develop:  
XUbunutu 12.10
tinyos-2.1.1
eclipse indico relase 2

excuse me for my bad english

[Tinyos-help] To store some of the received information in the local node module

[Swetha]

I need to store some of the received information in the local node module 
before broadcasting it.




implementation{
  message_t pkt;  to hold data for transmitting  the packet 
  message_t store; /// to hold data for storing in local node module





 event message_t* rreqreceiver.receive(message_t* msg, void* payload, uint8_t 
len)  {


   RouteDiscovery_t *rd_msg = (RouteDiscovery_t*) payload;


   RouteDiscovery_t *r_req = (RouteDiscovery_t*)(call  Packet.getPayload(&pkt,  
sizeof 
   (RouteDiscovery_t)));
   r_req->nodeid=rd_msg->source;
  /// codes to send packet (&pkt)




/// Here is my doubt, is this good way to store the received message 
information in the local node module or is  there any other approach to store 
the received message 




  NodeCache_t *cache = (NodeCache_t*)(call  Packet.getPayload(&store,  sizeof 
(NodeCache_t))); 



cache->route=rd_msg=route_id;

[Tinyos-help] CC2420X stack crash

[Xiaohui Liu]

Hi everyone,

I'm using CC2420X stack to deliver unicast traffic over 100 links. Every
sender transmits with a period of 100 ms. Around 10% of the nodes crash
within 3 minutes. I have witnessed similar
issue
before,
don't know if they are related. No node crashes if CC2420 stack is
used. Does anyone encounter this problem using CC2420X? Please do not
hesitate to share any thought. Thank you.

Re: [Tinyos-help] CC2420X stack crash

[Janos Sallai]

Xiaohui:

I have not seen this issue. Can you verify that RadioCountToLeds
works? It's essentially the same application that you describe, with
250ms delay instead of 100ms in your case.

Can you put together a simple application that demonstrates this
"freezing" behavior? I'd be more than happy to take a look at it.

Re: [Tinyos-help] CC2420X stack crash

[Xiaohui Liu]

Hi Janos,

I tried the default RadioCountToLeds with cc2420x, with only the following
changes. Within 3 minutes, about 10% of nodes stop toggling led 2 and
crash. If MilliTimer fires every 100 ms, about 30% of nodes crash.

*  event void MilliTimer.fired() {*
*counter++;*
*call Leds.led2Toggle();*
*...*
*}*
*  event message_t* Receive.receive(message_t* bufPtr, *
*   void* payload, uint8_t len) {*
*dbg("RadioCountToLedsC", "Received packet of length %hhu.\n", len);*
*if (len != sizeof(radio_count_msg_t)) {return bufPtr;}*
*else {*
*//  radio_count_msg_t* rcm = (radio_count_msg_t*)payload;*
*//  if (rcm->counter & 0x1) {*
*// call Leds.led0On();*
*//  }*
*//  else {*
*// call Leds.led0Off();*
*//  }*
*//  if (rcm->counter & 0x2) {*
*// call Leds.led1On();*
*//  }*
*//  else {*
*// call Leds.led1Off();*
*//  }*
*//  if (rcm->counter & 0x4) {*
*// call Leds.led2On();*
*//  }*
*//  else {*
*// call Leds.led2Off();*
*//  }*
*  return bufPtr;*
*}*
*  }*

Please let me know if you have any idea what may go wrong. Thanks for your
reply.

[Tinyos-help] how Many Telosb/z1 nodes can be serially connected to one PC!

[wasif masood]

Dear All,

Does any of you have ever experienced about how many sensor nodes we can
attach to a PC. In my experience, using external powered USB hubs, one can
get as many connections as could but when it comes to serial logging, not
all the nodes can get their data to the BaseStation via serial connection.
Yesterday, I tired upto 10 and they worked just fine, but if I try to
increase them beyond 10 some nodes just meteriously can't log any thing.

Please share your experieces!
Regards!

[Michael Schippling]

I have a vague memory that there was a problem
getting more than 16 serial COM ports under Windows,
and in some cases the device numbers kept incrementing
even though devices were not attached...

it's been a while since I tried though.
