[Tinyos-help] Problem with TinyECC ecc.h and Eclipse / Yeti2 plugin

2010-10-29 Thread Markus Niedermann


Hi,
I want to use TinyECC in Eclipse.
Where do I have to include the TinyECC-Folder that I can use it correctly?

I included it in the run configurations, in the global tinyOS-Settings 
and in the project preferences.
the plugin finds the files from ECC, but it throws me errors in ECC.h 
which i included in the first row.

the error is:
(in included file; see ECC.h: 72) data object declaration: expected a 
'field declarations', common
 missing tokens at this place: '}', to complete expression, insert one 
of: '}', 'typedef', 'extern', 'static',
 'auto', 'register', 'void', 'char', 'short', 'int', 'long', 'float', 
'double', 'signed', 'unsigned', '_BOOL',
 '_Complex', 'struct', 'union', 'enum', 'const', 'restrict', 
'volatile', 'inline', 'default', 'nx_struct',

 'nx_union', 'command', 'event', 'async', 'norace', 'task', 'typedef name'

This error is dislpayed for other rows in ECC.h, too.
When I open ECC.h, there is no error showen.
I attached the ECC.h and the in ECC.h included NN.h

Thanks for your help!

Re: [Tinyos-help] Broadcast packet not received by all motes

2010-10-29 Thread Yong, Chee Yeew

Unless you have some randomisation before you transmit packets, sounds like
your packets are interfering with each other. SendDone can be signaled even
if packet's lost in propagation (I think..).

 Subject: [Tinyos-help] Broadcast packet not received by all motes

 Hi,

 I'm implementing a simple message exchange between two motes 
 (to measure 
 the RSSI, but this is not of interest) and
 send the messages as broadcasts.
 I'm using the TinyOS Basestation application with the Listen-Tool to 
 check which messages have been sent.
 Here's the problem: I have two motes (call them A and B) with nearly 
 identical code flashed to them.
 A sends a message (broadcast), and after that each mote will 
 send a new 
 broadcast after receiving a packet.
 All messages sent by A are also received, and thus displayed, by the 
 BaseStation-mote, and the LEDs indicate that
 all messages are also received by B [otherwise only one 
 message would be 
 sent anyway].
 But, when B sends a message, it seems to be received by A [as 
 A responds 
 with yet another packet], but is not displayed
 by the BaseStation-App. I tried to verify this by flashing a 
 third mote 
 with custom code, same issue.
 If I just call the SendProbe-method [see below] on mote B it 
 works fine 
 and switching motes doesn't help either.
 LEDs suggest that the SendDone-Event is triggered on both motes.
 Ultimately, it seems that the broadcasts are only received by 
 the mote 
 from which the last message was received (?).
 Is there any property of broadcasts that I am not aware of?
 Here is the (relevant) code I use:

  void SendProbe(){
  probe = (ProbeMsg*)(call Packet.getPayload(pkt,NULL));
  probe-source = 1;
  probe-counter = counter;
  call AMSend.send(AM_BROADCAST_ADDR, pkt, sizeof(ProbeMsg));
  }

  event message_t * Receive.receive(message_t *msg, void *payload, 
 uint8_t len){
  if(len==sizeof(ProbeMsg)){
  probe = (ProbeMsg*)payload;
  call Timer.startOneShot(DELAY_BETWEEN_PROBES);
  }
  return msg;
  }

  event void Timer.fired(){
  SendProbe();
  }

Re: [Tinyos-help] Broadcast packet not received by all motes

2010-10-29 Thread Simon Eberz

This should not be the case, as packets are only sent as a respone and 
after a short waiting period (20ms).
Thus, the two motes can never send at the same time.

 Unless you have some randomisation before you transmit packets, sounds like
 your packets are interfering with each other. SendDone can be signaled even
 if packet's lost in propagation (I think..).

[Tinyos-help] Broadcast packet not received by all motes

2010-10-29 Thread Simon Eberz

According to the TinyOS wiki the CC2420 radio stack, which is used by 
the MICAz motes, performs a CCA by default, this should not be the problem.
Furthermore, not a single one out of the ~300 packets was received by 
the third mote, but all were received by the second one. I don't think 
the problem is interference or something similiar.

[Tinyos-help] RssiDemo Mica2 RSSI to dBm

2010-10-29 Thread Correo de Wacka



HI all,

I'm using RssiDemo to measure the rssi, and I'd like to convert the value of 
the RSSI to dBm. I've used this conversion in the java program:


rssi= msg.get_rssi();
Vrssi = (3*rssi/1024);
   
RSSI = -50*Vrssi-45.5 ;


System.out.print( Power: + RSSI + dBm );


 But the maximum value that appears is -48 dBm, even if the two Mica2 are 
together, and the transmision power is 5dBm. I've displayed the 
msg.get_rssi() as well and the values are between [20 -313]. I think that the 
range is [1-400]. 

Any idea to convert these values to dBm?


Or, -45.5 is the maximum value to measure?


Thanks for your time.

David

[Tinyos-help] using TinyOS-2.x java sdk in Matlab

hello,
I was wondering whether anyone has managed to use the TinyOS-2.x java sdk 
within Matlab? My main motivation is to stream sensor data (magnetic,angular 
rate  gravity) collected from wireless motes into matlab for real-time 
analysis (currently working with sample rates between 20Hz-50Hz). So far I have 
been following the TinyOS-1.x documentation, but have found some difficulty in 
getting things working.

Re: [Tinyos-help] Broadcast packet not received by all motes

2010-10-29 Thread Urs Hunkeler

Just an idea: maybe the third mote has some low-power radio 
implementation (low-power listening, LPL) enabled and the sending motes 
somehow do not take this into account (i.e., they do not send a 
long-enough preamble).

Cheers,
Urs

 I think it is not cased by the channel capacity, but because in Send.send()
 the

 if it do not deal with the EBUSY and FAIL state in the else condition, it
 will remain NULL. So the
 next when call Send.send() it return EBUSY, because the clientPtrs[client]
 only be reseted
 in the void packetComplete() function  which be called in the event void

    }
     
 }
 because the command SubSend.send() return not SUCCESS, so the  event
 SubSend.sendDone() will not signal, so the clientPtrs[client] remain NULL.

The return value is either FAIL or EBUSY in that else block.
If it is FAIL, we should wait until the condition that resulted in
FAIL is repaired. If it is EBUSY, that means we should wait
until sendDone.

I think we are handing the EBUSY case properly.

There is a possibility that we are not handing all the possible cases
that can result in FAIL.

I understand posting sendTask solved your problem but I want to
understand why it works and if there is any FAIL condition that we do
not handle properly before committing the fix. Do you know what return
value you were getting when this bug is triggered? If it is FAIL, what
caused that FAIL return value?
