[Tinyos-help] Question about TinyAlloc
Hello all, Now I am trying MemAlloc interface in TinyAlloc. Iam not surewhat is the maximum size of dynamically allocatable memory which TinyAllocprovides. When I tried "call MemAlloc.allocate(h, 254)", the final statusof the allocation in allocComplete event was success. But for the values more than 254, allocation was failed. So I thinkthe maximum possible size is about 256 bytes, but I am not sure. And if I want to use morememory for dynamic memory allocation, how can I do that? Can I increase the memory size for dynamic memory allocation by modifying the value of some variable in TinyAlloc? If anybody have some information about it, please let me know.

RE: [Tinyos-help] Serial Forwarder and Listen
The short answer is no, there's no CR/LF. However, the packets do come with a frame, and the frame has an escape rule that can result in escape characters being inserted. That's probably why you unexpectedly get changing packet lengths. The right way to pick packets out of the stream is to look for the framing bytes, 0x7E, which come at the beginning and the end of the packet. For details, see the often-referenced http://www.octavetech.com/pubs/TB5-01%20Deciphering%20TinyOS%20Serial%20Pack ets.pdf Regards, Ben Buckner -Original Message- Date: Wed, 18 Oct 2006 14:47:59 -0600 From: Ian Welch [EMAIL PROTECTED] Subject: [Tinyos-help] Serial Forwarder and Listen To: tinyos-help@millennium.berkeley.edu Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=iso-8859-1 When serial forwarder forwards the packets to a designated are the each terminate by a Carage Return Line Feed?

[Tinyos-help] TinyDB parser problem
Hi all,
I am trying to interact with TinyDB using matlab and I cannot seem to get
the parser to work. I believe that I import all of the appropriate java
packages and then try to execute this:
--
SQLstr=('SELECT light');
w=uint8(1);//uint is the equivalent of byte in
matlab
myQuery = net.tinyos.tinydb.parser.SensorQueryer.translateQuery(SQLstr,w);
---
and I recieve the following error:
---
Java exception occurred:
net.tinyos.tinydb.parser.ParseException
at
net.tinyos.tinydb.parser.SensorQueryer.translateQuery(SensorQueryer.java:89)
---
I believe that I need to do something along the lines of
TinyDBMain.debug=true, but I can't for the life of me figure out how to do
that in matlab.
If anyone can offer any help at all I would really appreciate it, I am at a
complete loss and have been so for weeks!
cheers,
Robert

RE: [Tinyos-help] Changing Micaz Frequency at runtime in TinyOS 2.x
I have encountered the same problem, and conducting some tests, I was able to determine that the next call to AMSend.send() after syncDone() is signaled fails to signal a sendDone() event even though the call returned SUCCESS. The node continued to be operational, and a call to CC2420Config.getChannel() returned the expected (new) channel number. However, the node was unable to receive messages on either the original channel or the new channel. Paul C. -Original Message- Can you define does not work? Does the node continue to operate at the same frequency? Does it stop being able to receive or transmit? Does it crash? Does it take a long time to change?
