we have tmotes without internal antenna and provision for external i.e
SMA connector .i have connected linksys 7dBi antennas
but it is not covering even a distance of 20 mts
what might be the problem???
please help me in this regard
i have tired the power settings using commands at the cygwin
I want to get three value from tmote sky.I use 3-axis accelerator sensor, and I
need the X, Y, Z Output.I'm unable to get three values at one time, so i try
to get one value at one time, then get three times to be a cycle.(If anyone
get some solutione like get three values at one time,
Hy guy. I have some problems with stack radio. in my project I send a
message on UART and a message on Radio. when i transmit a message on
UART, i receive once signal of sendDone and in my project i write in
this way:
call DataMsg.send(TOS_UART_ADDR,sizeof(beaconMsg), msg);
but when i
Hello
I have tried these kind of antennas and it also did not work
in an indoor scenario with 2 walls.
For 200mts in your scenario perhaps you should use TMoteMiniPro or other
nodes with a power amplifier.

Hi all,
I'm after the Location plugin offered by TinyViz. Apparently, TinyViz
is no longer supported by TinyOS 2.x. I was wondering if there's sth
equivalent in TinyOS 2.x that would provide me with the same
functionality? Thanks much,
Rui

I think what you need to do is have separate names for each ADC 'channel'
and call their getData()'s in sequence, something like this:
in the Config file:
ProjectOtherM.ADCx - ADCC.ADC[TOS_ADC_SENSORX_PORT];
ProjectOtherM.ADCy - ADCC.ADC[TOS_ADC_SENSORY_PORT];
ProjectOtherM.ADCz -
hmm, you _should_ only get one done per message send,
meaning one from the UART and one from the radio.
Using GenericComm, you need to sequence the sends such
that only one is active at a time. What I have done is
fire off the serial send from the done of the radio send.
If that doesn't work for
Are we sure that the antennas are for the right wavelength?
By linksys I guess you mean a dongle from an 802.11b,g
router? Do they have the same connector as your Tmote?
And are the connectors seated well?
Also, you're sure you disabled the internal antenna?
I think there's a capacitor that
You guys are moving the C73 capacitor over to connect the external antenna,
right?

Hi all
I want to use a dynamic array in my sensor application. Is there a way to
iniailize the array before using it like the keyword new in C++?
I defined the array as : uint16_t *dataArr
when I access it as : dataArr[numData++] = value
it gives a runtime error.
I am working with mica2 and
Dear all:
I uploaded a nesC program to a mica2(433Mhz) and the program TOSBase(433Mhz) to
the other mica2 pluged on the MIB510.
At first, everything works well. But I changed both of the mica2 motes to
another type mica2(900Mhz) and it seems that one mica2 can still send the data,
but the
You have made a pointer, but it doesn't point to anything...
or more preciesely it is probably initialized to 0, so it
points to the bottom of memory. Since there isn't any mem
management (to speak of) the easiest thing is to create
your array directly:
uint16_t dataArr[SOMEsmallSIZE];
Make sure you have selected the same frequency defines for
both devices in the relevant makefiles. E.g., I have:
PFLAGS += -DCC1K_DEF_FREQ=91670
CFLAGS += -DRADIO_XMIT_POWER=0xFF
Note that the 'regular' apps/Makelocal doesn't set any power
level for mica2's, so that might be a
The problem that I am facing is that I don't what is the value of
SomeSmallSize...
I can go the other way around by specifying a large value but I am afraid
that I may overflow the memory so is there a way to compute the available
memory?

I think this is what I was hitting against in one module I made for
using MSP430Adc12Multichannel. I thought it would be convenient to have

What were you trying to do exactly?
#define ARRAY_SIZE 50
uint8_t ar0[ARRAY_SIZE];
uint8_t ar1[ARRAY_SIZE*2];
Should work just fine.

Well actually we don't do anything to *prevent* you from calling
malloc, assuming the libc for your platform includes
