Hi all,
I want to set the transmission power of CC2420 to maximum in MicaZ nodes.
When I call CC2420Control.SetRFPower(TXPOWER_MAX), it fails (result_t !=
SUCCESS) and sets the power to 15 (I got this value from
CC2420Control.GetRFPower(). Does anyone knows why? I think it's supposed to
be set to
day. Can this causes electric discharge on the mote and therefore the
failure of the receiver module of the mote?
Thanks,
Mohammad

Thanks again, actually I have a software background and I'm not very good
in this soldering thing, especially with this small board and limited tools
we have in our lab. I'll try these ways and I'll tell you what happens.

Thanks Paul, you're right, most likely the problem is with the antenna. But
the point is that as you know for Micaz, the antenna is a 2.4 ghz pcb
antenna! how can I re-solder it? by now I've cut the antenna of one of the
motes totally and re-soldered
is highly appreciated.
Thanks,

the range I've seen micaz/mica2 nodes work w/out an antenna
connected at all, so the antenna is likely the cause of this problem.
Hopefully re-soldering the connections fixes this and you don't have to buy
new boards,

In the application I'm working on, I need to know the exact time of a

the mote to put the time value in the packet as well (using Time.getLow32()
and Time.getHigh32, Time is SimpleTime.Time interface), using this

Hello again guys,
No reply for this problem? even any thoughts or clues? maybe I wrote it

by xserve or moteview. does anyone have any clue about the problem? I
thought the programmer (MIB510) or Serial-to-USB cable might has problem,
but if they have proble, so why I can program any motes correctly?
thanks a lot

Hi all,
I have a program that senses some data and sends them to a base station. I
installed the base station program on a mote which is attached to the MIB510
and via that is connected to a computer. But I don't know how can I see the
data that my base station receives.
I tried MoteView and
softwares like XSniffer!
Thank you very much

Hi all,
In my program I use send command (in MhopSend component) three or more
times. When the sendDone event is fired, I want to know that this sendDone
is for which send command. How can I figure out this? In other words, how
can I access the sent data in sendDone command? I tried to use data

I forgot to say that I use Micaz and TinyOS 1.1

Hi everybody,
I wanted to create a regular network of micaz sensors that each node should
create a packet and send it to the base. Well, it seems very simple, while
each node is in base's transmission range and can send the packet directly
to the base every thing is okey. But when the distance
