[Tinyos-help] Unable to send or receive queries in spite of successfully compiling and programming mica2 motes with TinyDBApp

[shankar satish]

Hi All,

I am unable to send queries or receive any readings from TinyDB. We are
using an MIB510 and mica2 motes. The TinyDBApp compiled fine, and was loaded
successfully on three motes. Mote with ID=0 is attached to the programming
board.

I selected the attributes (NodeID, Light, Parent and Depth) and clicked on
"Send Query" and "Display topology". The Query0 window and Sensor Network
Topology window are blank. On the programming board; (Which has attached to
it a mote with ID = 0 ), initially, the yellow and red LEDs were blinking.
After some time, green LED stayed on, and red started blinking. No LED is
blinking on motes with IDs=1,2, etc.

---------------------------------I have copy-pasted TinyDB.conf file. (As
you can see, it all seems to be in
order:)--------------------------------------

% As of 8/4/03, tinydb uses the new phoenixcomm interface for
% access to the mote network.  The string below specifies what
% source you would like to talk to.  Some examples:
%  A mote on the local serial port:  serial at COM1$57600
%  A mote via the eprb: network at c62b272$10002
%  An (external) serial forwarder: sf at localhost$9000
%  Note that "$" is used in place of ":" in the configuration string
%  Also, if using old-serial or old-network, you must specify the packet
size (which is currently 56)

comm-string:serial at COM1$57600

% default query to show in text pnale
default-query:create buffer sam size 5 as (select nodeid,light)

%default catalog file

Any pointers and help is much appreciated. Thank you.
