Dinesh,
you can communicate to base station (the mote connected to PC) over a
serial cable if you were using MIB510 programming board.
There is a Java class to do that, but I have never used it.
I have developped a C++ program to communicate to the base station.
Then I can receive and send messges to the WSN. I can even send commands to
specific nodes into the network.
MIB520 uses USB as a serial port, then the program will probably work
on this program board as well. You can see information about MIB510 and MIB520
in the "MPR/MIB Users Manual" from Crossbow.
You have to send a command to the base station over a message. Then You
have to send 7E flag, destination address, . . . . , CRC and final 7E flag.
If your sent message is not correct, the base station will do nothing.
You must to know the format of the raw message.
Here is the code to calculate CRC:
WORD crcByte(WORD crc, const BYTE& b)
{
BYTE i;
crc = crc ^ b << 8;
i = 8;
do
if (crc & 0x8000)
crc = crc << 1 ^ 0x1021;
else
crc = crc << 1;
while (--i);
return crc;
}
