BCastInject _should_ format messages correctly and do the CRC,
but I've not used it so I can't swear to how to go about it.
As I said I suspect there is something wrong with your message
formatting, so check though the whole thing. SerialForwarder,
to my knowledge does just that, forward, so if the message is
not correct to start with it won't get better. You can see how
I went about sending and receiving messages in the Java portion
of the code I refed, which is mostly based on Listen.java.

Thank you Michael…
I appreciate your help …

Regarding the middleman.. I have peevishly cutoff the serial forwarder
and I used my own C# application but I couldn’t calculate the CRC,
therefore I faced many problems.
So I want to use serial forwarder I guess that .. I shouldn’t calculate
the CRC.
Regarding the actual message I am using to generate it the BcastInject .
Also I update the code to the below one, and tested it but nothing
worked.. exactly I removed the two lines
call SendMsg.send(TOS_UART_ADDR, sizeof(*m),m);
call Leds.greenToggle();
from it .
//sendreceive.nc
configuration sendreceive { }
implementation
{
components Main, sendreceiveM, LedsC, UARTComm as Comm;
Main.StdControl -> sendreceiveM;
sendreceiveM.Leds -> LedsC;
sendreceiveM.CommControl -> Comm;
sendreceiveM.ReceiveMsg -> Comm.ReceiveMsg[32];
sendreceiveM.SendMsg -> Comm.SendMsg[10];
}
//sendreceiveM.nc
module sendreceiveM{
provides interface StdControl;
uses {
interface Leds;
interface StdControl as CommControl;
interface SendMsg;
interface ReceiveMsg;
}
}
implementation
{
command result_t StdControl.init() {
call Leds.init();
call CommControl.init();
return SUCCESS;
}
command result_t StdControl.start() {
call CommControl.start();
return SUCCESS;
}
command result_t StdControl.stop() {
call CommControl.stop();
return SUCCESS;
}
event result_t SendMsg.sendDone(TOS_MsgPtr sent, result_t success) {
return SUCCESS;
}
event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr m) {
call Leds.redToggle();
return m;
}
}
