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;
}
}
