I have discover the great possibility to verify if a packet it is
received/delivered by the node sending using the interface PacketLink
interface : i have read the 126 TEP.
I use the component CC2420ActiveMessageC and this components provide the
interface PacketLink .I have a little problem when on the 126 TEP is said :
Developers can simply define the preprocessor variable PACKET_LINK to compile
the functionality of the PacketLink layer in with the CC2420 stack.
This means that I must set in the makefile
PFLAGS += -PACKET_LINK
and so wiring the interface PacketLink to the component CC2420ActiveMessageC
the commands that I have used
command void setRetries(message_t *msg, uint16_t maxRetries)
command void setRetryDelay(message_t *msg, uint16_t retryDelay)
are ok .For the moment I use those two command in a send function :
error_t sendData(uint8_t *buf,uint8_t adr)
{
if(!busy)
{
ppkt=(CCRadioData*)call
AMSend.getPayload(&pkt,sizeof(CCRadioData));
popolaRadioData(buf);
call PacketAcknowledgements.requestAck(&pkt);
call PacketLink.setRetries(&pkt,5);
call PacketLink.setRetryDelay(&pkt,20);
errore=call AMSend.send(adr,&pkt,sizeof(CCRadioData));
busy = TRUE;
if(errore != SUCCESS)
{
printf("errore mandaFoto %d\n",errore);
printfflush();
busy = FALSE;
}
}else
{
errore = BUSY;
}
return errore;
}
and I have no problem at compile time but I believe that the PacketLink
commands are not working correctly because with PacketAcknowledgements I see
if a packet it isn't delievered
Any suggestion is really appreciate :thank in advance.
Giorgio
