Hello everyone,
When sending a message, I want to know who sent it. I know that for this I
have to use the interface AMPacket.source (packet). The problem is that I
get always the same value as if it received all messages from the same node,
which is not true.
So I see how this field is set, and find that is filled in
ActiveMessageLayerC the method:
command error_t AMSend.send[am_id_t id](am_addr_t addr, message_t* msg,
uint8_t len)
{
error_t error;
error = call Config.checkPacket(msg);
if( error != SUCCESS )
return error;
call AMPacket.setSource(msg, call AMPacket.address());
call AMPacket.setGroup(msg, call AMPacket.localGroup());
call AMPacket.setType(msg, id);
call AMPacket.setDestination(msg, addr);
return call SubSend.send(msg, len);
}
So it is filled in line AMPacket.setSource call (msg, call AMPacket.address
()). I was reading the documentation of the method AMPacket.address () and
says: "Return the node's active message address associated with this AM
stack".
My question is: where does this address associated with the AM stack is
obtained? why is it always the same for different TOS_NODE_ID? (I am using a
RF230 radio).
Thanks in advance,

Ricardo
