Re: [Tinyos-help] Variable with static TOS_NODE_ID
Hi Andre, It's difficult to tell what's going on here as this kind of problem really needs a small, concise piece of code to help explain what you are doing (see https://stackoverflow.com/help/mcve for some pointers). I'm not sure but I think you may be misunderstanding the sequence of events happening, here's some thoughts and hopefully something will help: - Your startDone function fires every time the radio is turned on, and it sends *a brand new packet* with it's nodeid value set to the that node's TOS_NODE_ID. When you say "When node 13 is to retransmit, the starDone function loads nodeid = 13 (is the Node that is transmitting), this is what is wrong, since I wanted nodei = 24 to remain unchanged" I'm really confused by this, perhaps this is what you are misunderstanding? What is happening in your startDone function is not retransmitting a received packet, it is sending a new packet. Are you trying to create a mesh network? Look at TinyOS Collection Tree Protocol (CTP) which handles packet sniffing and retransmissions for you. Trying to implement an efficient mesh network from scratch is rather complicated. - I think that the receive event is only signalled when a packet arrives which is addressed to that node. If you want to 'sniff' messages in the air destined for another node, you need to use the AM Snoop component, not Receive - The CC2420 by default does not signal any packets received which are not addressed directly to this node. So to use Snoop with CC2420 I think you need to use the CFLAGS += -DCC2420_NO_ADDRESS_RECOGNITION in your Makefile. - In your startDone event you are setting your message value to the static TOS_NODE_ID value (rcm->nodeid = TOS_NODE_ID ) but then a couple of lines later in your debug statement you are printing the nodeid variable, which is different (that seems to be set in your Receive event with nodeid= rcm->nodeid;) This seems wrong...? - When you say "But in the output of the debug, the [origin =% hu] is always equal value [trans =% hu]" isn't this what should be happening?

Re: [Tinyos-help] Variable with static TOS_NODE_ID
In your startDone function, your line:
dbg("teste", "ENVIAR_PKT_DADOS: destino %hu nodeid %hu slot %hu [cont %hu]
no tempo=%lu.\n", syncwith, nodeid, slot, cont, call Clock.get());
As far as I can tell, you haven't actually declared or assigned a variable
called 'nodeid'. Perhaps you meant to use TOS_NODE_ID instead?

Subject: [Tinyos-help] Variable with static TOS_NODE_ID
Hello friends,
I need some help.
I need to store in a variable (nodeid) the source node of a package, so that
this variable does not receive new value with each hop.
In summary, if a tree of height 3, where node 0 is the root, node 2 child of
the root and parent of node 7, need that when a packet leaves node 7, nodeid
variable receives the value of 7, pass By its parent (node 2) without being
altered and reaches the root with the same value 7. My shipping code looks
like this:
event void AMControl.startDone(error_t err) {
radio = TRUE;
dbg("teste","SLOT_ATIVO: No %hu no slot [%hu] com tempo=%lu.\n",
TOS_NODE_ID, slot, call Clock.get());
if (err == SUCCESS) {
if ((call Clock.get() > (ultpkdados+5000)) && (TOS_NODE_ID != 0)){
teste_msg_t* rcm = (teste_msg_t*)call Packet.getPayload(,
sizeof (teste_msg_t));
rcm->tipo=1;
rcm->nodeid = TOS_NODE_ID;
rcm->slot = slot;
rcm->proxsalto = syncwith;
rcm->cont = cont;
call PacketAcknowledgements.requestAck();
if (call AMSend.send(syncwith, , sizeof(teste_msg_t)) ==
SUCCESS) {
dbg("teste", "ENVIAR_PKT_DADOS: destino %hu nodeid %hu slot
%hu [cont
%hu] no tempo=%lu.\n", syncwith, nodeid, slot, cont, call Clock.get());
cont++;
ultpkdados = call Clock.get();
locked = TRUE;
}
} else ..
My reception code looks like this:
event message_t* Receive.receive(message_t* bufPtr, void* payload, uint8_t
len) {
uint16_t transmissor;
uint16_t destino;
uint16_t seqnumin;
if (len != sizeof(teste_msg_t)) {return bufPtr;}
else {
teste_msg_t* rcm = (teste_msg_t*)payload;
if (rcm->tipo == 1) {
if (TOS_NODE_ID == rcm->proxsalto){
if (TOS_NODE_ID ==0){
transmissor = call AMPacket.source(bufPtr);
cont = rcm->cont;
nodeid= rcm->nodeid;
slotin = rcm->slot;
dbg("teste", "SORVEDOURO: [trans=%hu] [origem=%hu] [slot
%hu] [cont-%hu] [time=%lu].\n", transmissor, nodeid, slotin, cont, call
Clock.get());
} else .
However in the output of the debug nodeid always is = 0:
dbg("teste", "ENVIAR_PKT_DADOS: destino %hu nodeid %hu slot %hu [cont %hu]
no tempo=%lu.\n", syncwith, nodeid, slot, cont, call Clock.get());
and
dbg("teste", "SORVEDOURO: [trans=%hu] [origem=%hu] [slot %hu] [cont-%hu]
[time=%lu].\n", transmissor, nodeid, slotin, cont, call Clock.get());
But in the output of the debug, the [origin =% hu] is always equal value
[trans =% hu]
I do not know what I'm missing
Thanks in advance for any help.
