OK. I trying to make multhops. I have three arduinos UNO.
I calling them ard_5 (id = 2), ard_8 (id = 1) and ard_3 (id = 3).
So, if you look on my first post you'll se that I put my beacon.ccp code.
Now everything on every code that had "int " or "short" I changed for "byte".

Good news!!! I am getting 2#1#0 at my first hop from ard_5 arduino to ard_8!!!
Like this ard_8 (2#1#0) -> ard_5(2#1#0) -> ard_5(3#1#0)-> ard_x(3#1#0), that is:

ard_8 just send, ard_5 receives from ard_8 and send for ard_x changing the destination, but keeping the source.

Howerver, with ard_x, I am getting like this ( 13448#88787#7878)

ard_8

Code:

#include <Service.h>
#include <Beacon.h>

//Arduino 08 -> ard_8 -> Somente envia!!!

Beacon beacon;
Service service;

// Identidade dos Arduinos
byte ard_8 = 1; //Arduino 08
byte ard_5 = 2; //Arduino 05
byte ard_x = 3; //arduino X


void setup() {     
  // comunicação XBEE a taxa de 9600 bps
   Serial.begin(9600); 
}


void loop() {
         
           
           beacon = Beacon(ard_5, ard_8, 0);
           service.enviaBeacon(beacon);
           delay(2000);
               
}

ard_5

Code:

#include <Beacon.h>
#include <Service.h>

Beacon beacon;
Beacon recebe;
Service service;

byte ard_8 = 1; //Arduino 08
byte ard_5 = 2; //Arduino 05
byte ard_x = 3; //arduino X


void setup() {     
   Serial.begin(9600); 
}


void loop() {
 
             recebe = service.recebeBeacon(ard_5);
           
             if (recebe.getDhost() == ard_5){
             delay(2000);
             //byte i = recebe.getSALTO()+1;
             beacon = Beacon(recebe.getDhost(), recebe.getShost(), recebe.getSALTO());         
             service.converteBeaconParaArrayChar(beacon);
               
              if (recebe.getDhost() == ard_5){
                  Serial.println("Ponto N");
                  beacon = Beacon(ard_x, ard_8,recebe.getSALTO() );
                  service.enviaBeacon(beacon);                 
              } 
    }     
}

ard_x

Code:

#include <Service.h>
#include <Beacon.h>

Service service;
Beacon beacon;
Beacon recebe;

byte ard_8 = 1; //Arduino 08
byte ard_5 = 2; //Arduino 05
byte ard_x = 3; //arduino X

//int led = 13;

void setup() {     
   Serial.begin(9600); 
 //  pinMode(led, OUTPUT);
}

void loop() {
 
         
              recebe = service.recebeBeacon(ard_x);
           
              if (recebe.getDhost() == ard_x){
              delay(2000);
         
              beacon = Beacon(recebe.getDhost(), recebe.getShost(), recebe.getSALTO());         
              service.converteBeaconParaArrayChar(beacon);
          }

One more thing, I changed my while from method converteArrayCharParaBeacon to:

Code:

byte  i=0;
byte vet[3];
Beacon beacon;


for (i=0; i <= 2; i++){
    vet[i] = msg[2 * i] - '0';
    i++;
}

Do you see any mistake?

OK guys, I followed your advice and now I'm using C string. However, I am getting some problen, at least less than the others!
I put some debugs in tge code to identify where are them. So, I identified that the problem is between the points
"Ponto 3------------" and "Ponto 3.1------------", that is, on the method

Code:

void Service::converteBeaconParaArrayChar(Beacon beacon)

I won't put my Beacon.cpp e .h again. I just have to say that I changed all my "short's" to "byte's"

Here is my Service.cpp

Code:

#include "Service.h"
#include "Beacon.h"
#include <stdio.h>

byte meu_id; //identificação do no raiz

//Estrutura do pacote de controle
Service::Service() {
}

Service::~Service() {/*nothing to destruct*/
}

void Service::enviaBeacon(Beacon beacon) {
if(beacon.getDhost() != 0){
  converteBeaconParaArrayChar(beacon);
}

}

Beacon Service::recebeBeacon(short id) {

Beacon beacon;
int i = 0;
char msg[20];

while(Serial.available() > 0) {
byte temp = Serial.read();
if (temp != 255){
msg[i] = (char) temp;
i = i + 1;
}
}
Serial.println("Ponto_1 -----------------");
Serial.println(msg);
/* Aqui to recebendo 2#1#0 redondinho*/

msg[i] = '\0';
if (i > 0) {
  beacon = converteArrayCharParaBeacon(msg);

Serial.println("Ponto_2-----------------");
  Serial.println(msg);
 
  delay(1000);
  Serial.flush();

if (verificaMensagemBeacon(beacon,id)) {
return beacon;
}
}
}
void Service::converteBeaconParaArrayChar(Beacon beacon) {
Serial.println("Ponto_3-----------------");

Serial.print(beacon.getDhost());
Serial.print("#");
Serial.print(beacon.getShost());
Serial.print("#");
Serial.println(beacon.getSALTO());

/* Aqui to recebendo 2#1#0 e num aleat.*/
Serial.println("Ponto_3.1-----------------");
}


Beacon Service::converteArrayCharParaBeacon(char msg[]) {
int c =0;
int  i=0;
short vet[3];
Beacon beacon;

while (msg[i] != '\0') {
if (msg[i] != '#') {
vet[c] = vet[c] * 10 + (msg[i] - '0');
}
else {
c = c + 1;
}
i = i + 1;
}
Serial.println("Ponto_4-----------------");
Serial.println(msg);

beacon.setDhost(vet[0]);
beacon.setShost(vet[1]);
beacon.setSALTO(vet[2]);

return beacon;
}

bool Service::verificaMensagemBeacon(Beacon beacon, short id) {

      //Verifica se a mensagem é para ele.
if (beacon.getDhost() == id) {
  return true;
}

return false;
}

I dont have any ideia why in the "void Service::converteBeaconParaArrayChar(Beacon beacon)" is doing what I attached in the picture?

Does anyone knows?

thanks

Hey buddy!! Calm down, I'm not ignoring your suggestion. You can note that I am having difficult to solve it!! Could you be a little bit humble and pacient??? I am new here, ok?
I'm being humble, I am always being grateful four your help!!! So, calm down!! If you do not want to help, ok? I think it would have more people wanting to help.
However, I am grateful for your attention to solve my problem.

Hi guys, I've been really diligent to solve this problem and I have to appreciate your help. A good news is that 50% of the problem was solved. In the code I changed what you suggested below on methods "converteBeaconParaString", "enviaBeacon" and "converteStringParaBeacon". Look that in the last now I looking for the "#" ah hand an

Code:

#include "Service.h"

#include "Beacon.h"
#include <stdio.h>
#include <string.h>


short meu_id; //identificação do no raiz

//Estrutura do pacote de controle
Service::Service() {
}

Service::~Service() {/*nothing to destruct*/
}

void Service::enviaBeacon(Beacon beacon) {
if(beacon.getDhost() != 0){
  converteBeaconParaString(beacon);
}
}

Beacon Service::recebeBeacon(short id) {

Beacon beacon;
String msg;

while(Serial.available() > 0) {
byte temp = Serial.read();
if (temp != 255){
msg = msg + (char) temp;
}

}
if (msg.length() > 0) {
  beacon = converteStringParaBeacon(msg);
  delay(1000);
  Serial.flush();

if (verificaMensagemBeacon(beacon,id)) {
return beacon;
}
}
return beacon;
}


void Service::converteBeaconParaString(Beacon beacon){

Serial.print(beacon.getDhost());
Serial.print("#");
Serial.print(beacon.getShost());
Serial.print("#");
Serial.println(beacon.getSALTO());
}


Beacon Service::converteStringParaBeacon(String msg) {
int c=0;
int i=0;
short vet[3];
Beacon beacon;

while (msg[i] == '\0') {
if (msg[i] != '#') {
vet[c] = vet[c] * 10 + (msg[i] - '0');
}
else {
c = c + 1;
}
i = i + 1;
}

beacon.setDhost(vet[0]);
beacon.setShost(vet[1]);
beacon.setSALTO(vet[2]);

return beacon;
}


bool Service::verificaMensagemBeacon(Beacon beacon, short id) {

if (beacon.getDhost() == id) {
  return true;
}

return false;
}

Now, when I send the information from ard_8 -> ard_5, I get what I wanted (2#1#0+1). 50% of the problem solved!!!!
HOWEVER, when I get this information (2#1#0+1) and change de destination for ard_x, the thrird arduino, I get like this (76656#56663#88877)
Really, annoying!!!

Any suggestion?

Thanks a lot folks.

Ok guys, I'll work on it!!!
I would search for C String and choose one wich fits better.

thanks a lot

And the reason to not use it.
Can you explain me and give me a tip about how to use what do you think is better in my code?

And use what?? You didnt tell me the suggestion!!!
Array of bytes, char... ???

Ok, here is my whole code:
What suggestion you give me with String class??
thanks

Ok Ok, I agree with your comment!!!
I really need that when the arduino get the packet, it doen not come with so much garbage. I think the problem is with the "recebe" method.
But I really do not know what is happening. One told me to handle XCTU for xbee, I'm looking for information about this.
What do you think??

thanks

Hey, about the 255 code I've  put this, but it doesnt function!!!

Code:

Beacon beacon;
String msg;

while(Serial.available() > 0) {
byte temp = Serial.read();
if (temp != 255){
msg = msg + (char) temp;
}

}

Do you have more suggestion?

Thanks folks,

Code:

Beacon Service::converteStringParaBeacon(String msg) {
int c, i;
short vet[3];
Beacon beacon;
for (c = i = 0; c < 3; c++) {         [b]  // If I put c<3 and not c<2 it get worst [/b]
vet[c] = (short) msg.substring(i, msg.indexOf('#', i)).toInt();
i = msg.indexOf("#", i) + 1;
}

beacon.setDhost(vet[0]);
beacon.setShost(vet[1]);
beacon.setSALTO(vet[2]);

return beacon;
}

Look at the picture!!! At leat with C<2 I still get in the midle of garbage 2#1#0# ahuahuahah

But, I thank you so much for help. Please, stay with me!

Olá amigão,

Então não é problema de bauds, já usei a 19200 e 9600 e a 19.200 acontece a mesma coisa.
Nunca mexi nessa parte de configuração. Vou tentar ler estes tutoriais que você me passou? Não lembra mesmo o que você fez?? :/

muito obrigado.

@ Sergio

I appreciate your attention. The bug is already corrected I've put

Code:

short vet [3];

@smarcelo
Thanks too. I didnt understand, but can you help me solve it? Do you know how to solve it?
I'd appreciate.

Olá amigo, obrigado pela atenção.

Então, o que eu estou fazendo é usar tres cabos seriais, do tipo de cabo de impressora, um em cada arduino.
Os tres arduinos tem um skield Xbee, mas eles estao conectados no computador. Faço a comunicação assim, para depois poder usar eles com pilha!!
Não configurei Xbee, você teve problema parecido? Pode me explicar como fez?

abs e muito obrigado.

1) char array´s.
How can I do it, please? Can you give a tip?

I think if you see the whole code it´ll get clear;
This is my Beacon.cpp

Code:

#include "Beacon.h"
#include <stdio.h>
#include <string.h>

Beacon::Beacon() {
}

Beacon::Beacon(short meu_id) {
this->dhost = 0; // host de destino
this->shost = 0; // host de origem
this->salto = 0; // (metrica SALTO, numero de saltos para cada no)
//this->meu_id = meu_id;
}

Beacon::Beacon(short dhost, short shost, short salto) {
this->dhost = dhost; // destination host
this->shost = shost; // source host
this->salto = salto; // hops

}

This is my Service.cpp

Code:

//send beacon
void Service::enviaBeacon(Beacon beacon) {
if(beacon.getDhost() != 0){
  String msg = converteBeaconParaString(beacon);
  Serial.println(msg);
}

}
//receive beacon
Beacon Service::recebeBeacon(short id) {

Beacon beacon;
String msg;

while(Serial.available() > 0) {
byte temp = Serial.read();
msg = msg + (char) temp;

}
Serial.flush();


if (msg.length() > 0) {
beacon = converteStringParaBeacon(msg);
delay(1000);
Serial.flush();


if (verificaMensagemBeacon(beacon,id)) {
return beacon;
}
}
return beacon;
}
//convert Beacon to String
String Service::converteBeaconParaString(Beacon beacon) {
char buf[10];
sprintf(buf, "%d#%d#%d#", beacon.getDhost(), beacon.getShost(), beacon.getSALTO());
return buf;
}

//convert  String to Beacon
Beacon Service::converteStringParaBeacon(String msg) {
int c, i;
short vet[2];
Beacon beacon;
for (c = i = 0; c < 2; c++) {
vet[c] = (short) msg.substring(i, msg.indexOf('#', i)).toInt();
i = msg.indexOf("#", i) + 1;
}

beacon.setDhost(vet[0]);
beacon.setShost(vet[1]);
beacon.setSALTO(vet[2]);

return beacon;
}

Clear now? Any suggestion?

Thank a lot.
