hii every budy /// im trying to send 2 float numbers via xbee using packet marker () {} ... my problem that i cant find the original arduino code for this method i found several codes for proccessing and bytes but couldent make it work ... so if any one can direct me into asimple arduino code it would be great cus i realy searched alot /// thanks in advance ///

boolean started = false;
boolean ended = false;

char inData[24]; // Size as appropriate
byte index = 0;

#define SOP "{"
#define EOP "}"

void loop()
{
   while(Serial.available() > 0)
   {
      char inChar = Serial.read();
      if(inChar == SOP)
      {
         started = true;
         index = 0;
         inData[index] = '\0';
      }
      else if(inChar == EOP)
      {
         ended = true;
         break;
      }
      else
      {
         if(index < 24-1) // Array size
         {
            inData[index++] = inChar;
            inData[index] = '\0';
         }
      }
   }

   if(started && ended)
   {
      // Parse the data in inData here...
   }
}

thanks alot paul i will try this code cus mine is very very long here :

void setup()
{
Serial.begin(9600);
}
void loop()
{
char charIn = 0;
byte i = 0;
char stringIn[32] = "";

char startchar;
float availableData = Serial.available();

if ( availableData > 0 ) {
startchar = Serial.read();
if ( startchar == '{' ) {
while ( charIn != '}' ) {
if ( Serial.available() > 0 ) {
charIn = Serial.read();
if ( charIn == '}' ) {
break;
}
stringIn = charIn;

  • i += 1;*
  • }*
  • }*
  • float lat1= atof(stringIn);*
  • Serial.println(lat1,7);*
  • delay(3000);*
  • }*

if ( startchar == '(' ) {

  • while ( charIn != ')' ) {*
  • if ( Serial.available() > 0 ) {*
  • charIn = Serial.read();*
  • if ( charIn == ')' ) {*
  • break;*
  • }*
    _ stringIn = charIn;_
    * i += 1;*
    * }*
    * }*
    * float lon= atof(stringIn);*
    * Serial.println(lon,7);*
    * delay(3000);*
    * }*
    }
    }

float availableData = Serial.available();

Serial.available() can hardly report that there are 3 and half characters to read, now, can it?

  char charIn = 0;
  byte i = 0;
  char stringIn[32] = "";

With these as local variables, an entire packet would need to be available to be read in a single iteration of loop. That seems highly unlikely.
