Error PDU encode
PostPosted: Wed Sep 07, 2016 7:23 pm     Reply with quote
Hi,

I'm using this code http://www.ccsinfo.com/forum/viewtopic.php?t=34800&highlight=pdu to encode one PDU format a string, this works in some cases and in others a couple of characters at the end is lost, for more I try I can not find the error.

Someone can help me?

Here is my code:
Code:
#include <18F4620.h>
#DEVICE ADC=8
#fuses HS,WDT32768,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)// RS232 Estándar

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

int i,r,w;
int Long_Buffer;
int Long_Data_PDU;

char buffer[]="$GPSMS,862170014677098,18,23.99,14.99,4.99,3.29,VERT,OPEN,26.25,094559,010000,*";       //ERROR!
//char buffer[]="$GPSMS,862170014677098,18,23.99,14.99,4.99,3.29,NOVERT,OPEN,26.25,094546,010000,*";    //OK
char PDU_Buffer[100];


int main(){
   Long_Buffer = strlen(buffer);
   r = 0;
   w = 0;

while (r<Long_Buffer) {
   PDU_Buffer[w]=((buffer[r]>>(w%7))&0x7F) | ((buffer[r+1]<<(7-(w%7)))&0xFF);
   if ((w%7)==6){
      r++;
    }
    r++;
    w++;
   }

while (TRUE);
}

Go to this site:
<http://www.smartposition.nl/resources/sms_pdu.html>

Put your message into the source tab.
Convert it.

How long is the output?. I count more than 100 characters....

Your target buffer needs to be at least 2*message length+1 characters.
