Hello,

Use a char array instead of a String object.

The strtok() function is to be used with nullterminated strings and not with "String" objects.

char str[] = "26.90-59.30/30.90-60.30/25.40-69.30";

ok thanks :slight_smile: it worked but still a problem while displaying, this is what i got :

"26.90-59.30-60.30-69.30" into tokens:
26.90
59
30
60
30
69
30

Here's my code for spliting with strtok() :

char str[] ="26.90-59.30-60.30-69.30";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str,"-");
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    delay(1000);
    pch = strtok (NULL, " ,.-");
  }

now it looks fine :smiley: thank you all

the problem was with this line i forgot to edit it

    pch = strtok (NULL, "-");
