+1 guix suggestion, '' is a special character used as escape char.

I posted a code to split an array using strtok_r, check this post Split string by delimiter or check string for a value. - #7 by sarouje - Programming Questions - Arduino Forum

If you wanted to use String then below code will be helpful

String split(String data, char separator, int index)
{
  int found = 0;
  int strIndex[] = {0, -1};
  int maxIndex = data.length()-1;

  for(int i=0; i<=maxIndex && found<=index; i++){
    if(data.charAt(i)==separator || i==maxIndex){
        found++;
        strIndex[0] = strIndex[1]+1;
        strIndex[1] = (i == maxIndex) ? i+1 : i;
    }
  }

  return found>index ? data.substring(strIndex[0], strIndex[1]) : "";
}


//How to call
String myString = "0x77|2|2|3|0x88";
String splited = split(myString, '|',0)
//returns 0x77
