I created the next string "Split" function for Arduino/ESP boards. The performance is OK (25ms/Split)
void setup() {
Serial.begin(115200);
delay(1000);
Serial.println("*** Start...");
String s = "1612248989;Random string with SPACES;192.168.2.2;192.168.3.3;64;16;ABCDE2345678987BCEF";
Serial.println(s);
Serial.println(Split(s,";",2));
Serial.println("*** End.");
}
void loop() {
// put your main code here, to run repeatedly:
}
String Split(String aString, String Delimiter, int Index) {
String bString ="", fragment = "";
int delimiterIndex, i = 0;
bString = aString;
do {
i++;
delimiterIndex = bString.indexOf(Delimiter);
if (i == Index) {
fragment = bString.substring(0,delimiterIndex);
}
bString = bString.substring(delimiterIndex+1);
bString.trim();
} while (delimiterIndex != -1);
return fragment;
}
Result:
18:24:44.626 -> *** Start...
18:24:44.626 -> 1612248989;Random string with SPACES;192.168.2.2;192.168.3.3;64;16;ABCDE2345678987BCEF
18:24:44.626 -> Random string with SPACES
18:24:44.626 -> *** End.
