How to split a string received via a GSM module (message)

Question

I am doing a motorcycle security system. In this system, I will receive a message from GSM in the form {password:operation (like start,stop,alarm):time}. Example:(9990:start:30)

now i need to split each term seperately (a=9990,b=start,c=30).help me to solve

Answer 1

Simplest solution is to use sscanf().

  int password;
  char operation;
  int time;
  char* buf = "{14:C:123}";
  int n = sscanf(buf, "{%d:%c:%d}", &password, &operation, &time);
  Serial.print(F("n="));
  Serial.println(n);
  Serial.print(F("password="));
  Serial.println(password);
  Serial.print(F("operation="));
  Serial.println(operation);
  Serial.print(F("time="));
  Serial.println(time);
