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

• James Waldby - jwpat7: You may need to say how you receive the message or how it's stored. As is, the question is vague. Also edit the question and add an explained example, like "{14:C:123}"

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);
