[solved] Read AT Command

Using Arduino Networking, Protocols, and Devices
1

Hi,

My doubt is how to take an AT responde and put it into a variable.
I send a AT command to syncronise the Arduino with a NTP server.
Then I ask the hour with AT+CCLK?, and I receive a responde like:

+CCLK: "17/02/21,10:57:47+04"

I want to take the date : ""17/02/21,10:57:47+04"" and put into a char or string.

How can i do it?

I'm using an GPRS shield based on a SIM900.

Use Serial.available() and Serial.read(), if your device is connected to the Serial pins.

PaulS:
Use Serial.available() and Serial.read(), if your device is connected to the Serial pins.

I do that: String aux;
SIM900.println("AT+CCLK?");
delay(1000);
if(SIM900.available()){
while(SIM900.available()>0){
aux.concat(SIM900.read());
}

And the answer i get its:
131065844367677675631310131043676776755832344955474850475050444857585155585256434852341310131079751310

I think it could be ASCII? I only have to parse to char?

Yes, only i had to parse and i have the AT response, thanks!!

How did you parse that data?

No parsing should have been necessary.

   while(SIM900.available()>0)
   {
      char ltr = SIM900.read();
      aux.concat(ltr);
   }
