shut down modem

[rgusso]

hi, i'm using the example and i'm able to start the modem using this part:

//A7670 Reset
pinMode(RESET, OUTPUT);
digitalWrite(RESET, LOW);
delay(100);
digitalWrite(RESET, HIGH);
delay(3000);
digitalWrite(RESET, LOW);

pinMode(PWR_PIN, OUTPUT);
digitalWrite(PWR_PIN, LOW);
delay(100);
digitalWrite(PWR_PIN, HIGH);
delay(1000);
digitalWrite(PWR_PIN, LOW);

But now i want to turn it off , how do i do?

Have you looked at the AT command reference?

AT+CPOF

Or the Chinese datasheet shows a 2.5 sec pulse for Toff in section 3.2.2
