6 years ago That's what I tried: change RX,TX pins does not change anything. It looks like that the _ readSerial functions only returns the command and did not contain the response from the module
Perhaps just a personal issue, but I get wrong responses from setPin. When I enter the correct pin it returns false and everything works fine. But when I enter the wrong pin it also returns false (and not true as you state in the description). if ( (_readSerial(5000).indexOf("ER")) == -1) { return false; } else return true;
When I type the AT-Commands in by hand everything works fine. I hope that there is a solution. Thank you :-)
Here my code:
include
include
define RX 5
define TX 4
Sim800L GSM(RX, TX);
void setup(){ pinMode(11, OUTPUT); digitalWrite(11,HIGH); //turns on the Sim800L module
Serial.begin(9600); GSM.begin(4800);
String pin = "4311"; delay(5000);
if (GSM.setPIN(pin)) Serial.println("Pin set"); else Serial.println("Pin NOT set");
}
void loop(){
}
