I have been trying to read the received sms from GPS/GPRS/GSM Module V3.0 via the serial port to a variable for manipulation purposes and all I receive is as below
This way you can tell the SIM800L module either to forward newly arrived SMS messages directly to the PC, or to save them in message storage and then notify the PC about their locations in message storage. Its response starts with +CMT: All the fields in the response are comma-separated with first field being phone number. The second field is. /. This code works with SIM800L Evb version, it sets the module on receiving SMS mode. And when the user sends SMS it will be shown on the serial monitor. The receiving mode is only set at the setup, you can later set the mode you want and check the AT functions you want. It's a basic code to test the SIM800L. Refer to www.SurtrTech.com for more detaims./ #include. I have a Huawei Modem connected to my VB.net project all AT Commands work such as CONNECT, READ and SEND SMS The only thing that I cannot work with is the DELETE SMS I have this code: With Seria.
AT
AT+CMGF=1
AT+CPMS='SM'
AT+CMGL = 'ALL'
63
AT
OK
AT+CMGF=1
OK
AT+CPMS='SM'
+CPMS: 2,25,2,25,2,2
The sim has two SMSes that can be viewed when you run the commands via USD
The code is
byte gsmDriverPin[3] ={3,4,5};
int numdata;
boolean started=false;
char smsbuffer[160];
char n[20];
String inData;
void setup() {
//pinMode(13, OUTPUT);
digitalWrite(5,HIGH);//Output GSM Timing
delay(1500);
digitalWrite(5,LOW);
digitalWrite(3,LOW);//Enable the GSM mode
digitalWrite(4,HIGH);//Disable the GPS mode
delay(2000);
mySerial.begin(9600); // the GPRS baud rate
mySerial.print('r');
delay(1000);
Serial.begin(9600); //set the baud rate
delay(5000);//call ready
delay(5000);
delay(5000);
//Init the driver pins for GSM function
for(int i = 0 ; i < 3; i++)
{
pinMode(gsmDriverPin[i],OUTPUT);
}
}
void loop()
{
Serial.println('AT'); //AT is sent to the GSM / GPRS modem to test the connection
delay(2000);
//Serial.println('AT');
// p_char=Serial.read();
//Serial.write(p_char);
// delay(2000);
Serial.println('AT+CMGF=1'); //instruct the GSM/GPRS modem or mobile phone to operate in SMS text mode.
delay(2000);
// p_char=Serial.read();
//Serial.write(p_char);
delay(2000);
Serial.println('AT+CPMS='SM'); // instruct the GSM/GPRS modem or mobile phone to use the message storage area in the SIM card
delay(2000);
//Serial.write(Serial.read());
//delay(2000);
Serial.println('AT+CMGL = 'ALL'); //retrieve all SMS messages received
delay(2000);

Serial.println(h);
