TTGO ESP32 + GSM 800l - Read SMS - TinyGSM - sms

Question

on my code i can send an sms to my target number but i don't know how to read or receive sms from target number
the tinyGSM library doesn't have the read member function and i don't know how to use AT commands
void setup() {
// Set console baud rate
SerialMon.begin(115200);
// Keep power when running from battery
Wire.begin(I2C_SDA, I2C_SCL);
bool isOk = setPowerBoostKeepOn(1);
SerialMon.println(String("IP5306 KeepOn ") + (isOk ? "OK" : "FAIL"));
// Set modem reset, enable, power pins
pinMode(MODEM_PWKEY, OUTPUT);
pinMode(MODEM_RST, OUTPUT);
pinMode(MODEM_POWER_ON, OUTPUT);
digitalWrite(MODEM_PWKEY, LOW);
digitalWrite(MODEM_RST, HIGH);
digitalWrite(MODEM_POWER_ON, HIGH);
// Set GSM module baud rate and UART pins
SerialAT.begin(115200, SERIAL_8N1, MODEM_RX, MODEM_TX);
delay(3000);
// Restart SIM800 module, it takes quite some time
// To skip it, call init() instead of restart()
SerialMon.println("Initializing modem...");
modem.restart();
// use modem.init() if you don't need the complete restart
// Unlock your SIM card with a PIN if needed
if (strlen(simPIN) && modem.getSimStatus() != 3 ) {
modem.simUnlock(simPIN);
}
// To send an SMS, call modem.sendSMS(SMS_TARGET, smsMessage)
String smsMessage = "Hello from ESP32!";
/*if(modem.sendSMS(SMS_TARGET, smsMessage))
{
SerialMon.println(smsMessage);
}
else{
SerialMon.println("SMS failed to send");
}*/
SerialAT.println("AT"); //Once the handshake test is successful, it will back to OK
SerialAT.println("AT+CMGF=1"); // Configuring TEXT mode
SerialAT.println("AT+CNMI=1,2,0,0,0"); // Decides how newly arrived SMS messages should be handled
}
void loop()
{
//readSMS(1);
//delay(1);
}
