T-SIM7600G Call + SMS

[NicoYaez]

Hello, good day. I would like to know if someone implemented calls on the 7600. What happens to me is that I would like to end the call after a few seconds so that the subsequent actions can execute correctly, such as sending a message. However, since the call is not disconnected, the message remains in a queue and gets sent some time after the call, causing a delay in the entire 'for' cycle. If anyone can help me with this, I would appreciate it. Here's the code

for (int i = 0; i < sizeof(phoneNumbers) / sizeof(phoneNumbers[0]); i++) {

DBG("Llamando:", phoneNumbers[i]);
SerialAT.println("ATD" + String(phoneNumbers[i]) + ";");
modem.waitResponse();
light_sleep(20);
SerialAT.println("ATH");
modem.waitResponse();
delay(5000);

bool success = modem.sendSMS(phoneNumbers[i], message); // send SMS
Serial.println(success ? "SMS sent successfully" : "SMS sending failed");
// Wait for the SMS to be sent
delay(10000);
}

Check the manual

AT+CVHU=0
OK
ATH
VOICE CALL: END: 000017
OK

e.g.,

for (int i = 0; i < sizeof(phoneNumbers) / sizeof(phoneNumbers[0]); i++) {
    DBG("Llamando:", phoneNumbers[i]);
    SerialAT.println("ATD" + String(phoneNumbers[i]) + ";");
    modem.waitResponse();
    light_sleep(20);

    // Hang up after 5 seconds
    delay(5000);
    SerialAT.println("ATH");
    modem.waitResponse();

    bool success = modem.sendSMS(phoneNumbers[i], message); // send SMS
    Serial.println(success ? "SMS sent successfully" : "SMS sending failed");

    // Wait for the SMS to be sent
    delay(10000);
}
