Lilygo TTGO T-Call V1.4 correct way to know that it is connected? #650

Open Jeronimo17 opened 2 years ago

Hi, I got everything to work fine but after the idle time when trying to send a new data it does not work.

I was using:

if (!modem.gprsConnect(apn, gprsUser, gprsPass)) {
    SerialMon.println(" fail");
    delay(10000);
    return;
  }

If I do so:

  if (!modem.isNetworkConnected()) {
    SerialMon.print(F("Esperando red..."));
    if (!modem.waitForNetwork()) {
      SerialMon.println(" fallo");
      delay(10000);
      return;
    }

    SerialMon.println(" OK");

    SerialMon.print(F("Conectando a "));
    SerialMon.print(apn);
  }
  if (!modem.gprsConnect(apn, gprsUser, gprsPass)) {
    SerialMon.println(" fail");
    delay(10000);
    return;
  }

It works but every time it sends a data it seems to reestablish the connection even though it is already established.

What is the correct way to know that you are connected? Thank you
