Electron TCPClient.connect() is always returning true?

Tags: #<Tag:0x00007f1ca0438af0>


I have a project that connects to a TCP socket server.
I have realized that TCPClient.connect() function always returns true. No matter if server exists or not. Do am I missing something? Or is it really an incorrect behaviour?

DeviceOS: v1.0.1
3rd Party Sim

#define		TCP_SERVER	"noMatterWhatIsAddedHere.alWaysReturns.true"
#define		TCP_PORT		6666

TCPClient tcp_client;
bool doOnlyOnce = false;

// Connects to a cellular network by APN only
STARTUP(cellular_credentials_set("m2m.movistar.es", "", "", NULL));

// define system mode

//enable system thread

// setup() runs once, when the device is first turned on.
void setup() {
  // Put initialization like pinMode and begin functions here.



// loop() runs over and over again, as quickly as it can execute.
void loop() {
  // The core of your code will likely live here.

  if (Particle.connected() == false)
    if (!doOnlyOnce){

      Serial.printlnf("Connecting to... %s:%d", TCP_SERVER, TCP_PORT);

      if (tcp_client.connect(TCP_SERVER, TCP_PORT))
        Serial.println("TCP socket connected!");  // <<<<<< It does not matter where it connects. Always is entered into this condition
        Serial.println("TCP socket connection error");  // <<<<<< Never entered into this condition. It does not matter if server does not exist

      doOnlyOnce = true;
