Software Serial blocking Wifi Connection

Question

I'm trying to connect my NodeMCU to wifi. It isn't finishing because software serial is interrupting it.

Sort of like Software serial conflict with WiFi on ESP8266.

Here's my code:

#include <SoftwareSerial.h>
#include "ESP8266WiFi.h"
const char* ssid = "mywifi";
const char* password = "password123";
void setup() {
 Serial.begin(9600);
 Serial.println("");
 connectWifi();
 SoftwareSerial pinSerial(1, 3);
 pinSerial.begin(9600);
}
void loop() {
 // send data received from serial port
}
// in separate function so I can reconnect in the loop 
bool connectWifi() {
 WiFi.begin(ssid, password);
 while (WiFi.status() != WL_CONNECTED) {
 delay(500);
 Serial.print(".");
 }
 Serial.println("");
 Serial.println("WiFi connected");
 Serial.println(WiFi.localIP());
 if( WiFi.status() == WL_CONNECTED) {
 return true;
 } else {
 Serial.println("wifi connection failed");
 }
}

The console outputs the periods as it's connecting but never prints the IP and instead prints the serial data it received while trying to connect.

Can I delay the activation of the software serial port? Should I use another serial library?

Please don't focus on basic code errors, I'm still learning.

• Juraj: you start SoftwareSerial on pins of the hardware serial.
• thunder: oh you're right! how do I read and write to the hardware pins, not the usb port?
• Juraj: the USB chip of NodeMcu is wired to pins io 1 and io 3 of the esp8266 and you write and read it over Serial
• Mikael Patel: SoftwareSerial pinSerial(1, 3); in setup() is strange as it 1) uses the hardware serial pins, 2) is never used other than begin(), and 3) is destructed when returning. What are you trying to do exactly?
