Arduino --> Strange behaviour of terminal

Support Software & Applications
1

Hi,

i’ve installed a fresh linux manjaro system (21.0.7) with newest version of Arduino (from the repository).

Now the following code

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <WiFiClient.h>

// Initialisierungen
ESP8266WebServer server(80);
WiFiClient wifiClient;

const char indexPage[] PROGMEM = R"=====(
Test
)=====";



void setup() {
  Serial.begin(115200);
  WiFi.mode(WIFI_AP);
  WiFi.softAP("test", "123456789");
  Serial.print("Accesspoint address: ");
  Serial.println(WiFi.softAPIP());
  server.on("/", display_root);
  server.begin();
}

void loop() {
  server.handleClient();
  delay(500);
}

void display_root() {
  Serial.println("Display root");
  server.send(200, "text/html", indexPage);
}

gives me the following output in Arduino Serial-Monitor

in my previous manjaro system with previous Arduino version i didnt have this output.
Also i tried same code on my windows machine and i don’t get this Serial-Monitor Output there.
Has anyone an idea, why the linux version behaves different from windows version?

You are asking something we cannot possibly know.

A wild guess is the version of the default compiler on the system in question.

Your question is more suited for an Arduino forum than Manjaro.
