Problems with IDE 2.3.6 and ESP32 version 3.2.0

[roliwa]

Board

ESP32 Wroom using ESP32-WROOM-DA Modul Board

Device Description

I use my sketch with IDE 2.3.4 and ESp32 version 3.1.1 without Problems. I was informed about new IDE
3.2.0 and installed it as well as related Boards ....
I had some Issues with USB flash at the beginning. Even more issue 👍

d:\SynologyDrive\Development\Arduino-ESP8622\Sample Sketches\libraries\OneWire\OneWire.cpp:599:22: warning: extra tokens at end of #undef directive
599 | # undef noInterrupts() {portMUX_TYPE mux = portMUX_INITIALIZER_UNLOCKED;portENTER_CRITICAL(&mux)
| ^

600 | # undef interrupts() portEXIT_CRITICAL(&mux);}

Still Sketch compile continue and was flashed . But the WIFI connection did not work in my sketch anymore

When I flashed it with the prev version of IDE/ESP32 --- everything worked fine .. what was messed up ?

Debug Message

not needed I guess

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

Move WiFi.begin(ssid, password); before the while loop. Calling it in a loop is a bad idea

tasmota (@Jason2866) maintains a version of onewire that works with esp32.

Does not Point to error which was introduced. I do not know the root cause, but have found out, that with the new IDE setup the Sample sketched like "DS18x20_Temperature do not compile without the error described anymore !!
I did minimize it to

#include <OneWire.h>

// OneWire DS18S20, DS18B20, DS1822 Temperature Example
//
// http://www.pjrc.com/teensy/td_libs_OneWire.html
//
// The DallasTemperature library can do all this work for you!
// https://github.com/milesburton/Arduino-Temperature-Control-Library

void setup(void) {
}
void loop(void) {

}

--> same error !! By adding on the top #include <Arduino.h> it will be compiling without error

SO what has now changed -- Sample sketches wrong or IDE messed something up ?

Move WiFi.begin(ssid, password); before the while loop. Calling it in a loop is a bad idea

Not sure if I understand this ? I have checked as well the Documentation like

// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WEP network, SSID: ");
Serial.println(ssid);
status = WiFi.begin(ssid, keyIndex, key);

// wait 10 seconds for connection:
delay(10000);

}

If you considre it as wrong. How should it look like instead. I try 5 times to get connection. And this maybe all 10 minutes it I do not get a connetion.

[me-no-dev]

You are waiting only half a second in the example code above. That is rarely enough to connect to the WiFi
