I have been trying to get debugging over wifi to 
work on my esp12x(esp8266) chip.
But i am not able to get this working.
Is it possible to do this on this chip?
and how do i solve this?

Hope someone can help me on this one.
Just started with Visual Micro.

The latest release 20.06.30.1 contains the update to resolve the issue, which is the latest release at the top of the below board:
https://www.visualmicro.com/forums/YaBB.pl?board=VS_ARDUINO_EXT_RELEASES

If you have trouble installing this release please see this Video Guide for this process.

Essentially the same problem. I am unable to OTA upload or debug on an ESP-12E. 

I have updated to the latest vMicro release (2020.910.14). 

I am testing using the example code from the link below:

https://www.visualmicro.com/page/esp8266.aspx

I have bonjour installed on Windows 10 and the IP of the chip shows up in Visual Studio.

I also have a local boards.txt file. Initially I was having authentication issues so added authentication to boards.txt and set OTA password in the example code. Contents of boards.txt:
 
# local project board.txt overrides
network.password=123
network.auth_upload=yes
  network.port=8266

That got me past the auth issue, but now I get the following output:

I can successfully upload and debug over serial interface. I uploaded the example app initially over serial before attempting other OTA operations.

Thanks for the quick response. Will do.

Thanks for the detail.

Do you have a firewall enabled on your machine, and if so have you added the port as an exception to the list?

If its the standard Windows Defender Firewall, you can add an exception for Python3 on your Private Networks to resolve this.
(The path to the Python3.exe can be grabbed from the output, if you enable vMicro > Uploader > Verbose and try the upload again)

Hi.
Make sure you have "Erase Flash: All flash contents",
so you don't have any "left overs".
Did not change anything else in project properties.
I tested on a ESP12(ESP8266).
pc og ESP12 on same network.
this sketch worked for me:

#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <WiFiUdp.h>
#include <ArduinoOTA.h>
const char* ssid = "SSID";
const char* password = "PASSWORD";
void setup() 
{
    Serial.begin(115200);
    Serial.println();
    Serial.println("Booting");    
    WiFi.begin(ssid, password);
    while (WiFi.waitForConnectResult() != WL_CONNECTED) 
    {
        Serial.println("Connection Failed! Rebooting...");
        delay(5000);
        ESP.restart();
    }        
    ArduinoOTA.begin();
    Serial.println("Ready");
    Serial.print("IP address: ");
    Serial.println(WiFi.localIP());
}
void loop() 
{
    ArduinoOTA.handle();
}
