Every time in process of adding server in dOPC, ArduinoPOCServer.exe get crashed and unable to established connection.

Hi,
First i want to congratulate you on excellent work done.
I noticed during testing that if I give a listen port number greater than 255 then item browsing fails.
However the default 80 and anything less than 255 works. Is there anything wrong i'm doing?

I installed the OPC Server and I am trying to view the items in Matrikon OPC Explorer. I can see the server and can successfully connect to it, however no items are visible. The logging from the OPC Server shows the following:

18-Mar-19 13:35:44 > Running OPC Server from C:\Users\Djim\Downloads\ArduinoOPCServer.exe
18-Mar-19 13:35:44 > Waiting for OPC clients to connect....

18-Mar-19 13:36:21 > Asking for available OPCItems from ArduinoSerial0

On the last line it should send an overview with available fields, as I concluded from some of the video tutorials. Unfortunately it's blank... Any help would be greatly appreciated

ESP8266 resets when i try to change status of pin D6,D7 and D8. The pin mapping shows D6 as gpio12, D7 as gpio13 D8 as 15; I am using ESP library version 2.5.2. I think this might be conflict between Ethernet.h and ESP8266WiFi.h library. When it restarts there is not startup message. I tested it with dOPC explorer 2.0.0.261 and ArduinoOPCServer version 2.0, i also tesed it via browser the esp32 restarts without sending the response code back to the browser webpage. i am thinking of porting the code to work without the OPC library to avoid any conflics for both esp8266 and esp32.

This is an awesome work! I just recently bought the Lolin NodeMCU V3 Board which has an on-board WiFi and quite a small footprint. I was wondering if I could port this project to that board. What is your plan so far as to the License of the Source Code? Can I freely port it to other board and sell the board? Personally I don't mind sharing the ported source code.

Why it is impossible to use Arduino OPC Server with Arduino Micro?

Hello,

I need to write my own OPC server like this for data transfer with arduino. 
Any ideas which subjects should i research and what should i follow ?

Hi,
I want to expand your OPC library with ESP8266 support. I finally set up everything and understand library code and will write core connection in this week. 22/05/18
