OPC for ESP8266 about opc

[ProximaB]

Yes, it works check the link https://github.com/ProximaB/OPC

1. Download OPC for Arduino from http://www.st4makers.com/ and open it with admin privileges.
2. Upload NodeMCU example to your Esp8266. Notice that you need to edit ssid and password of WiFi before).
3. Check what is the IP of Esp8266, you can use serial to obtain it.
4. In the OPC for Arduino add Ethernet and type I and port of your esp, save it.
5. Test if its working with eg. Kassl dOPC Explorer.Tip: This explorer works only if you put it in : C:\Program Files\Kassl\

Dear ProximaB

Thanks a lot for your support but still I am facing a problem in compiling the sketch for NodeMcu board it is giving a message during compiling.

exit status 1
'OPCNodeMcu" does not name a type

'OPCNodeMcu" does not name a type

i have the same issue... Any solutions.

I suppose that It doesn't linking proper OPC source files.
I'm not able to compile the code and run it but just for testing purposes and because opc is small library try following steps.
Copy OPC.ino and OPC.h to your current working directory and use it directly.

At that time I was using visualMicro for Visual Studio, it was great but I think it's not necessarily good thing to depends on that.

If you would like to help please fork my repo and clean that out. Thanks 😊

The OPC Master library in this link https://github.com/ProximaB/OPC has the file NodeMcu Example Sketch but not having the command for connecting the NodeMcu to Wifi or provision for setting up the ssid and password or IP.

@debashisiitbt check out this line of code myNodeMcu.setup("Internet_57", "123456789", 80);

Thank you very much. I managed to compile it and upload it to my esp8266.
It connects to wifi network and my Linux pc able to ping it. However when i try with UAExpert to connect, it fails to connect. (I changed the port to 4840). Am I missing something here?
