More simpel way off adding the ethernetmanager to my code

[dyrvigk]

Hi Khoih

sorry to ask what maby a stupid question but i am not a very good code writer and i have made some code for reading some modbus registers and post them as mqtt it si running on a esp32 i used to use wifi and wifimanager and wifimanager is not so dificult to add but now i have made my code with w5500 ethernet due to instability on wifi and would like to be able to setup my mqtt credencials like in wifimanager and i found your ethernet manager but to dificult for me to add to my code to many if for all kind off mcu is there a simpel way off just adding it similar to wifimanager my ethernet is already running i actualy only need to setup mqtt server mqtt user and mqtt password mqtt port right now i am doing hardcoded w5500nilan.zip

i have added my code

Thanks for your interests in the library which is a good choice for your use case.

I wish I had all the time in the world to help everybody, but in reality I don't have, So I'm sorry I can't spend time to help you to write the code.

This library is so simple to use, just have a look at the very similar examples to your case MQTT_ThingStream_Ethernet_Generic, and I think you can figure out how to modify your code by yourself.

If not successful, I suggest you ask for help from a forum or a professional code writer.

Good Luck,

[dyrvigk]

Ok Thanks for your response I will try to figure it out and see if I can get it simplied alittel

Hi Khoih

i am back asking for a littel help i have gotten my code implemented in your exampel code and i also have gotten it to compile but unfortnatly the esp just reboots all the time with some exception or do you have any idea who could help me

best regards kenn

[khoih-prog]

First, try to post the whole code and ask for help in Arduino Forum's Programming Questions where there are many good experts ready to help you out.

Finally, if you try without success, you can post the whole code here so I'll try to find the time to help.

Good Luck,

Hi Khoih

thanks i have posted it on forum as you asked first response was that probably is because of last library installed ESP_doubleresetdetector was the last but if i compile just your example it runs if i compile just mine it runs but together i compiles but dont run so if you have 5 min to tell me if it is done totally wrong sorry to bather you with my ignorance i dont know much about coding got started in a late age but you have to learn as long as you live

i have attached the my code with ethernet thats is working but no ethernet manager and my code in your example ethernet_generic that gives this exception

HI,

I'm sorry I can't help you anything here.

I already tried to look at the code you post here as well as in Arduino Forum and even can't compile as well as understand anything there.

I estimate anybody working on your code must spend weeks to figure out, not 5 minutes as you expect. And not everybody has the same settings as you have.

I suggest that you start with a simple working example. Then add more code gradually, then test to see if OK, and moving forward, small steps by small steps.

If you still can't figure out, I suggest you hire some professional coder to write for you.

Good Luck,

[dyrvigk]

ok thanks anyway is there a way to use just the ethernetmanager likewith wifimanager without all the ethernet code since i already have that part running

Yes. The example is written for too many kind of general Ethernet shields and boards. You just remove whatever not applicable to you to simplify the example when you know what Ethernet/board you're using.

ok i am using esp32 and ethernet2

You have to do it by yourself, step by step through the target example. Sorry.

hi again sorry to bather you but maby you know how to fix this small problem i have i would like to use wifi and ethernet on esp32 but it is not possible because off server.h

Did you have a look at and try this For fixing ESP32 compile error

---

7. For fixing ESP32 compile error

To fix ESP32 compile error, just copy the following file into the ESP32 cores/esp32 directory (e.g. ./arduino-1.8.12/hardware/espressif/cores/esp32) to overwrite the old file:

• Server.h

[dyrvigk]

yes i did that but how do i get both options possible because with that change wifi wil not compile because uses same server.h

Post a MRE code here as well as on ESP32 forum to ask for help. Nobody can have a crystal ball good enough to guess and help you unless you post your MRE code.

If not, please work and solve the issue yourself.

Why don't you go back to a simplest working code, then move forward? Compile for both WiFi + Ethernet on ESP32 is not new.

Hi Khoih

If compiling for both wifi and ethernet w5500 is not new could you please point me to a example because i have had trouble finding it

Hi Khoih

just a small update i finally found the solution using wifimanager to setup my mqtt credentials and using ethernet for the connection to mqtt server after long time looking i found this workaround for the server.h file /* Server.h - Base class that provides Server Copyright (c) 2011 Adrian McEwen.

thanks for your time and for the push to look more unfortnatly the ethernet manager or some other libary needed is nor compatibel with my code or some off the libaryies needed

That's good. But you waste your time by not looking at the link I gave you

7. For fixing ESP32 compile error

To fix ESP32 compile error, just copy the following file into the ESP32 cores/esp32 directory (e.g. ./arduino-1.8.12/hardware/espressif/cores/esp32) to overwrite the old file:

• Server.h

#define server_h

    //virtual void begin() = 0;
    void begin() {};
};

#endif

Another hint for you.

WiFi and Ethernet Bridge? #26

[dyrvigk]

actualy i did look at your file i even put it in but i had to add this line to get my code to compile

void begin(uint16_t port = 0) {};

i am not making a bridge just using wifimanager for setting my mqtt credentials via wifi ap
