I get this warning message:

[WiFiEsp] Warning: Unsupported firmware 3.0.4

Library work but show this Warning on Serial monitor

My ESP-01 module AT version:

use my WiFiEspAT library

[makarna35]

use my WiFiEspAT library

Your library compitable with mathworks/thingspeak-arduino ?

It is an Arduino WiFi library like the WiFiEsp, but it doesn't support SSL with AT 1.7.4, only with 2.1.0+.

@JAndrassy Does your library support DNS?
I like to set Statip IP and whilst you can do this with WiFiEsp with Config.begin(IPAddress, ssid) that's all it does allow.
It doesn't allow setting gateway, netmask or DNS, it's the DNS that is important for me.

I'm already guessing the answer is no, impossible because the AT Command Set doesn't support it. Am I right?

Thanks for the reply.
Just tried your fork, however it throws up error when compiling.
Error compiling for board Arduino Mega or Mega 2560.
The original WiFiEsp compiles fine.

and what do you compile? and what compilation error?

[Legsmaniac]

This is my original code as it stands at the moment, it's part of a larger project.
Naturally, I changed the line #include "WiFiEsp.h" for #include "WiFiEspAT.h" and also tried #include <WiFiEspAT.h> but it doesn't like it when compiling for Mega2560.

install WiFiEspAT from Library Manager and try the examples

[Legsmaniac]

It's already installed but good point, I'll try one of the examples..............

[Legsmaniac]

Right, test passed.
Investigating further, it looks like it may well be the #include "WiFiEspUdp.h" that is the problem as this is calling for WiFiEsp-Master. Yet if I rename it #include "WiFiEspATUdp.h", it throws a wobbly.
Thoughts?

[Legsmaniac]

I could try re-writing my project and use Time.lib instead I guess.

[JAndrassy]

UDP is included with #include <WiFiEspAT.h>
WiFiEspAT.h is a wrapper to identify the library. all the other files don't have EspAT in name.

Note: WiFiEspAT is not a fork of this library. It is original code with a very different and more robust concept of 'driver'

[Legsmaniac]

UDP is included with #include <WiFiEspAT.h>

Hmmmmmm. Why then won't it compile for me? As mentioned above, I have WiFiEspUdp.h yet it gives me this error when I attempt to compile......

XmasClock:3:10: fatal error: WiFiEspUdp.h: No such file or directory
 #include <WiFiEspUdp.h>
          ^~~~~~~~~~~~~~
compilation terminated.
exit status 1
WiFiEspUdp.h: No such file or directory

I have tried both "WiFiEspUdp.h" and <WiFiEspUdp.h> and both fail.

[JAndrassy]

please read again my previous comment

[Legsmaniac]

please read again my previous comment

I did.
You said "UDP is included with #include <WiFiEspAT.h>".
So from that I take that to mean UDP should still work,
However you also say "Note: WiFiEspAT is not a fork of this library."
Do I assume from this that WiFiEspUdp therefore doesn't work and it's some other command?
If I then try commenting it out, the following doesn't work .....

WiFiEspUDP ntpUDP;
NTPClient timeClient(ntpUDP);

So what are the required commands I now need to use instead please? I can find no documentation on it.

[JAndrassy]

I can find no documentation on it.

really? there are examples in IDE Examples menu. there is documentation link in Library Manager. so usual places.

the common Arduino UDP example UdpSendReceiveString has a version for WiFiEspAT, which has only

#include <WiFiEspAT.h>

at the top. there is no WiFisomethingUdp.h.
if you look in the folder with the library or list the files on GitHub, or if you look into the .h files you will immediately see that the Udp include is named WiFiUdp.h, but it is included in WiFi.h which is included in WiFiEspAT.h so you don't have to include it in the sketch.
