Using WifiUdp.h on Arduino Mega and ESP8266?

Question

I was trying to run this library on Arduino Mega, using ESP8266 as replacement of Wifi Shield, as suggested on my older thread.

The problem is, I got error in compiling, after with this code :

#include <WiFiEsp.h>
#include <WiFiEspClient.h>
#include <WiFiEspUdp.h>


#include "AppleMidi.h"
APPLEMIDI_CREATE_INSTANCE(WiFiUDP, appleMIDI1);
....

exit status 1

'WiFiUDP' was not declared in this scope

if I modified the code into this :

#include <WiFiEsp.h>
#include <WiFiUdp.h>


#include "AppleMidi.h"
APPLEMIDI_CREATE_INSTANCE(WiFiUDP, appleMIDI1);
....

I got this error instead

C:\Program Files (x86)\Arduino\libraries\WiFi\src\utility\server_drv.cpp:313:40: error: 'WARN' was not declared in this scope

WARN("error waitResponse isDataSent");

                                    ^

exit status 1

Full code here at pastebin. I was pretty much stuck now. Please help! :(

Thanks :D

Answer 1

the WiFiEsp class for UDP is WiFiEspUDP

#include <WiFiEsp.h>
#include <WiFiEspUdp.h>
#include "AppleMidi.h"

APPLEMIDI_CREATE_INSTANCE(WiFiEspUDP, AppleMIDI);
