Fix server.send buffer size limited to 4k

[khoih-prog]

Created by @jlemieux55 as server.send buffer size limited to 4k #23

html file or message is > 4500 bytes
server.send buffer truncates at > 4096
String message="";
message+=("html content is over 4500 bytes");
server.send(200, "text/html", message);

Platform: Arduino MKR1010 (wifinina)

Closed via WiFiNINA_Generic v1.8.15-0 which permits sending much larger data than total 4K.

Hi @jlemieux55

Did you try the new WiFiNINA_Generic v1.8.15-0 ?

If not working, it's possible that you have MKR1010 and that board actually uses WiFi101 library.

WiFiNINA_Generic/src/WiFiNINA_Generic.h

Lines 49 to 54 in 1ca8d81

	#if ( ( defined(ARDUINO_SAMD_MKR1000) || defined(ARDUINO_SAMD_MKRWIFI1010) ) && USING_WIFI101 )
	#include <WiFi101.h>
	#warning Using WiFi101 Library for MKR1000 and MKRWIFI1010 in WiFiNINA_Pinout_Generic.h
	#else
	#include "WiFi_Generic.h"
	#endif

If you're willing and have time to test, I can also modify the forked-WiFi101 library, to provide the similar feature, to send large data.

The current problem for me is that I have no MKR1010 to test and verify, and don't like to buy that outdated board.

Just let me know.
