After some time of struggle to get a PlatformIO sample to compile for an Arduino Mega I finally peace together by downloading the arduinoWebSockets/tree/ATmega branch and copied it to the libdeps folder. I was not able to uncover what "lib_deps = ###" to add to my platformIO.ini file to get it to automaticaly add the resource to the project.

Anyhow to the primary reason I came back here. I'm building this project on a mega because I do require the additional IO the Mega has. In a previous project on an ESP32 the payloads I receive are large and usually get split across the webSocketEvent(WStype_t WStype_FRAGMENT where I concatenate the payload back into the JSON file I expect.

It seems this libray only has the following types included

typedef enum {
 WStype_ERROR,
 WStype_DISCONNECTED,
 WStype_CONNECTED,
 WStype_TEXT,
 WStype_BIN
} WStype_t;

Is there a reason for the short list?
