esp8266 to m5stack wifi communication

[cepics]

Hi, Im looking for a way to port my "espnow esp8266 to esp8266" project to m5stack
I'm using arduino core
I need to send a sensor value from esp8266 to m5stuck as faster as possible

this is my sender code: (sorry I can't find how to insert code)

// EspnowController.ino

// a minimal program derived from
// https://github.com/HarringayMakerSpace/ESP-Now

// This is the program that sends the data. (The Controller)

//=============

#include <ESP8266WiFi.h>
extern "C" {
#include <espnow.h>
}

// this is the MAC Address of the slave which receives the data
uint8_t remoteMac[] = {0x36, 0x33, 0x33, 0x33, 0x33, 0x33}; //se cambia il MAC ADDRESS ricordarsi di cambiare anche il serial print per poter clonare il modulo

#define WIFI_CHANNEL 4 // se cambia il canale ricordarsi di cambiare anche il serial print per poter clonare il modulo

// must match the slave struct
struct attribute((packed)) DataStruct {
char text[32];
unsigned long time;
};

DataStruct myData;

unsigned long lastSentMillis;
unsigned long sendIntervalMillis = 10;
unsigned long sentMicros;
unsigned long ackMicros;

unsigned long lastBlinkMillis;
unsigned long fastBlinkMillis = 200;
unsigned long slowBlinkMillis = 700;
unsigned long blinkIntervalMillis = slowBlinkMillis;

byte ledPin = 14;
/////////////////////////////////////////////////////////
#include <NewPingESP8266.h>
#define TRIGGER_PIN D5 // 14 Arduino pin tied to trigger pin on the ultrasonic sensor.

//#define MAX_DISTANCE 350 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

void setup() {
Serial.begin(115200); Serial.println();

void loop() {

void blinkLed() {

and this is my rx code:

//=============

// it seems that the mac address needs to be set before setup() is called
// and the inclusion of user_interface.h facilitates that
// presumably there is a hidden call to the function initVariant()

/* Set a private Mac Address

Note: by setting a specific MAC you can replace this slave ESP8266 device with a new one
and the new slave will still pick up the data from controllers which use that MAC

uint8_t mac[] = {0x36, 0x33, 0x33, 0x33, 0x33, 0x33};
