Blink led on master request

[nex2000]

Hello I'm not very good at programming , but i'm using this library with great results it works great, kudos to the author.

i couldn't catch the event to make a led turn on or blink every time the master sends a request. Could anyone help me? I attach the source

Regards

`#include <WiFi.h> #include <ModbusIP_ESP8266.h>

const int relayCtrlPin = 2; const int tempPin = A3;

const char ssid []= "--------------------"; const char password []= "--------------";

ModbusIP modbusTCPServer;

void setup() { Serial.begin(115200); pinMode(relayCtrlPin, OUTPUT); digitalWrite(relayCtrlPin, LOW);

Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); }

Serial.println(""); Serial.println("WiFi connected."); Serial.println("IP address: "); Serial.println(WiFi.localIP());

modbusTCPServer.slave(502); modbusTCPServer.addCoil(0x00); modbusTCPServer.addHreg(0x00); }

void loop() { modbusTCPServer.task(); digitalWrite(relayCtrlPin, modbusTCPServer.Coil(0X00)); modbusTCPServer.Hreg(0X00, analogRead(tempPin));

delay(10); } `
