ESP8266 - COAP with DTLS support required

I wrote following code using ESP8266 ESP-01. I have used CoAP protocol which runs over UDP. I now want to use CoAP with DTLS. Is there any support in ESP, please let me know ?

#include <SPI.h> #include <ESP8266WiFi.h> //http server library #include <WiFiUDP.h> //udp library #include <coap.h> const char* ssid = "AndroidAP"; const char* password = "abcde12345"; byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 }; IPAddress ip(192, 168, 43, 7); // CoAP client response callback void callback_response(CoapPacket &packet, IPAddress ip, int port);

// UDP and CoAP class WiFiUDP Udp; Coap coap(Udp);

// CoAP client response callback void callback_response(CoapPacket &packet, IPAddress ip, int port) { Serial.println("[Coap Response got]");

char p[packet.payloadlen + 1]; memcpy(p, packet.payload, packet.payloadlen); p[packet.payloadlen] = NULL;

Serial.println(p); }

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

if (WiFi.status() != WL_CONNECTED) 
{
    delay(1);
    // Connect to WiFi network
    Serial.println();
    delay(10);
    Serial.println();
    delay(10);
    Serial.print("Connecting to ");
    delay(10);
    Serial.println(ssid);
    delay(10); 
    WiFi.begin(ssid, password);
    
    while (WiFi.status() != WL_CONNECTED) {
      Serial.print(".");
      delay(500);
    }
    Serial.println("");
    Serial.println("WiFi connected");
    
    // Print the IP addres 
    Serial.print("ESP8266 IP: ");
    Serial.println(WiFi.localIP());
  
    //Serial.print("ESP8266 WebServer Port: ");
    //Serial.println(SVRPORT);
    delay(300);
}

// client response callback. // this endpoint is single callback. Serial.println("Setup Response Callback"); coap.response(callback_response);

// start coap server/client coap.start(); }

void loop() { // send GET or PUT coap request to CoAP server. // To test, use libcoap, microcoap server...etc int msgid = coap.put(IPAddress(192,168,43,7), 5683, "sensordata","temp 23 humid 35"); Serial.println("Send Request"); // int msgid1 = coap.get(IPAddress(192, 168, 43, 7), 5683, "time");

delay(1000); coap.loop(); }
