Missing TCPIP Lock in AsyncUDP multicast

[wladwnt]

Board

ESP32dev

Device Description

Custom ESP32 with ESP32-WROOM-32E-N4

Hardware Configuration

Not relevant

Version

v3.1.0

IDE Name

VSCode

Operating System

Windows 11

Flash frequency

40 MHz

PSRAM enabled

no

Upload speed

115200

Description

Call AsyncUDP.listenMulticast(addr,port) lead to reboot with message Required to lock TCPIP core functionality!
AsyncUDP.listenMulticast(addr,port) fails apparently because there is no TCPIP lock implemented for call igmp_joingroup()

No issue with v3.1.0-rc1 (before TCPIP lock introduced)

Sketch

#include "WiFi.h"
#include "AsyncUDP.h"

const char *ssid = "*******";
const char *password = "*******";

AsyncUDP udp;

AsyncUDP udp_multicast;
static const IPAddress SSDP_MULTICAST_ADDR(239, 255, 255, 250);

void setup() {
   Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("WiFi Failed");
    delay(1000);
  }
  Serial.println("WiFi connected");
  udp_multicast.listenMulticast(SSDP_MULTICAST_ADDR, 1900);
  udp_multicast.onPacket([&](AsyncUDPPacket packet) {
      Serial.println("Got packet!");
  });
}

void loop() {
  delay(1000);
}

Hello, we observe a same error after update to v3.1.0. Our code works fine with previous versions.

Hello, I have updated to v3.1.0 and same error occured. Previous version works just fine.

will be fixed. i guess we missed to add a lock somewhere
