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!");
});
}
