On the Pico W:
import struct, socket
def inet_aton(addr):
return bytes(map(int, addr.split(".")))
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(("", 5007))
s.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, struct.pack(">4sI", inet_aton("224.1.1.1"), 0))
print(s.recvfrom(1024))From a PC:
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 2)
s.sendto(b'some data', ('224.1.1.1', 5007))
s.close()
This same code works fine when the receiving device is an ESP32. On the Pico nothing is received.
