Only receive udp multicasts which I transmit

[PeterR]

Using: /examples/protocols/sockets/udp_multicast

Configured the example to listen for a multicast which I know is transmitted by other devices on my network.
The example does not display the other device's multicast but happily displays its own broadcast (made when RX times out).

Code: Select all

I (386506) multicast: Sending to IPV4 multicast address 239.2.1.1:2054...
I (386506) multicast: received 28 bytes from 192.168.0.48:
I (386506) multicast: Multicast #37 sent by ESP32

Has anyone used this example and/or listened for a multicast?
