Dual Mode: Wi-Fi Station + AP with Multicast UDP

[prem111as]

Hi, is it possible on an ESP32 to be connected to a Wi-Fi AP while simultaneously creating our own AP (i.e., dual mode), and then send multicast UDP over that created AP?

An ESP32 running MicroPython can act as both a Wi-Fi creator (Access Point) and a Wi-Fi client (Station) at the same time. It creates one network (Na) and connects to another (Ns). Devices on Na can communicate with each other via UDP multicast, but the ESP32 will not automatically pass that traffic to Ns. To share multicast data between the two networks, you must program the ESP32 to manually forward packets from Na to Ns, and vice versa.
