I'm trying to send UDP multicast packets as fast as possible from the RPi5 (builtin wlan) to a ESP32-S3. The latter is reported to support UDP throughput of 30 Mbit/s (https://docs.espressif.com/projects/esp ... /wifi.html)
The wlan network is dedicated for this only so there's no other traffic on it. However, my tests choke at sending UDP packets each 5.333 ms with > 128 bytes per packet, after which I get packet losses, and this is nowhere near my required packet size (of ~1000 bytes) and it is also roughly 240 kbits/sec, nowhere near the capacity of the ESP32-S3.
I am not sure at all what the wlan multicast bitrate is though, and this is my question. How can I twist the RPi5 wlan interface to crank out multicast UDP packages with at least 30 MBit/s ?
