I solved it by tagging the packets with NODELAY, setting the TOS and sending them OOB on the server side. Buffering must have happened at WiFi AP or ESP32. s.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1) s.setsockopt(socket.IPPROTO_IP, socket.IP_TOS, 0x10) s.send(message.encode(), socket.MSG...
