Why are UDP packets on port 53601 sometimes sent and visible in Wireshark, but at other times they are not sent? What factors could influence the intermittent transmission of these packets?

I am sending udp packets from stm32f427 mcu

Is the destination on the local subnet? If yes, that will rely on arp to resolve the destination IP to a MAC address to send the UDP datagram.
