Glad to have helped. Glad I was not mistaken. This was my first ever issue I reported on Github! Trying to be involved with the ESP32 development to make it better for everyone. Hope you did not think I was nitpicking. |

Been using Udp a lot and believe when the packet fails to send successfully it should return 0, and on success a 1.
From cores/esp32/Udp.h
// Returns 1 if the packet was sent successfully, 0 if there was an error virtual int endPacket() =0;Below screen shots to support.
