Udp endPacket() returns -1 on error and 7 on success

[tonu42]

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.

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.

no worries :) things like that are important and easy to miss at the same time
