[WiFiEsp] Data packet send error (2) [WiFiEsp] Failed to write to socket 3 [WiFiEsp] Disconnecting 3

You need to get into EspDrv.cpp and increase the timeout values such that send and receive events have longer to complete.

With my wifi irrigation controller I have noticed regularly that send and receive events are very snappy when the controller is operating at some of my clients premises. But it is quite slow (and still times out even after I hacked the library) when operating at home.

I suspect you have the same problem that I have in my home in that the Wifi coverage is not optimal that leads to these timeout errors

Musisz wejść do EspDrv.cpp i zwiększyć wartości limitu czasu, tak aby zdarzenia wysyłania i odbierania miały więcej czasu do ukończenia.

Dzięki mojemu kontrolerowi nawadniania Wi-Fi regularnie zauważyłem, że zdarzenia wysyłania i odbierania są bardzo szybkie, gdy kontroler działa w niektórych lokalizacjach moich klientów. Ale jest dość powolny (i nadal się kończy, nawet po zhakowaniu biblioteki) podczas pracy w domu.

Podejrzewam, że masz ten sam problem, który mam w moim domu, ponieważ zasięg Wifi nie jest optymalny, co prowadzi do tych błędów przekroczenia limitu czasu
