After having used ArduinoOTA for years, literally, to upload firmwares to a couple of ESP8285 and NodeMCU devices, out of a sudden OTA has stopped working for me.
At the same time, the device will report (in the onError() callback) "Error[1]: Begin failed" on ESP8285 and "Error[4]: End failed" on NodeMCU devices. Next comes the AUTH request from the device: Finally one last packet from This looks OK for all I know, but why does ArduinoOTA stop here?
What may cause this issue? |

Found it and will open an issue for it. Problem is the unreliable UDP transmission of the short "OK" packet as soon as the authentication was successful. |

What version of the core was making the update ? UDP should really be replaced by TCP as a non-breaking extension in this OTA process... |

The core version is 2.6.3 AFAIK. I will add my observations to 6369. |

Hi, I get a similar error with the latest versions. I currently cant even get the BasicOTA to update via OTA. It fails at 0% uploaded and the above mentioned "Error[4]: End failed". Any tipps on how to get this working? |
