Basic Infos
Hardware
Hardware: ESP-12
Core Version: 2.4.0-rc2
Description
ESP will crash and reboot when ArduinoOTA is enabled and a udp packet of any size is sent to the port used by ArduinoOTA. In fact, even just a nmap scan of the port will cause a crash (ex: nmap -sU -p 8266 192.168.1.212)
Settings in IDE
Module: WeMos D1 R2 and mini
Flash Size: 4M (3M SPIFFS)
CPU Frequency: 80Mhz
