Error compiling for board ESP32 Dev Module - error: 'size_t SoftwareSerial::readBytes(uint8_t*, size_t)' marked 'override', but does not override

cara mengatasi cannot declare variable ‘server’ to be of abstract type ‘WiFiServer’

 downgrade versi board esp32

pengalaman ini error muncul setelah board esp32 saya upgrade ke versi 1.0.6

cara mengatasi masalah cannot declare variable 'server' to be of abstract type 'EthernetServer'

 If new arduino esp32 or make error, need go to c:\Program Files (x86)\Arduino\hardware\espressif\arduino-esp32\cores\esp32\Server.h

Change virtual void begin(uint16_t port = 0) = 0; to virtual void begin() = 0;
