Hi,
I use the combined ESP8266+ATMega board in my attempt to learn and control the ESP8266.
The board is set to USB+esp (only, no ATMega used)
The esp is flashed and active, AT commands are OK.
I now wish to load to the esp the Arduino IDE prepared esp control program by Yavnik (https://cdn.instructables.com/ORIG/FCX/SCY8/IR85H83Y/FCXSCY8IR85H83Y.ino), but not sure what the correct procedure is.
ESP8266WiFi.h is included in the Arduino IDE, the generic esp8266 is selected.
When loading the program, the serial R/T Leds blik, but after several attempts I get the error:
