- Sun Apr 19, 2015 5:08 pm #15069 I have the Arduino IDE up and running and flashing successfully to my ESP-12. However, if I select an upload speed higher than 115200, such as 921600, it will never flash successfully.

Is there anything special that must be done to use the higher flashing speeds?

Is this part suitable for those high speeds?
