Sparkfun ESP32 Thing - can't get example sketches to download

I’ve search numerous websites trying to get a simple program to download from the Arduino Ide. I have tried numerous download speeds, programmers, etc.

I keep getting timed out waiting for packet header

Any suggestions?

Hello,

Just to clarify, are you having difficulty uploading code from the IDE to the ESP32 Thing or are you unable to download from the internet using the ESP32 Thing?
