Program ESP32 module Error: Timed out waiting for packet header

Postby Rob5836 » Wed Nov 06, 2019 11:24 am

I have the esp32 wroom32 module on a custom PCB board. Every time I try to program it with the arduino IDE, ESP32 board version is the vroom module. When I try to program it a I get the following error. I have also attached the summary below. Any help would be greatly appreciated.
