Do you know anyone in New Zealand that could help?

Hi.
That error means that the computer can’t establish a serial connection with your board.
- Check that you have GPIO 0 connected to GND.
- TX connect to RX
- RX connected to TX
What’s the FTDI programmer that you have?
Without further information, it is very difficult to find out what might be wrong. But usually, it’s due to a wrong connection.
If you want to find someone near your location to help you out, it would be better to ask in the facebook group: https://www.facebook.com/groups/RandomNerdTutorials

HI Sara,
I have a
ESP32 TTGO T-Camera with PIR Sensor and OLED Display Board.
That I can get to threw a web browser at http://2.2.2.1 and this works fine. However when I try to upload a sketch I am getting the "a fatal error occurred: Failed to connect to esp32: Timed out waiting for packet header".
Am using windows 10 and followed the guidelines you set out on this page.
https://makeradvisor.com/esp32-ttgo-t-camera-pir-sensor-oled/
I can connect the USB directly into the TTGO. Can you make any suggestions, please?
Regards
Garth

Hi.
Can you try pressing the RST button right before uploading the code?
