I’m receiving the following message when I boot up my Heltek Kit 32

When I compile it get this message:

Uploading ‘Tanks’ to ‘WiFi Kit 32’ using ‘COM10’
esptool.py v2.6
Serial port COM10
Connecting…………………_____
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
esptool.py v2.6
Serial port COM10
Connecting…………………_____
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

The uploader returned an error

Seems like I need a new bootloader.

Can anyone offer guidance?

Thanks

Hi,
Is there any other device connected to the computer, and whether the serial port is selected correctly?

Yes there are others but they have been there all along. I have another WiFi 32 that I plugged into the same USB and it operates fine. This WiFi 32 has been working fine for months as I built out my code. It just suddenly jumped into this problem
