hey guys, have now set up my first device (T-Beam) and it runs after a firmware flash everything fine. The second device makes me now but quite problems…when I want to install the new firmware comes constantly the message:
“Unexpected error: ESP Chip Auto-Detection failed: Failed to connect to Espressif device: Timed out waiting for packet header”.
Also, the buttons on the device can not be operated. Neither Reset nor Power works. After inserting the battery, the red LED lights up briefly and then the blue LED lights up permanently.
Does anyone know the problem?
FYI: My device has no display
