Fehler ESP32: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

20.05.2020 (👁8091)


Ursache:

Wenn der PIN EN auf GRD verbunden ist oder GPIO0 G0 auf 3,3 Verbunden ist

Verhalten:

Beim Upload eines neuen Programms Sketch bleibt der Upload-Vorgang hängen mit der Meldung

Connecting........_____....._____....._____....._____....._____....._____.....____An error occurred while uploading the sketch

 

 

 

Lösung:

Entweder mit einem kleinen Kondensator oder einem Pullup Widerstand auf das andere Level ziehen

Im Serial Monitor

Sketch uses 211501 bytes (16%) of program storage space. Maximum is 1310720 bytes.

Global variables use 15428 bytes (4%) of dynamic memory, leaving 312252 bytes for local variables. Maximum is 327680 bytes.
