Serial connection to ESP32-Cam

[califax]

Hello,

with the arduino-ide I installed the camera-example on an esp32-cam-module. It works. The device is available in the network and you can see the pictures of the camera in the browser. In SerialMonitor the status messages (Serial.println) are displayed.

If you try to establish a connection with the program "miniterm" (from pyserial), then no status messages are displayed and the camera module is no longer accessible. The web server is not available and ping requests are not answered. If you exit miniterm, the module comes back to life,

Before starting miniterm the Arduino IDE was closed. When calling miniterm the same parameters were used as in SerialMonitor. (115200 baud and /dev/ttyUSB0).

The same happens if you use "screen" instead of miniterm.

I tested with a simple Hello World sketch. In this case the status messages are also displayed in miniterm.

Why does the camera example not work when trying to establish a serial connection with miniterm or screen?

tks
