XIAO ESP32S3 Sense does not work when not connected to computer

I can get the ESP32S3 Sense with camera to work as long as I’m connected to the computer (Linux). Both LEDs turn on when the program is running.

However, when I try to run the camera just on a USB-C cable/wall wart (which I would consider to be normal operation), only the red LED comes on and the web server never tries to connect to my network.

When I reconnect to my main computer, most of the time, the device reconnects to the network and I can access the webserver again.

Any thoughts?


Does the sketch require a serial connection?

While (!Serial);

I never thought of that.
It worked perfectly.
