There was a change in the USB handling recently, leading to more reliable registering of the device. So it might be worth trying the update.

Which firmware version is installed on the Pico?

Add the line

global sendung

after 'wlan.connect('ssid', 'password')' the connection does not happen immediately. You have to wait until the device is connected, checking with wlan.isconnected(). You can set the ip address before calling wlan.connect(). Then that one is used right from the start. P.S.: That's the script I use a...

So led.off() should switch the led on, and the opposite. But it should switch. I prefer to specify the...

Please tell us,

- which RGB led you are use
- how you connected it to the ESP32 board and
- which python commands you used.
