Re: MySQL Verbindung

Als Resumee: Man lernt nie aus. Ich hatte keine Ahnung was Snap-Installation bedeutet. Die Fehlermeldungen wegen der shared object files würde ich nicht überbewerten. Die kann man ziemlich sicher durch irgendeinen Hack wegbekommen. Problematisch ist, dass durch Snap-Pakete und Distributions-Pakete d...

Re: Connect 2 bluetooth speakers to a RPI4

I installed the bluealsa package and used bluetoothctl (sudo bluetoothctl) via ssh. In Raspbian with Desktop this package is preinstalled. But it's impossible to use blutooth and analog speakers at the same time with the desktop app. If you select "Analog" the bluetooth speaker gets disconnected. I ...

Re: Connect 2 bluetooth speakers to a RPI4

If you started with Raspbian Buster and your card is a micro SD card - yes, you could simlpy plug your card and SSD into a Raspberry Pi4.

Re: Swapping SD cards between models

If you are installing Raspbian on a Raspberry Pi4, it will run on a Raspberry Pi3 too.
If you manually edit config.txt, you should be aware, that the section between [pi4] and [all] applies only to Raspberry Pi4.
Of course a WiFi configuration for 1st location may not work for 2nd location.
