Hi there!  
I thought, that would be an easy one, but it turned out to be tricky instead.  
My project depends on a Bluetooth BLE keyboard connected to a Raspberry Pi Zero W 2 running the 64 bit arm version (released March 2024) of Raspbian.  
Actually, there are 8 BLE keyboards connected, that all have a single key each (buzzers).  
While it doesn't seem to be a problem to get events from USB HID keyboards, BLE HID keyboards are not recognized by rpi-keyboard. The window holding the focus will get key events but the keyboard node won't catch the key event.  
I don't need dedicated key-press and key-release events but simply the fact, that a key was pressed at all. Having the key code or character would be a nice add-on but is not necessarily required.  
Is there a node available, that would allow to catch BLE keyboard events?

Thanks in advance,  
Helge

Indeed - the pi-keyboard node just looks for a single kbd device under /dev/input/by-path/ BLE devices probably attach themselves to some other path, a BLE node or HID node may be more appropriate.
