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
