While aiming to make this little thing fully mobile, I kept searching for USB-compatible li-lon batteries and a palm-sized usb keyboard.
Tried setting up the bluetooth keyboard as a boot-up device, it seems I picked something not too suitable. Had difficulties setting up auto connection between the ProMini and Raspi… bluez library didn’t seem well documented, maybe it doesn’t even provide auto-pairing?
Don’t mind writing my own service for this, but first let’s make sure the bluez really meant to leave it to developers. 😐
