Never Mind. Re: Bluetooth pairing of Logitech K830 keyboard with Pi-4B: anyone done it?

Never mind. In reviewing my posting, I saw that I hadn't "trusted" the ...:F8 device. Did that, paired with the device again, and it works fine.

So the answer is: Yes, the Logitech K830 keyboard works as a bluetooth device off the RPi-4B.

Bluetooth pairing of Logitech K830 keyboard with Pi-4B: anyone done it?

I have a lovely Logitech K830 keyboard that I can't get paired with my RPi-4B as a Bluetooth device . It works fine with the "unifying receiver", but I don't want to take up a USB slot with that dongle. "bluetoothctl" sees the keyboard, knows its address, and knows it's a "K830" device. But attempts...

Re: Raspberry Pi4 EEPROM update package - beta

Ernst, thanks for the further explanation. With that I was able to update the firmware successfully. I was, indeed, booting from the µSD but redirecting to a USB drive, and fstab on that USB drive mounts /boot from the USB drive. "rpi-eeprom-update -a" did put the update files in /boot, but on the U...

Re: Pi Zero Buster OTG to OSX Mojave setup tips?

Incidentally, you should be able to connect to your Pi over wifi even if the USB link is connected. Just use the IP address of the wifi interface rather than the Pi's hostname. Yes, it was convenient to be able to log in via WiFi to fix the usb0 configuration settings, even though the usb0 port was...

Re: Pi Zero Buster OTG to OSX Mojave setup tips?

Ah, one small wrinkle. With the "interfaces" above, if you boot without the OTG connection, it boots fine but the Pi Zero can't get out to the rest of the world because 192.168.2.1 isn't connected. I thought the syntax was that the gateway spec would apply only to the usb0 interface, but it apparent...

Should also note that yesterday's update to openSUSE aarch64 Tumbleweed, from 5.1.3 to 5.1.5 on the RPi-3B+, also fixed the problem there.
