Welp I thought I was done posting about the Raspberry Pi 4 but I have to add one more thing.
I noticed my Bluetooth keyboards tended to be wonky - trouble staying connected and/or repeating keys. So today I borrowed a different keyboard to try and the same thing happens. After doing some research at the Foundation’s site it turns out there are a lot of reports of this. The RPi 4 has trouble with Bluetooth keyboards when used simultaneously with WiFi. Since June of last year. Because, you know, nobody uses those two things together.
Solution: Don’t do that.
Either use a USB keyboard or only use Ethernet. Or you can pay up for a RF keyboard with proprietary dongle.
It’s aggravating but I consider this defect more an annoyance than the throttling. Though it does further undermine the ‘desktop alternative’ claims.
Oh, in other news I built a small circuit that will turn the fan on when the CPU heats up. It’s amazing how annoying even a tiny fan can me in a quiet space.
