Re: Bluetooth range

I have a Logitech K380 Bluetooth keyboard. I use it with a RPi 4B 4GB with Raspbian Buster. The keyboard worked fine until one time a program I had crashed. I had to shut down the Pi using the power switch. It booted OK after that but the Bluetooth keyboard would not connect right after that. I fina...

This isn't exclusively a Pi 4 issues. I experienced the same thing with a Pi3 at code club last weekend. I was able to import a background from the background editor rather than via the normal import button. I haven't had a chance to figure out what the issue is however. I figured out what the prob...

Re: raspberry pi4 freeze while trying to upload astronaut backdrop

You did not say what version of Scratch you are using. I assume you are using Scratch 2 since that is what is talked about in the Beginner's Guide v2. I tried the same thing using Scratch 2 on my Pi 4. I was surprised to see that my Pi also hung just like yours. It probably was not the best thing to...

Re: Am I the only one that still would buy a Raspberry Pi 3b+?

What's a Pi 4? 20 watts maximum? That's $50-$100 a year in electricity. Peanuts for 24/7 usage of a device So you do fully confirm my statement "A Raspberry Pi running 24/24 costs in a year more electricity than its hardware value." And a Pi 3B+ costs definitively less than a 4B. Every year. That's...
