Hi all !

Welcome to another update.

This is part of a challenge - 31 days of Raspberry PI 400 . This challenge consists of me using the Raspberry PI 400 and nothing else, for 31 days !

 

Zoom and Raspberry PI JAM

 

Yesterday was the Raspberry PI JAM Of Castelo Branco, promoted by the Associação de Informática de Castelo Branco (Computer Association of Castelo Branco) .

The Meeting was online, in a Zoom session.

 

Like before, I knew that a Zoom APP doesn't exist for Raspberry PI arm. Chrome has an App, but I can't work with it, because it just stays there connecting and won't move forward. I have to use the browser instead.  Both chromium and Firefox work.

Like I had tested before, the USB camera doesn't work on Firefox, but this time, there was a part of the meeting I didn't needed it, so, Firefox could be an option for that part - but we will get there in a bit.

The meeting started fine, but along the way, it gets starting slow. The camera freezes - but not the sound. People complained that the camera freezes. Even in the preview, it skipped a lot, but a lot of frames. It was not good.

After a while, I needed to share my screen. Not Chromium nor Firefox were able to do it. Zoom says it's sharing the screen, but all the participants see is my name on a black background.

Amazingly, the sound never failed. image  The camera microphone worked flawlessly.

 

That's a pity. I thought that the Raspberry PI 400 could be used for remote work and meetings, but this problems make this unusable. I don't know if it was the camera .

NOTE: I realize now that I didn't have the camera (and never had it in previous uses) connected to a USB 3.0 port. Could this be the root of  the problem ? Will test this in future meetings. Although, even watching Netflix, the video freezes every time i move away from it.

 

Today I had a struggle with the bluetooth. No matter what I did, it wouldn't connect to anything.. Removing and putting back the dongle didn't work. Stopping and starting the bluetooth service didn't also work. Rebooting also didn't work... ??? I had to shutdown the computer, remove the power, connecting it again and booting up. Now I have bluetooth. image

 

Uncompressing file

Today I had a rar file to uncompress. No success with the Raspberry PI OS .  Not fault of the Raspberry PI 400, but the underlying OS. I installed unrar-free but it wasn't unable to uncompress the file with the following error:

unrar 0.0.1  Copyright (C) 2004  Ben Asselstine, Jeroen Dekkers


Extracting from /home/pi/Downloads/compressed_file.rar


unknown archive type, only plain RAR 2.0 supported(normal and solid archives), SFX and Volumes are NOT supported!
All OK

 

If I check the file with the file command:

file compressed_file.rar 
compressed_file.rar: RAR archive data, v5

 

In my other computer, everything went without problems. Weird..

 

Well, this was all for today. This project is almost ending and I have lot of experiences to tell and talk about.
