Firmware 0.4.4 has been released (You MUST update!)


#1

Hi Guys,

We released firmware 0.4.4 today.
This release mainly increases the reliability by fixing bugs in the USB stack and by adding a watchdog timer that triggers a hardware reset if the controller stops responding for 60 seconds.

This firmware fixes a very important bug that could cause a complete freeze of the controller. Please update your controller as soon as possible!

You can view the full release notes here:

You can update by running our update script:

sudo python ~/brewpi-tools/updater.py

If you encounter problems during or after the update, please report them in this topic.
Updating your controller mid-brew is not recommended.

Cheers!

*** Done updating BrewPi! ***

#4

Oops, thanks. Fixed the instruction.


#5

To give other users some confidence. Update to 0.4.4 went well. Many thanks to Elco and his team!

update 0.4.4.txt (20.1 KB)


#6

Upgrade worked great!

Had to update /etc/apache2/apache2.conf and set the KeepAliveTimeout to 99 to keep Safari on iPad happy (remove the annoying Script not responding message).

Thanks @Elco!


#7

Thanks Espen,

Nice change!

don’t forget to restart apache after you edited apache2.conf

sudo service apache2 restart


#8

Updated with no issues, then added Espen’s apache edit… that’s been bugging the crap out of me!


#9

Updated with zero issues. The update didn’t disrupt any of my edited files (remote access for public / admin pages or my setup running Raspberry Pints and the BrewPi servers on the same Pi). Very nice…very happy. Also didn’t change any of my Advanced Settings that we custom setup for my conical FTSS/ Glycol chiller.


#10

Hi Elco,

Have updated to 0.4.4 appeared to go ok. The latest brew has been maintained perfectly.

However I seem to have a problem changing the beer set temp and or mode when using the web interface. I have in this instance tried to change the beer temp from 19 to 20, when “applying it” nothing changes on the web interface but the display of the brewpi does show the new temp.
Copy of the log when the change was applied.

Do you see anything I’m doing wrong, never experienced this problem before.

Cheers
Dave.

Have just noticed if I stop and start the script it does update the web interface?


#11

Thanks for that bug report! Took me a while to find the cause.

The bug was in the script:
Incoming serial data is read in a background thread. On incoming serial data, this background thread checks the buffer to find occurrences of \n to see if any complete lines are received and adds these to a queue.
The bug was that on each blob or incoming serial data, it only did this once. So if multiple lines were received in one blob, it would only process the first one and leave the rest in the buffer. It would only process the line it left when a new blob came in.

I think this went unnoticed with the previous versions of the firmware, because it was slower and it was unlikely that multiple lines were received in 0.01 seconds.

Anyway, it is fixed now. Please update your script. :slight_smile:


#12

OK… This is the part I’m having a little bit of trouble with being a brewer and not a programmer…“Please update your script”…

So, I go to the “fix for serial buffer being only processed 1 line at a time”’ and I see a file (or part of a file) “called”

backgroundserial.py

I assume this file resides somewhere on the Raspberry Pi in a BrewPi directory???

Looks like there are 8 additions and 4 deletions. Are these marked in the attached file? Or, will I need to go line by line and make my file identical? Or…Can I just cut and paste the entire file over the existing file?

Last question, I have not yet updated the firmware to 0.4.4, If I perform this update in the near future…probably tomorrow, will this issue already have been corrected on the update?

Thanks for your help.

Ric


#13

How do I update only the script? Run the update script?


#14

Thanks Elco, that’s sorted it!

For those who are as equally coding challenged…this it what I did, quote from an earlier post.

Updating your BrewPi (BrewPi Spark Only)
To update to the latest release, you can simply run our update script from the brewpi-tools repo.
If you followed or guide, this will be in ~/brewpi-tools/

So log into your brewpi via SSH (for example using putty16

And then run the following commands:

cd ~/brewpi-tools
sudo python updater.py
Quick tip: use TAB to auto-complete file names. You’ll make less errors.

The updater will update the script, web interface and dependencies. It will then ask to check for updates for your controller

That’s it. If you are up-to-date.

Good luck

Dave.


#15

Yes, running our updater is the safest way.

Another option for advanced users is to go to the directory:
cd /home/brewpi-script
And do a git pull
git pull


#16

If you run our updater, this fix is already included.


#17

YES!!! Got it! Even we python/raspian/RPi challenged people can do this!!!

Thanks to all.

Ric


#18

I assume that this does not apply if you have the arduino stack?


#19

Correct, the current code base is not compatible with Arduino because it doesn’t fit the platform anymore.


#21

I just ran the updater today and after a small log-in problem (user problem, not system) everything seemed to go OK. After the update I changed my beer, and switched to fridge constant temp. But after 20 minutes it does not seem to be heating. Is this a glitch? What other information should I send?

Prettige Kerstfeest
