#Running multiple toit containers with a Global clock that can put ESP32 in deep sleep mode

Thread channel in help

Hi,
I would like to ask you how can I run multiple different Toit containers and also have this possibility to put my ESP in deep sleep mode. I want the device wakes up every 20 mins (e.g.) and process different containers and then go to deep sleep mode again. But now i can just have one container with different functions which also has the deep sleep. thanks in advance for your support

The easiest would be to use Artemis (https://docs.toit.io/getstarted/fleet). It does this for you.
Otherwise there are a few options:
- Modify Jaguar so it goes to deep sleep when all containers are done. Jaguar is surprisingly small so that isn't as hard as it sounds. https://github.com/toitlang/jaguar/blob/main/src/jaguar.toit
I feel like the biggest challenge would be to install the modified Jaguar. If you have some idea of how to do it it's not hard, but otherwise could be challenging. If you go this route let us know so we can direct you a bit.
- Use services to communicate between the individual applications. When an app is done it simply sends a message to the shutdown service. That one then goes to deep sleep when everything is done. Still requires the individual applications to be shutdown aware, though.
- Probably others.

Unless you need to use open-source, I would try Artemis first, though.
If you like tinkering with other programs, then modifying Jaguar could also be fun.

Thanks a lot Florian, one question, in Artemis, I also can have multiple containers?(edited)

floitsch 06/07/2023 08:42 AM

yes.

floitsch 06/07/2023 08:43 AM

You create a pod-specification that contains all the containers you want.
You then say at which interval they should run.
Whenever no program needs to run Artemis goes to deep sleep until the next program should run.

This example has two containers in it.
The "hello" and "solar" one.

floitsch 06/07/2023 08:45 AM

If you need your device to go to deep-sleep you also need to change the "max-offline".
If it is 0s, the device will stay awake and continiously request updates from the server.

Shadi 06/07/2023 08:45 AM

this seems the Artemis is like as docker-compose?

floitsch 06/07/2023 08:45 AM

there are some ideas from docker

floitsch 06/07/2023 08:45 AM

It's more descriptive.

floitsch 06/07/2023 08:46 AM

Docker compose is a bit more imperative. You can write commands one after the other.
The pod specification is a description of what should be installed. Things aren't executed in any order.

floitsch 06/07/2023 08:46 AM

I think you had a look at Toit v1 at some time. Artemis is the successor to it.

Shadi 06/07/2023 08:49 AM

perfect, Now I completely understand what is going on, Thanks a lot

Shadi 06/07/2023 08:57 AM

I am trying to install Artemis on mac, but I get error: % /Volumes/artemis/artemis ; exit;
Error: Missing subcommand.

floitsch 06/07/2023 08:57 AM

That's a good start.

floitsch 06/07/2023 08:57 AM

artemis is a command line application.

floitsch 06/07/2023 08:59 AM

You can follow the "getting started" at https://docs.toit.io/getstarted/fleet

But fundamentally you now need to:
- signup
- create an organization
- initialize a fleet directory
- modify the pod specification
- create a pod and install it

Shadi 06/07/2023 09:07 AM

Actually I followed these steps to sign up and I get the error: zsh: command not found: artemis

Shadi 06/07/2023 09:07 AM

I believed I did not install artemis in mac correctly

floitsch 06/07/2023 09:37 AM

You can always use a relative or absolute path to it.

floitsch 06/07/2023 09:38 AM

If you downloaded it you can add it to your path by writing export PATH=$PATH:$PWD (assuming you are in the folder that contains artemis).

floitsch 06/07/2023 09:38 AM

After that you can just write artemis and it will find it. At least in the terminal where you wrote export ....

Shadi 06/07/2023 09:40 AM

thanks I will try this

Shadi 06/07/2023 09:49 AM

One more question, I would kindly ask if you update the Jaguar? because two weeks ago when I try to measure energy consumption of my setup while using toit/jaguar was less than today.

floitsch 06/07/2023 09:49 AM

So Jaguar was using less energy two weeks ago than it is today?

floitsch 06/07/2023 09:50 AM

We do update Jaguar regularly, but we don't do anything behind your back.

Shadi 06/07/2023 09:52 AM

ok, thanks a lot

floitsch 06/07/2023 09:55 AM

Usually the biggest energy consumption comes from connecting to WiFi. So maybe it has a harder time connecting to it.

floitsch 06/07/2023 09:57 AM

Artemis is generally better for battery operated devices, so I would redo your measurements with it.

floitsch

If you downloaded it you can add it to your path by writing export PATH=$PATH:$PWD (assuming you are in the folder that contains artemis).

Shadi 06/07/2023 10:02 AM

Excuse me for this basic question, should I export the path of artemis.exe ?

floitsch 06/07/2023 10:02 AM

After adding the directory of the artemis executable to your PATH you should be able to just write artemis and the shell will find it.

floitsch 06/07/2023 10:03 AM

If you export it then sub programs can also see it.

floitsch 06/07/2023 10:03 AM

Typically you export it to make things easier.

floitsch 06/07/2023 10:03 AM

In both cases it's just a temporary thing, as a new shell would not have the artemis-folder in the PATH.

floitsch 06/07/2023 10:03 AM

You can make it more permanent by changing your .zshrc

floitsch 06/07/2023 10:04 AM

(I'm assuming you are running zsh since you mentioned macOS, and that's the default there)

Shadi 06/07/2023 10:07 AM

,I export the path of my executable artemis but still i get the error : he error: zsh: command not found: Artemis. , I click on artemis.dmg I get the warning: “artemis” is a Unix app downloaded from the internet. Are you sure you want to open it?

floitsch 06/07/2023 10:09 AM

The 'dmg' is just a disk image that contains the artemis executable.

floitsch 06/07/2023 10:09 AM

You should be able to drag&drop the artemis file out of the dmg and store it somewhere easier to find.

floitsch 06/07/2023 10:09 AM

For example, you could create a local/bin directory in your home and copy it there.

floitsch 06/07/2023 10:10 AM

then you would have export PATH=$PATH:$HOME/local/bin

floitsch 06/07/2023 10:11 AM

Apparently you should just drap the dmg into your "applications" folder.

floitsch 06/07/2023 10:11 AM

(just learned that).

floitsch 06/07/2023 10:14 AM

(but we are still investigating. We are just very used to modifying the PATH so we aren't too familiar with the typical macos flow).

floitsch 06/07/2023 10:17 AM

After looking more, it seems like applications isn't actually a good place for it. So putting it into local/bin in your home is probably the best.

floitsch 06/07/2023 10:18 AM

We will see if we can get a brew setup working. That would make things easier to install.

Shadi 06/07/2023 11:06 AM

ok thanks a lot I will try thi sapproach

Shadi 06/07/2023 11:56 AM

I would like to ask you a question as I could not install artemis on mac. I tried to install on linux and I add the path to Artemis to my path. but after running this command "artemis auth login" I get thi serror: GLBC_2.29 not found (required by artemis)it(edited)

floitsch 06/07/2023 11:58 AM

usually that means that your Linux is not up to date.

floitsch 06/07/2023 11:59 AM

It could be that we are compiling on a Linux that is too recent.

floitsch 06/07/2023 11:59 AM

Let me check what version we require.

floitsch 06/07/2023 11:59 AM

We are using the latest Ubuntu.

floitsch 06/07/2023 11:59 AM

I will change it to something older.

floitsch 06/07/2023 12:00 PM

Give me a few minutes and I will upload you an Artemis version that hopefully works with your system.

floitsch 06/07/2023 12:06 PM

After a second look, it looks like we are already using Ubuntu 20.04 to build.
Is your system older than that?

floitsch 06/07/2023 12:10 PM

If you want to try again on macos, here are the commands I would use:

cd /tmp
curl -L -O https://github.com/toitware/artemis-releases/releases/download/v0.6.2/artemis-macos.zip
unzip artemis-macos.zip
chmod +x artemis
mkdir -p $HOME/local/bin
mv artemis $HOME/local/bin
export PATH=$PATH:$HOME/local/bin
cd $HOME
artemis --version

floitsch 06/07/2023 12:11 PM

If you are running the zsh. (You can check by running ps -p $$) you can change the PATH for future sessions by running the following command:

echo "PATH=$PATH:$HOME/local/bin" >> $HOME/.zshrc

floitsch 06/07/2023 12:14 PM

You can use chat.openai.com to get a pretty decent description of what each of these commands is doing.

floitsch 06/07/2023 12:15 PM

I asked chat.openai.com of whether these commands should work on macos, and it claims that unzip might not be available directly or not have all the necessary features.
If you have difficulties with unzip you can either try to install a better version with brew install unzip (assuming you have brew installed), or simply unzip the archive by hand.(edited)

floitsch

If you want to try again on macos, here are the commands I would use: ``` cd /tmp curl -L -O https://github.com/toitware/artemis-releases/releases/download/v0.6.2/artemis-macos.zip...

Shadi 06/07/2023 01:05 PM

Shadi 06/07/2023 01:06 PM

Thanks for the hint, further I will first ask chat.openai.com.

floitsch 06/07/2023 01:07 PM

It's not perfect (and often hallucinates/lies), but for these kind of things it's a good help.

bmentink 06/09/2023 02:18 AM

The method that works for me, is to open the. dmg file, then in a terminal, type: cp /Volumes/artemis/artemis /Applications(edited)
