Discussions around DIY closed looping with #OpenAPS

Dave Acklam

@dcacklam

@garetis The Pi0 does not have the processing power to work with the HAT reliably. It tends to have issues with timeouts.
I had one working well enough with a plain radio board ('Slice of Radio' device), but trying to make it work with the hat resulted in something rather unstable...

IMHO the best Pi for a rig - if we had a radio/LCD-board designed for it - would be the CM4 or CM3

@garetis
Also, the easiest way to do offline looping with the G6, is to use xdrip-js & connect directly from your rig to the transmitter via bluetooth.

@chrisdex Contact ebay-seller 'all-of-cpu'.
He had a bunch of Medtronic 722s for sale at one time, and when I bought 2 (one as a backup) he offered to sell me the entire stock...
I didn't have the money for that, so I declined...

@garetis yes that's the code

Dave Acklam

@dcacklam

@jaybaron1
The Pi 0 has 1/4 the CPU cores of the Pi3 and they are less-capable cores as well.

@ecc1

@dcacklam there are some small carrier boards for CM4 with HAT-compatible headers, so one could use the Adafruit radio hat with it

one example: https://www.dfrobot.com/product-2196.html

@Foxy7 you could manually download your files from Ns command line and then upload to OH, but that’s a bit of work if you’ve not done it before. There’s a NS repo for the code behind the uploader tool if you want to check it out.

Can you file an issue in that repo and I can get someone to help take a look? Might be the heroku side of it (which I can’t remember if I have access to but won’t be able to check until I’m back on decent Wi-Fi mid week)

@ecc1
The hard part with the premade Pi4 boards is finding one with LiPo charge/power support.
I am becoming a bit convinced that - absent a new 4CM or 3CM based Explorer Hat - the best pi is the Pi3A (which is the same width as a Zero, the same CPU as the 'full size' Pi3, but has a greater height because it has the camera headers, HDMI and USB-A)

@dcacklam I can't reproduce that with go 1.15 from bullseye:

/tmp $ git clone https://github.com/ecc1/medtronic

Looks like your build is using an older version of code from the nightscout repo. I'd try removing your local copy of the Go source and retrying

Dave Acklam

@dcacklam

@ecc1
I am using the 'go' source that is installed by the oref0-install script.

Dave Acklam

@dcacklam

@ecc1

From oref0-setup.sh

    golangversion=1.12.5
    if go version | grep go${golangversion}.; then
        echo Go already installed
    else
        echo "Removing possible old go install..."
        rm -rf /usr/local/go/*
        echo "Installing Golang..."
        if uname -m | grep armv; then
            cd /tmp && wget -c https://storage.googleapis.com/golang/go${golangversion}.linux-armv6l.tar.gz && tar -C /usr/local -xzvf /tmp/go${golangversion}.linux-armv6l.tar.gz
        elif uname -m | grep i686; then
            cd /tmp && wget -c https://dl.google.com/go/go${golangversion}.linux-386.tar.gz && tar -C /usr/local -xzvf /tmp/go${golangversion}.linux-386.tar.gz
        fi
    fi

If you try running the oref0-setup on a clean SD card (pi) or Edison flash, you will get the above crash

Dave Acklam

@dcacklam

I updated the 'golangversion' to 1.15.13, and ran oref0-setup again.

Is it possible that the setup script is pulling the wrong go source from github?

Dave Acklam

@dcacklam

When I do a 'git clone' and a 'go build -v' I get the same thing you do...

But when I run the setup script it crashes and burns

The setup script is doing a ' go get -u -v -tags "$radiotags" github.com/ecc1/medtronic/... '

wherein radiotags = cc111x in my case

Eric

@ecc1

not sure the setup script is doing the right thing. it should clone and then build, not do a "go get" if there's no local source yet

Eric

@ecc1

sorry, my mistake. setup is pulling the master branch of the medtronic repo, which had lagged behind dev. I've updated them both now

Dave Acklam

@dcacklam

@ecc1
That fixes it.

Should rpi 4 works as a rig just like rpi 3?

tynbendad

@tynbendad

about the radio hack that attempts to guess your pump's serial number - has anyone tried to detect a hack in progress (e.g., from an explorer or explorer hat rig)?

is it feasible?

Eric

@ecc1

@tynbendad not sure what hack you mean, but it's trivial to snoop on pump comms in progress and extract the serial number, since it's not encrypted in any way. Impossible to detect, since it's receive-only

tynbendad

@tynbendad

Oh, ok that's worse than i thought. Thought they had to try every serial number, but maybe that's just for pumps that aren't using comms.

@jaybaron1

Thanks for sharing.

Dave Acklam

@dcacklam

@tzachi-dar rpi4 works as a rig but the battery circuitry on the explorer hat is too weak to power it.

@tzachi-dar So only really good for a desktop rig.

Use a pi3A+ or pizero for portable

tzachi-dar

@tzachi-dar

Thanks @dcacklam is using pi3A+ with a battery a reasonable thing to do? Seems like it's power usage is relatively high.

Dave Acklam

@dcacklam

@tzachi-dar just use a 6000mah battery

My backup rig isn't working at the moment so I'm unable to test a completely fresh install, but there appears to be issues with the current master branch of oref0 (0.7.0) and token-based NS authentication. I'm finally getting around to updating my rig with token auth instead of api_secret, but I've been troubleshooting an issue for the past several weeks where the rig does not include the token in several GET requests, resulting in an permissions error and prevents the rig from downloading BG data.

The current version of dev does not have this problem, and I finally found this commit which seems to describe the issue perfectly openaps/oref0@89a90b8 . Can anyone else confirm whether they are seeing this issue?

Dana Lewis

@danamlewis

I am not sure if that’s the only thing broken in master but you’re not the only one who needed to switch to dev recently and found it resolved the/an issue.

If we can get some volunteers to test some fresh installs and report back (here or in the open PR of dev to master), we could do a release (dev to master) and get master back to a working state.

How do I disable Autotune, but leave it to run each night on my rig?

I just want to manually observe recommendations

I keep dropping low and it keeps recommending more insulin. I can't figure out why.

I'm entering carbs.

Constantly getting negative IOB

old-square-eyes

@old-square-eyes

Do I just change "enable": " autotune ", to "enable": "",?

In prefs

Caleb Seekell

@jauntySerpent

@danamlewis I am happy to test as soon as I get my backup rig running.

Or do I delete the whole line
