Decoding carelink

For an intro, see insulaudit. We are hoping to help diabetics independently reproduce therapeutic audits of their Medtronic insulin pumps. This experimental software will download pump settings, and the entire log of historical data.

Status

We can decode many of the opcodes that store configuration settings. We can also download all pages of history from the ReadHistoryData command, which contains the log of all actions the pump has taken on your behalf:

glucose readings
all bolus dosings, all usage of bolus wizard
unabsorbed insulin
alarms, etc...
current settings
query pump status: normal, suspended, bolusing ./bin/mm-set-suspend.py
set/edit/query temporary basal rates ./bin/mm-temp-basals.py
press any button on the keypad, using ./bin/mm-press-key.py
Investigate how any command works, make new commands, download any command ./bin/mm-send-comm.py
Bolus ./bin/mm-bolus.py

Install first run

This only needs to be done once:

From pypi

$ easy_install decocare
# or
$ pip install decocare

From source

git clone https://github.com/bewest/decoding-carelink.git
cd decoding-carelink
sudo python ez_setup.py # only if you rarely use python
sudo python setup.py develop

Contribute your logs

Fork the repo, create a new branch, send the results back to your branch. There will be a green "create pull request button." Putting your logs back on github will allow more people to assist in decoding results.

git checkout -b myname/init # replace <myname> with your name
# all done

Find/Create serial device in the OS

Congratulations, now you are ready for the demo: Plug in the carelink usb stick, and run this:

dmesg | grep ttyUSB # notice the new ttyUSB$x
sudo ./insert.sh

You are all done with setup. Here's how to test just the usb stick, then we'll run the full suite of experiments.

on MAC the PORT is called /dev/tty.serial or something.
on windows the PORT is called COM1 or something
on Linux the PORT is called /dev/ttyUSBx or something

Get your logs

python decocare/stick.py /dev/ttyUSB0 # on windows this is called COM1
# should get a bunch of output, notably some counters called INTERFACE STATS

export SERIAL=208850
# Turn RF POWER ON for 10 minutes
# You have ten minutes to talk with the pump.
# should say hello, and print serial number
mm-send-comm.py --init sleep 0
# print serial number
mm-send-comm.py sleep 0
# get logs
mm-latest.py

Fantastic. Send me your results! The following process uses git to store your recent results. You can email me a bundle, or simply push your branch back to your fork on github.

Do this every time, after you run some experiments:

git commit -avm 'for @bewest, these are @<my-name> results'

Set up for sending me results.

# email me your results like this:
git bundle create myname-expr.bundle master..myname/init
# you can send me myname-expr.bundle in an email

Even better, fork the repo and setup to for easy.

# add your fork like this:
git remote rename origin author
git remote add origin [email protected]:<my-user-name>/decoding-carelink.git
git push -u origin myname/init

Now you can do this easily:

./status-quo.sh /dev/ttyUSB0 <pump-serial> # use your pump's serial number
git commit -avm 'for @bewest, these are @<my-name> results'
git push -u origin myname/init

Repeat. The easiest way to see what happened is to look at explain.log, and use git diff and git show. Pushing to github as shown above will allow everyone to discuss our analysis together.

There are several log files created for each experiment.

Demo

If you don't want to use your own equipment, I've made some of my test equipment available. Talk to my test insulin pump over the internet.

Requires socat and python 2.7. The script ./bin/socat_run_app.sh will connect to my server, bewest.io:8080 where my test insulin pump, serial 208850 is waiting to talk to you.

Here's an example using my scripts:

$ git checkout -b tester # create a new branch with just your stuff, please
$ . ./bin/common # import some handy run_* functions
$ ./bin/socat_run_app.sh & # get my test insulin pump from bewest.io:8080
$ ls carelink.ttyUSB0  # creates this thing
carelink.ttyUSB0
$ ./status-quo.sh ./carelink.ttyUSB0
[...]
$ PORT=./carelink.ttyUSB0 SERIAL=208850 run_download 
[...]

Try figuring out the dosing commands. Is it possible to rewind the pump? Is it possible to enter new profiles and schedules?

Future work

collect more data
finish analyzing pages of insulin pump history
https://github.com/bewest/decoding-carelink/tree/rewriting/analysis/pages ** analyze insulin pump bolus records ** help analyze prime events ** help analyze pump midnight events

Once we can decode historical logs, we'll clean up and merge back into insulaudit

Help needed

Documentation of protocol, decoders, etc...

# fork the repo on github
# clone the repo
$ git clone [email protected]/<yourname>/decoding-carelink.git
$ cd decoding-carelink
$ git checkout -b <yourname>
$ ./insert.sh # will ask for sudo to configure usbserial for the stick
# ./status-quo.sh [[<path>|/dev/ttyUSB0>] [<serial>|208850]] eg:
$ ./status-quo.sh /dev/ttyUSB0 208850
$ git commit -avm "here is my data <yourname>"
$ git push -u origin <yourname>

Thanks! If you can include CSV export from carelink, it would be helpful.

Decoding

We know how to decode time and as a result we can find and parse most records now.

And lining this up with the Carelink CSV exports reveals the nature of the contents for further analysis.

Once we can decode all records, it should be useful for diabetics, to get basic reports, more or less on par with the vendor's solution. We'll use it to collect diabetes data (https://github.com/bewest/decoding-carelink/tree/rewriting/analysis/pages) over the internet, allowing anyone to independently audit their therapy, and then send the data to their preferred auditing software.

`status-quo.sh`

status-quo.sh </dev/ttyUSB0> <SERIAL> runs several experiments, described below. Each experiment is saved in the ./logs directory, which is tracked by git.

`. bin/common`

Source a bunch of helper functions, notably:

`run_stick`_

Runs python decocare/stick.py /dev/ttyUSB0 and saves results in logs/stick.log. When run by status-quo.sh, it creates ./logs/baseline.stick.log before continuing. At end of experiments, it records ./logs/postmortem.stick.log

`run_session`_

Runs python decocare/session.py /dev/ttyUSB0 <SERIAL> and saves results in logs/session.log.

`run_commands`_

Runs python decocare/commands.py /dev/ttyUSB0 <SERIAL> and saves results in logs/commands.log.

`run_download`_

Runs python decocare/download.py /dev/ttyUSB0 <SERIAL> and saves results in logs/download.log.

The download script is configured to save each page of historical data as a raw binary blob in the ./logs/ subdirectory like this: ./logs/ReadHistoryData-page-$x.data.

This script can take several minutes to run; it attempts to download all pages of data available.

quick overview:

status-quo.sh also tries to summarize what happened, saving a quick explanation of what happened in logs/explain.log. The entire output is saved in ./status-quo.log.

`run_regress`

After . bin/common, export SERIAL=511888 with your serial number.

Runs python list_history.py on each binary file found in logs/, saves results in ./analysis/<SERIAL>/....

This is what I use to render the markdown files in analysis. Often, the diffs between runs help test theories.

`list_history.py`

list_history.py [--larger] ./logs/ReadHistory....page-0.data List/decode a page of history as markdown.

`list_opcodes.py`

list_opcodes.py List records found in binary data by looking for opcodes, and a regular data structure associated with that length. Includes at least one variable stop length strength.

`list_dates.py`

List records found in binary data by looking for dates.

usblyzer_filter.sh

# usblyzer_filter.sh was used to filter the raw usblyzer csv export into
# something a bit more manageable.
