It does not store the number of records. Correct me, if I am wrong but isn't that known in this thread since April 2007?

Do you have a Schema or DTD for that? I just scribbled a few notes about an XML Format I want to convert my existing data to. Nothing is really settled and I have no Schema yet. Would not like to duplicate effort and be needlessly incompatible - would you share yours?

Sorry to raise a dead post.
But i have gotten food and exercise uploads working for the one touch ultra smart downloader from this post:

OneTouch UltraSmart Communication via RS232

Also i made some changes so that the libarary could be run in mono.

Digging deeper into this thread. I just purchased an Ultra2 after owning a bunch of Ultras for years. I have had a C program capable of talking to the Ultra's for a long time, and have been very happy, but the same app doesn't talk to the Ultra2. I've gotten the OneTouchLib going, but it can't communicate with the Ultra2. Is there something I'm missing here?

Yes: Ultra and Ultra2 have different communication protocolls.
A while ago the ultra2 commspecs were available at the lifescan HP. I donÄt know, if they still are... maybe it wasn't .com but .uk....

We created a web project to start a glucose tracking site, but the economics didn't work out so here is the code for the community licensed under GPLv2 or later. File attached contains code for reading Ultra2 and UltraSmart meters. For questions, please direct them to me via email.

[JasonJayhawk]

Beautiful code. I am extremely impressed! You might also consider putting it up on SourceForge!
Great use of the Boost library!

Hi,
I just joined today. My Ultra2 "Wakes up" using this, on the next line cut and paste?)
?
(...it is the ascii chars 17 and 68, which is translated from hex 11 0d)

[RogerD]

The LifeScan Ultra2 glucose meter
command DMF, (which sends the meter's
date and time from the meter's clock)
can be provided to the meter from the
pre-stored User Command in terminal
emulation program Uv/Term.

The following is an HEX string
110d0a444d46
translated to serial ascii chars
(note that it is then on two rows!) :


DMF

comprises [DC1][CR] acknowledgement command
and the LifeScan Ultra2 meter command "DMF" in caps.

Rather than sending it in a file
through the com port cable, a "prestored"
version of this may be assigned to a
"User Button" in Uv/Term thusly:

^mDMF^m

where "^m" is Uv/Term for "Control M", [cr/lf].
I open a capture file, choose a command button
for one of the commands -

DM?
DM@
DMF
DMP
DMSU?
DMST?

then close the capture file when meter is done.
While this works for me, YMMV.

Here is a sample capture file:

I'm trying to connect to a Lifescan Ultra Easy using HyperTerminal but haven't been able to get very far yet. Can anyone tell me what I need to do to 'wake it up' and display the 'PC' message on the display?

I did find this PDF on Lifescans website which details the Ultra Mini and Ultra Easy protocols. It also gives a C algorithm for generating the CRC

Also found this great easy to use Serial Port viewer:

Making progress.

Writing a program instead of using hyperterminal and can now get the meter to display 'PC', read Software Version, Serial Number and the count of how many BG readings are stored.

Just need to loop through and read all the individual BG readings now.

Hello,

Got the Ultra Easy all figured out and can now download my data, date time and BG.

I've been looking again at the Ultra Smart and have figured out the date (took a while to realise it uses minutes since Jan 1st 2000 instead of seconds since Jan 1st 1970)

But I'm struggling with the BG's on the Ultra Smart. I know it's the next two bytes after the date and I can get some of them to work out properly, but I had a few low readings that I can't get to calculate properly.

Can someone point me in the right direction?

Really wish Lifescan would release the specs for it like they do with all their other meters.

Thanks,

NiVZ
