| | | OneTouch UltraSmart Communication via RS232
Fellow computer nerds,
Do any of you know how to translate the ouput of a Onetouch US into a readable text? Here is a sample (thank you Kevin!):
<DLE><STX><SOH><CAN><RS>3r0<NUL><SOH><NUL><RS><D LE><ETX>s
<DLE><STX>HR<SOH><DLE><ETX><DC3>
<DLE><STX><SOH><FS>3<DLE><DLE><NUL><SOH><NUL>C <DLE><ETX>z
<DLE><STX>HR<SOH><DLE><ETX>=
<DLE><STX><SOH>u<ESC>3`<NUL><SOH><NUL>{<DLE><ET X>M
<DLE><STX>HR<SOH><DLE><ETX>'
<DLE><STX><SOH>%<ESC>3{`<NUL><SOH><NUL>Z<DLE><ET X>)
<DLE><STX>HR<SOH><DLE><ETX>a
I know what this is, I just don't know how to translate it into meaningful data. Any help would be much appreciated.

| | | FYI....the above data from the UltraSmart is ONLY BG readings and datestamp. I don't use any advanced features, so there is nothing on the carb, insulin, etc. data that can be stored as well.
Brion...I hate to say this, but it may be easier to find a way to crack the archive files open from the Lifescan software and import the data that way. But then of course you have to figure out what password LS uses, lol.

| | | Then prepare to be impressed! <g> I'm not divulging the password on the open forum, however. I also don't have it listed on my current PC--it's most likely on my previous PC sitting in the attic...along with a few other retired PC's. If I had all the money I've spent of computer stuff since '85, I'd be a rich man! |

BTW, with my leg injury I'll not be rummaging around in the attic for quite some time to recover the password from my old PC. |

<G> Sorry to hear about you being w/o a girlfriend! That's MUCH worse of a predicament than an injured leg. |

| | Brian,
Are you using a serial port sniffer to view the RS232 traffic? While there's a pattern in the data, I've seen the same pattern from an airplaine traffic avoidance system, only to discover that I was reading at the incorrect parity or bit length (7 vs. 8 bits) -- after correcting it, the pattern went away, and a new pattern emerged that was in good human text.
If you're "sniffing" and the Lifescan software is simultaneously receiving the data with no problems, then that certainly is a weird data format. Otherwise, the "mean" engineers have decided to transmit the data in a obfusicated binary method. The only way to "crack" that is to get a data transfer performed on a meter, then add one value, and transfer again, and then "diff" the two, and try to extract a pattern.
The OneTouch Ultra transfer protocol, I recall, was in text, with a checksum value added at the end of each line.
Do you have the RS-232 communications specification document for the Ultra meter? If not, let me know, and I'll get my old computer out and booted and will send you it... It's been two years since I've looked at it, so I don't know how detailed it was (it was a very short document, and you probably already have it).
I sort of assumed they would have kept the comm spec the same for the UltraSmart, only with the addition of the insulin/med/exercise/(and so on) data. *grumble* 
Think Lifescan would be kind enough to reveal  their format like they did for the Ultra?  |

If so, I've seen some brute-force password cracking programs "out there" (good for the people who forget their database passwords). I'm sure we could get in to one if nobody remembers the password or can't find it in cleartext in the executable.  |

I think I cracked it in about 10 seconds... |
