The "still got some trouble with specific values" is a bit more trouble than I thought. When waiting for data from the glucometer I used a timeout of about 0.1-0.2 seconds. This is (on my hardware) enough for waiting to see if it answers, as long as there is data saved on the meter. When there is no data, the reply takes about 0.75 seconds. So I found out only a litte more than 100 correct crcs, all the other values are worthless. But I inserted fresh batteries and started the 'tryallcrcs'-programm on my server, let's see when it will be finished ^^.
But assuming it will finish one day  then I have a legal question:
may i publish these crc codes together with my source code under any licence (e.g. GPL)? I didn't obtain any information from Lifescan, thus didn't subscribe any contract. I just sniffed a bit data and found the checksums by trying out all the posibilities (well... I'm on it). If there is no concern about legal issues, i'd love to write and publish a program, cause I just can't find software, that I can use with my glucometer AND pump that satisfies me. But writing it just for me is boring...
Thanks (and by the way sorry for my "germish english"  ) |
Yes, if you did not use any of the Lifescan specifications or copyrighted code, you are allowed to publish it. This is called clean room reverse-engineering, as Jay Levitt mentioned above.
By the way, I am writing a Linux Diabetes Management program in Mono/GTK#. I'm not finished, but when I have something that is at least semi-useful I will publish it.
