| I've managed to break a lot of the protocol down, but its not as simple as only bytes. They use bit stuffing too, and the meanings of some of the bytes/bits change in relation to the value of other parts of the packet. Also, the CRC they use isn't a basic CRC, and all HR requests have to be signed with the proper CRC, or the meter will ignore them.
There is nowhere on the web that details the protocol, and Lifescan has stated in emails (see above, think its in this thread) it is proprietary information that they are not willing to share.
As for me, currently, I'm not at the point where I can share anything, as one, I don't want to 'publish' any information that very well may not be accurate, and two, I'm not sure if we're going to make the client libraries open source or not. There could be legal stuff being as it is a proprietary protocol, but I don't know for sure yet. You might try checking back in a couple months though.
In the meanwhile, check out the other areas of the forum! Do you have diabetes, if so, which type?
