| Aug 29, 2015 at 21:18 | comment | added | rev | Do you happen to have the binary that generates the checksum? (and more importantly, can you disassemble it?) | |
| Aug 29, 2015 at 20:42 | comment | added | Alexander Dimchenko | also here is the link to the excel file containing all samples grabbed, you can use filtering option to get more close samples - drive.google.com/file/d/0B6VO67TWi9UOSkt4VHJNQmtSTXc/… | |
| Aug 29, 2015 at 20:39 | comment | added | Alexander Dimchenko | this is an example of 2 samples with 2 different bits, one for the body, one for the crc | |

| Aug 29, 2015 at 20:20 | comment | added | Guntram Blohm | At least this doesn't seem to be a simple xor encoding of the bits. Do you have any examples that are closer to each other, for example, most of the payload identical, but 2 or 3 bits counting up from 0 to 3 resp. 7 ? | |
