Support for settings extraction on Cresta alike watch

[mlt]

The binary data saved are just whatever was requested and received from the watch. Sent commands are not stored. That is if no READ_SETTINGS was issued, then there would be no settings stored in a binary dump. Moreover if there was an incorrect number of bytes read, it would be stored that way in a dump. So it was mostly useful for me in initial stages. One idea would be to keep reading 1 byte at a time and flushing output indefinite number of times upon issuing READ_SETTINGS, then disconnecting the watch. Another option if you have an access to Windows machine, is to use proxy DLL (or maybe just Wireshark with USB packet capture) and record communication for original software.
