dxtool is a very minimalistic implementation of the DistoX communications protocol, as described in "DistoX Advanced Information" (2010/12/12). It runs as a Linux command line application. Originally, the utility was created to re-download already downloaded measurements. Since the DistoX uses a circular buffer to store measurements, it is possible to recover last 4095 measurements, even if they have already been downloaded to PDA. Another possible use of the software is QUICKLY downloading LOTS of unneccessary measurements from a DistoX that has been used with a paper notebook.
Download dxtool v 0.1 from 2013-09-29.
