So, thanks to me giving a competent person (who also doesn't own any Windows or Android devices) a couple of distoX's that needed calibration, the software situation just improved. Stuart Bennett wrote a python script to do the device detection, calib toggling, data dumping and calib coefficient upload/dpownload, and another to convert csv to the format that topolinux calibration code expects. Combining these bits with a sufficiently-recent (>=0.2) pybluez, I managed to dicover device, set up connection, pair, set calibration mode, do a calibration, download the data, process it with topolinux, and upload the resulting coefficients. i.e. a full linux-based calibration (for a distoX1 only so far), for the first time in about 6 years. Yay! So thanks to Stuart for sorting that. The script is handy in that it deals with discovery, pairing and rfcomm setup painlessly. At the moment this only works with python3 and distoX1, But Stuart plans to use the topodroid codebase to work out the differences for the X2 protocol (unless anyone has a doc for this already, or Marco can tell him). Then the code really needs to be made python2 compatible, because Debian fucked-up and accidentlaly uploaded pyblues 0.18 source as pybluez 0.22, so the forthcoming stable will only have bluetooth support for python2, so this will remain the situation for the next 2 years. This is just the byte-string construction, which is easy and native in python3, but a bit of a pain in python2. Once this is sorted, I plan to package this (i.e these scripts and the calib utilities from topolinux codebase) as distoxtools or something similar so that linux people can easily calibrate/download.
