The blob is just the binary version of the data that is already there in the other tables in the database. I spent some time looking into it as I wanted to add the sqlite import into my zeo viewer. I did build it in in my latest version, but there is a bit of a problem with getting the dates to line up. I don’t have a mobile system to be able to work out the timing, so I asked on the viewer thread for assistance, but no-one responed, so I assume there isn’t a demand for a mobile import.
I can tell you where the data is but obviously I cant tell you how to get the date right!
