I have tried the following:
1) mobile on desktop, reading from the libdc simulator => working (as 
expected),
2) mobile on desktop,reading from OSTC3 over BT. For this, I hardcoded 
the BT address of my OSTC, and set the BT mode to true (obviously). The 
OSTC goes correctly in download mode, and stays there for multiple 
minutes. The console finally shows "Finishing the thread dives 
downloaded 125". So, the next breakthrough today :-) The first download 
over BT from a real dive computer :-) And most impressive, without 
changing any of the code from Tomaz. Obviously, there is something 
needed: a progress (toast) style thingy, or any other indication that it 
is downloading. Further, I was downloading in my normal logbook, so I 
did not expect any dives downloaded that were already downloaded 
(without looking to any code at this point).
3) mobile on mobile ... ok, this is not working yet. I verified that 
pairing is ok, and I can trigger a download over my mobile (using 
terminal input), so raw serial traffic. So the two devices can 
communicate. It seems that subsurface mobile is not attempting any 
communication.
