Tested the -300 code. All self build, and Qt 5.9.0 from the Arch Linux
repos, so no specific update to 5.9.1.
1) desktop version: downloads OSTC3 over BT correctly.
2) mobile-on-desktop: downloads OSTC3 over BT correctly.
3) and it getting boring :-). True mobile on Android 7.1.2: downloads
OSTC3 over BT correctly.
In addition, I tried the LE: quirk on desktop, to see how far I would
get for OSTC3 over BLE. Below, the logging from the console.

So, there is some communication, and with my very very limited knowledge
on BLE, it seems that the correct service is detected (Found service
"{53544d54-4552-494f-5345-525631303030}" and things finally seem to fail
with something encryption related? If needed, i can produce screendumps
from Nordic to see what BLE things are visible on the OSTC3, but I
suspect that most of the required data is in the log above.
Obviously, OSTC3 over BLE is not the most important capability, as it is
only needed for iOs users and Android users are perfectly served with
only BT, but it would still be nice to get it working.
