It looks scrambled, and haven't had the time to decipher what might

Checked your btle_ostc4.txt and see that you are connecting to the
wrong service. You need to connect to
the service starting with 0000fefb (which is the Stollmann Terminal IO
thingy). And yes, the
current master selects the wrong service, so you have to adapt the
code for that. In addition, you need
to select the proper characteristic to receive notifications. I have
added a patch from Linus (from yesterday)
the takes care of selecting the proper characteristic, and one of mine
to select the proper service (and
mine contains also a lot of debug crap, so be careful if you want to
apply this).
And the bad news is .... with all this I still cannot get downloaded
data from my OSTC3 (but it
selects download mode correctly).
Ok, reading the Stollmann TIO doc carefully, it is clear that we do not
correctly follow the mandatory initialization
of the connection to the Terminal IO. So my guess at this point is, that
that is the main reason things do not work. I am
working on an improved implementation of the TIO handling, and taking
care not to break other BLE stuff. Hopefully
later today an update on this.
