As far as I've know, there is no difference in the communication, if its
done over bluetooth or ftdi-usb-serial. In subsurface case its all
transparent. Also, as far as i've know and from previous discussions
with Matthias and Co, hwOS Tec and hwOS Sport should just behave the
same way when trying to configure them, and hwOS Sport just ignores the
bits it doesn't "understand".

The odd child in the bunch is the OSTC4. Its a slightly different
protocol, with config variables meaning slightly different things.

We should probably add the OSTC 2 TR to. There are quite a few config
variables thats new and should to be added to.

I haven't had the time to keep up with all the new interesting things
thats landed in hwos lately.

Correct. There is the exact same code on our (OSTC) side.


with Matthias and Co, hwOS Tec and hwOS Sport should just behave the
same way when trying to configure them, and hwOS Sport just ignores the

Also correct. We try to make these two branches as compatible as 
possible. All settings not included in the hwOS Sport are ignored from 
the hwOS Sport.

The OSTC4 will be fully open-source very soon, as well (We're just 
cleaning up the code so it's a bit more understandable). So I hope to 
make the OSTC4 configuration-wise as compatible as possible then. 
Firmware update is and will be different, though.



We should probably add the OSTC 2 TR to. There are quite a few config
variables thats new and should to be added to.


Beside the firmware update (the OSTC 2 TR has a software-defined radio 
receiver which can be updated additionally to the normal firmware) the 
OSTC 2 TR is either an hwOS TEC or hwOS Sport OSTC. Nothing special for 
you to do.


regards,
Matthias

Subsurface configure DC feature and OSTC Plus

[Stefan Fuchs]

Hallo Matthias,

could you please maybe answer the Subsurface and OSTC Plus related
question here:

https://github.com/Subsurface-divelog/subsurface/pull/1147

And maybe even quickly review the small change?

Thanks!


Viele Grüße
Stefan
