[Interest] Bluetooth Low Energy on Windows: Options and feasabilty of implementing own backend

[Axel Jäger]

Hello,

I have created a Bluetooth Low Energy Peripheral and need to develop a
companion application on a windows desktop for it. I see that windows is
currently not in the list of supported plattforms of Qt’s Low Energy Module
and it looks like it will not be in Qt 5.5 according to this commit:

https://qt.gitorious.org/qt/qtconnectivity/commit/ffbb91da8e8f14d7d5ffa8bbea
ce3e6c42eb525b

 

I am using bluetooth modules from bluegiga and they also offer a bluetooth
stick with an own C API.

 

I see three options getting my task done and I am asking you which one you
think is most sensible one:

1) Implement my application using bluegiga’s API 

2) Implement a backend for Qt to use bluegiga’s hardware 

3) Implement a backend for Qt to use the Windows Bluetooth API from
WinRT/Windows 8.1

 

The options are ordered by estimated amount of work from least to most.
Surprisingly I get the same order when sorting by sustainability.

 

This means that actually option 3) is to be prefered. This brings me to a
couple of questions:

1)      Has anyone already looked into the Windows API and wants to make a
statement whether mapping Qt’s API to the Windows API is feasable?

2)      Is it actually possible to use WinRT on the Desktop as backend for
Qt?

3)      Is there an API or a plugin interface for Bluetooth LE backends in
Qt?

 

Can you comment on any of my points?

 

Best regards,

 

Axel
