Bluetooth with Windows ? (Bluetooth Low Energy)

NicoFrom13

Hello All,

My last post on this forum was very useful for me so i restart the experience :)

Is somebody able to give me a clue on a third party library that allows to scan Bluetooth Low Energy around ?
I mean i need it for Windows Platform.

I already tested with BluetoothApis.h from Microsoft SDK but this api is only able to detect Regular Bluetooth and not BLE (things that i don't understand because my windows 10 show me my BLE device in setting).

My research on this topic gives me 3 things :

Windows BluetoothApi (Already tested)
Bluesoleil (don't know how it works really and if i can use it with Mingw)
QZeroBluetooth (didn't really understand what it is)

So my question is simply, if somebody already created a soft using BLE could he gave me the library he used.

Sorry for my English that is might be poor, but this is not my main language.

Regards.

You are a monster ! that was this f**** command checkout.
I don't really understand how git works so that probably why i do weird things.

I need to learn more about git, i see it everywhere without knowing what it is :)

By the way i wish to thank you very very very much for your patience.
It Works, now i need to understand by my self why one of my ble device is not discovered :p but for that you can't help me.

Have a nice day and maybe see you soon on Qt Forum.

Hi,

One thing you can take a look at is the wip/win branch of the QtConnectivity module. It contains a work in progress Windows implementation.

Hope it helps

NicoFrom13

Aw thanks but i omit to mention that i already tried it, maybe i done wrong, but it doesn't work for me.

I cloned the git, then i opened multiple project such as Btscanner, Low energy scanner, ... with QtCreator 2.0, then i compil .... annnnd paff
compiled with QT 5.8 MingW 32b

"qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional."

SGaist

Maybe a silly question but did you rebuild the module ?

NicoFrom13

Aie, maybe the problem is here ...
How to do this rebuild on windows ?

While you answer me i'll will search

Edit :
By the way, i'm on Qt 5.8, free version (i don't know if it's usefull ...)

I copied the qtconnectivity branch to my "D:\Qt\5.8\Src\qtconnectivity" to replace it ( i made a backup just in case).
Now when i check the qmake.conf (with notepad) i see that the version is 5.8.1 instead of 5.8.0.

I guess that i need to rebuild in order to put the right lib file in my Mingw folder but i don't know how :)

SGaist

No need to copy anything.

Open a Qt command line

cd /some/place/
mkdir build_qtconnectivity
cd build_qtconnectivity
qmake /path/to/your/cloned/qtconnectivity
nmake << or jom
nmake install << **WARNING** will overwrite your currently installed qtconnectivity libraries

NicoFrom13

Many thanks for your reply.

Here is my result :
qmake -r D:\Qt\qtconnectivity

I Highlighted some problem if it is. i will test to make perl to be reconignez then i will edit this if any problem.

EDIT :
What a hell, i encountered many isue to install PERL on windows, then i had to download the portable version.
I modified my qtenv2.bat in order to add jom directory and my perl portable directory.

the build is under progress, i will keep you in touch of the result ....

EDIT :
Same error : qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.

I encoutered some error during the build 'file acces error used by another process' ....

I'm lost :p

SGaist

Did you restart from scratch once you had perl properly installed ?

And a silly question but, did you checkout the wip branch before building ?

@NicoFrom13 Hi, Were you able to use this work in progress qtconnectivity? Is it properly working ?
