Maybe you should just do bluetooth turn off/on programmaticaly from your app, before using of an BLE.

not working :/ if i compile bluez5, qt5 dont recognize bluez. qmake says for the qtconnectivity modul : "Checking for bluez... no" "Checking for bluez_le... no" If i installed bluez 4.99 over apt-get bluez is recognised, only bluez_le not. do i have to change other settings after compile and install bluez5? EDIT: i have upgraded to jessie, no its working. Jessie uses bluez 5.23. maybe it's also working if bluez5 is used on wheezy, don't know.

Hi and welcome to devnet, If possible, you should upgrade to 5.5, IIRC, there's been a lot of work done in the bluetooth module for it.

Nop, sorry, I don't

Release Candidate packages are in preparation, you can already try the beta

Thx, i will give it a try

@nedo99 There is starting with Qt 5.5, see the new feature list

I installed the Ubuntu 14.04, but does not turn on bluetooth. I installed the OpenSUSE and I was able to run btchat. http://doc.qt.digia.com/qtmobility/btchat.html Successfully connected to U30GT-H and produced messaging. But between android devices nothing works. And the example of "Bluetooth QML Ping Pong example" is also not works. Sorry for my english.

Hi and welcome to devnet, For the bluetooth side Qt 5.5 is more likely what you are looking for. As for developing on both mobile platform, currently it's indeed mandatory to have an OS X system. Virtualbox seems to only support Mac OS X Server (Leopard, Snow Leopard). At least it's what they lists. Also note that to be able to test your application on your iPhone/Pad etc. as well as submit it to the App Store, you need to enroll in the iOS developer program Hope it helps
