Bluetooth header file error on android

[Avtansh Sharma]

Hi,

I made a desktop application using Bluetooth. However I am unable to build it for android
I think the bluez is not present on Android.
Can anyone tell me how to install bluez on android

error: bluetooth/bluetooth.h: No such file or directory
#include <bluetooth/bluetooth.h>
^

Regards,

@Avtansh-Sharma It should actually work. Can you show the whole error log?
Are you using QtBluetooth or bluez directly?

I am using BLuez. It builds successfully as desktop application for linux but fails for android

@Avtansh-Sharma If you're using bluez then this isn't a Qt issue and you're asking in the wrong forum.
I don't know whether Android NDK contains bluez.

Hi,

If i use QTBluetooth then would I require the ndk to have bluetooth libraries or QT framework will take care of it.

@Avtansh-Sharma NDK contains everything Qt needs, at least it would be new to me that you would need to install something else.

I only used Bluetooth LE yet and it works great on Android and iOS

[Avtansh Sharma]

@jsulm Google discontinued Bluez and is currently using Droid Bluetooth since the kitkat version

[Avtansh Sharma]

@ekkescorner I cannot use Bluetooth Le due to hardware restrictions
