Hi Steve,
QBluetoothTransferManager Class
http://doc.qt.io/qt-5/qbluetoothtransfermanager.html
Since Qt runs on both laptops and smartphones, I was not clear which target was
running Qt.
I use this to send firmware file updates to an embedded Bluetooth device

/// \brief Implements OBEX file transfer using Qt framework supporting

/// Qt 5.6 framework QBluetoothTransferManager supports platforms:

/// Android has QBluetooth support, however does *not* have
QBluetoothTransferManager support
/// - The Android implementation uses JNI to launch an Intent to Bluetooth
Share.
/// - While this appraoch works it confuses users:
/// 1. On updating a TK, the TSR app disappears.
/// 2. A file share window appears with list of *every* device that had
*ever* been paired.
/// 3. User must quickly select the correct TK_000X destination within
about 15 seconds.

Hi,
I hope i am right here. I want to send OBEX messages from my laptop to my
smartphone. The main goal is to get the contacts of my smartphone per PBAP
(phonebook access profile).
For this I created in QT a QBluetoothSocket which opens a RFCOMM connection to
my smartphone and connected it to the PBAP service of my smartphone.
Now i need to send a GET request and a message with headers and data. I know (I
hope so) which header and belonging data I need, but I do not know how to send
it to the socket.
The socket expects a const char *data parameter. What i need to send:
GET Request with Headers:
Header ID: Connection Id
Value: 1
Header ID: Name
Value: telecom/pb
Header ID: Type
Value: x-bt/vcard-listing
Can someone please help me how to create this data message and send it through
the socket to my smartphone?
I use wireshark to check the data, but all i get is a malformed OBEX package or
the laptop just sends an OBEX fragement, but no OBEX message.
Thank you.
