[Flatpak] Bluetooth client mode doesn't work

[halfrafu]

Hello, thanks for the great serial port utility.

I've tried connecting to my HC-06 bluetooth module and while it's getting discovered properly I can't connect. I'm getting a "Cannot establish the connection. Service cannot be found." error.

In the logs I'm getting this:

qt.bluetooth.bluez: SDP search failed for "<HC-06 adapter's MAC>"
Connection::onErrorOccurred()
BT Socket Error: QBluetoothSocket::ServiceNotFoundError "Service cannot be found"
State: QBluetoothSocket::ServiceLookupState
Connection::onDisconnected()
IODevice Disconnected
Connection::onDisconnected()
Connection::onDisconnected()
QCoreApplication::postEvent: Unexpected null receiver
qt.bluetooth.bluez: Cannot find sdpscanner: ""

So it seems to me that sdpscanner command is missing and in fact it's not available in the flatpak container. I've tried installing sdpscanner command on my host system but it didn't help. I think it's necessary to bundle sdpscanner together with the app.
