[edit] Description

Bluetooth device discovery on Symbian using the Qt Mobility API QBluetoothDeviceDiscoveryAgent may not report some local devices when both Bluetooth audio and wireless data connections are active.

[edit] How to reproduce

Connect a Bluetooth headset and start listening an internet radio over the wireless network.

Attempt to discover bluetooth devices with the API. No devices are discovered - and in the Qt Creator debug window you can see the following messages

[Qt Message] void QtMobility::BluetoothLinkManagerDeviceDiscoverer::RunL() 0 
[Qt Message] void QtMobility::BluetoothLinkManagerDeviceDiscoverer::RunL() -25

Where -25 means KErrHostResNoMoreResults.

[edit] Solution

There is no known solution or workaround for the problem.
