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.

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.


There is no known solution or workaround for the problem.
