To set up a Symbian device for debugging:
Connect the device to a computer. If you are using an S60 5th Edition or S60 3rd Edition FP2 SDK, the supported connection type is WLAN. From Symbian^3 onwards, the supported connection types are Bluetooth, USB, and WLAN. For more information about establishing a connection, see the SDK documentation.
Install the EcmtAgent onto the device.
Launch the EcmtAgent and select the appropriate connection type from Options > Settings > Bearer. Keep the EcmtAgent running on the device throughout the debugging session.
Figure: Changing to a USB connection in the EcmtAgent
The Symbian device is ready for ODD. You can now set up the Device Connectivity Tool.
