To use any version of the on-device debug agent on a target device it must be installed. We highly recommend using the On-Device Connections dialog to help connect and verify that the latest version of TRK (3.2.6+) is installed on the device, especially to support plug-and-play (PnP) connections.
Refer to the Bluetooth Connection Setup page for more information on using Bluetooth or the USB Connection Setup page if using USB.
