## Installing On-device Debug Agents using Bluetooth

Use Bluetooth to install the on-device debug agent, either Application TRK or System TRK, as a SISX file, to enable on-target debugging. The installation location of the on-device debug agent will vary based on the phone. Application TRK is usable on both consumer and RnD versions of the device. System TRK is only usable on RnD devices.

On some phones it will be the Installed folder, on others it may be in My Own folder. Refer to the documentation that came with the phone to learn where installed programs are stored.

NOTE The following example shows how to install the SISX file from a PC running Windows XP SP2 using an internal Bluetooth device. The actions to install the SISX file may be different on your version of Windows. Refer to the OS documentation for information on transferring a file via a Bluetooth connection.
