@Jim_Rockford: Are you scanning or tuning? If you are tuning, you need the xdf file. If you are scanning/datalogging, you will want an adx file. Because you state Bluetooth adapter, I'm assuming you want to scan. Tuning usually request an Ostrich connected via USB.

Based on your vehicle in your signature, you probably want the A217 adx file off the tunerpro.net website. (I'm sure the same file is on gearhead-efi too)

Place the adx file in your /ALDLDroid/adx/ folder of your phone. Then go into ALDLDroid settings, select 'Datastream file'. The A217 adx file should show up there. I would also select 'Reset dashboard' in ALDLDroid settings.
