Trouble connecting 1320 BT ALDL OBD1 adapter to TunerPro RT


Have been using the 1320 Electronics 12-pin OBD1 Bluetooth Adapter for a couple of years now with an Amazon Fire Tablet & ALDLdroid to tune the TBI on our 1990 Grand Wagoneer. Had never tried to use it with Windows / TunerPro RT until last weekend & have had a fit trying to get this configuration to work. After extensive searching online & playing w/BlueTooth settings/re-installed drivers/deleted/re-paired/defined COM ports - i have it paired to my laptop successfully on COM4, and defined to TunerPro RT as such; but, i'm unable to get TunerPro RT to recognize & connect to it. I saw this thread: http://www.gearhead-efi.com/Fuel-Inj...ro%20bluetooth, which aligns with what i'm seeing. Saw & followed John@1320's recommendation to change the baud rate from 4800 to 9600; all dip switches are Off. Am seeing the status change from "DA: Not Connected" to "DA: Connecting..." back to "DA: Not Connected" quickly, when attempting to connect. Wondering where else to look? Would love to pull a data log this weekend.


Back story: went w/the bluetooth option, as the PO's mechanic wired up the system all under the hood, so a cable'd version is a no-go, without a major re-wire. Am looking at doing that, but wanted to get the TBI to a known good place, before doing so.
