The dongle you speak of is identified by a MAC address(Machine Address) called Bluetooth Address not UUID. UUIDs are for services such as SPP, OBEX etc. Try searching for the dongle's bluetooth address using a free version of Torque or some bluetooth application that will reveal its Bluetooth Address.Use that address to connect with it.

I found a lot of OBD2 BTLE dongles changing their UUID on every startup. Better scan using the (fixed) service UUID rather than the device address.
