Brian,
Thanks for responding.
Apologies for my confusing statements.
When using the OBDLink app, there appeared to be some connectivity with the dongle but information like the VIN didn't appear correctly.
However, my reason for purchasing the OBDLink CX was to use an Android app called ABRP.
This app can use an OBD dongle to track battery condition in an EV.
Even though the OBDLink app didn't seem to work as I expected, when I tried to connect ABRP to the OBDLink CX, it took a few tries but eventually connected.
So, now I'm happy that the OBDLink CX is doing what I wanted.
So all good and appreciate your and Shawn's replies.
All the best.
