Bought this software along with a bluetooth dongle on the compatible list but it has never worked properly and keeps disconnecting and reconnecting again. I contacted the developer who asked for a copy of the debug log which I sent but he never got back to me with a solution. £50 completely wasted.
Compatiblity a bit patchy, finally bought a ODBLink MX and this does connect, but shows some errors. Shame you can't download a trial version to check hardware compatibility before spending the not inconsiderable price for purchasing the app.
