I need to scan the various OBD-2 codes, so I bought a copy of ScanMaster (by Westinghouse; and also by the company that makes a ScanMaster), at some point.
My cell phone has a built-in OBD-2 connection. I bought the scanmaster ELM (v2.1), for the ability to scan the EOBD codes.
This is the ELM-327 for Windows & Mac, with OBD-2 support.
The software version listed is 1.1 (Windows) or ELM v2.1 (Mac).

Here is a document discussing what the different Bluetooth OBDII interfaces have to offer:
Theoretically, an OBDII scanner, on a smartphone or tablet, should be able to communicate with the engine on a car with the right connector.
What is it you are trying to achieve that only a dedicated OBDII scanner can do?
A:
This is an OBDII interface that works on Android without needing to be rooted.
It uses a custom build of the Bluetooth OBDAI2 standard and relies on Google Play Services to communicate.
No configuration, no user input, not even any login needed.
The Bluetooth module "Diskscan" was used as a Bluetooth serial/RS232 interface, a cheap 4$ USB-BT chip was used.
The connection is USB or Bluetooth. You just need to change between the two in the settings.
The programming is very straightforward, using Android Studio (or any IDE you prefer) is super easy.
It doesn't have a GUI, but it can run code right from the menus, and most of the functions are fairly self-explanatory.
The module can output many (10) different protocols, in addition to the OBDII standard protocol, you can get everything from the CAN bus, to the fuel injection system, and much more.
The scan data is recorded into the XML file /data/data/de.scan_master.dp.scan-master/files/scan-daten, you can get a file browser on Android and access the data directly.
The FMU messages can be read and output using the be359ba680
