I haven't tried it yet but my guess is that if you have a bluetooth dongle (ELM 327) that you pair the dongle with the tablet for the connection. No cable is necessary. Note that a bluetooth connection does not allow you to read or load maps, just perform diagnostics and testing according to the website.
The other option is to use your existing OBDII to USB cable and add the USB to Micro-USB adaption (shown below) to allow it to plug into the tablet.
