I have no way of confirming that this works on stock Android, but
this StackOverflow thread says that Bluetooth is an option. The answer says that custom ROMs work, but this was in 2012, so it may have been implemented in stock Android by now, or it may be an option to flash CyanogenMod on your FTC phone (I don't know if it's FTC legal, but I'm not a cop).
Other threads that I found by googling "adb bluetooth" give some alternate information and steps.
