Hi,

I bought & use OBDLink MX+ Bluetooth; it comes with a good diagnostic app that I have on Samsung phone in addition to Bimmercode. Both work well; have used it on a friend's 7 series & my son's Mini to read error codes.

One thing to be aware of is to make sure all other Bluetooth signals are off so as to minimize any problems -- so I turn off my car's bluetooth & leave my smart watch in the house when I am using OBD II bluetooth devices

Hope that helps
