Looks like this has been asked time and time again but all I am finding is conflicting information.
I have tried numerous different bluetooth and wifi OBD2 readers and none of them appear to work, my current wifi adaptor refused to even connect. Not a RaceChrono issue of course but infuriating at the track when nothing works, I do have a radio with bluetooth in the car so wonder if that conflicts with the reader.
So my question is, are there any compatible USB readers about? A hard wired connection is always going to be better than wireless and I don't want to keep wasting money on bluetooth and wifi adapters that never work.
