Totally aggree, as this is precisely what i do. the only thing to add is that there can be a reduced number of PIDs used with BT as opposed to USB (but not an issue for most people). The number is dependent on precise ones tested.As you are in the UK then I suggest you speak to / look at Gendan.
I normally recommend that vehicle changes, especially Proxy actions are done via a proper cable with a proper ELM/OBDLink-SX device and not via Bluetooth this can be unreliable.
However for simple parameter monitoring, especially when driving, then Bluetooth is certainly the safest and most convenient way.
Many thanks for the advice, I've just purchased a bluetooth device recommended by Gendan, this appently works with ios apps, have you used any ios apps?Totally aggree, as this is precisely what i do. the only thing to add is that there can be a reduced number of PIDs used with BT as opposed to USB (but not an issue for most people).

I personally have never used Apple products. I believe they maintain much stricter control over hard ware/ software so it may not work. Another point with Apple they require an annual fee to use Multiecuscan, for windows it is "lifetime" with 1 years updates.Many thanks for the advice, I've just purchased a bluetooth device recommended by Gendan, this appently works with ios apps, have you used any ios apps?
