Tonwon Pro BLE 4.0
The Tonwon Pro BLE 4.0 adapter uses Bluetooth LE and is compatible with iOS. This adapter includes an auto sleep function allowing you to leave it plugged into vehicle while not in use.
The Tonwon Pro BLE 4.0 adapter has been very reliable in our testing. It supports all legislative OBD2 protocols, and as with other generic adapters, does not support any manufacturer specific protocols. If you are planning on using this adapter with an iPhone/iPad, make sure you get the BLE version. Tonwon makes another Bluetooth 3.0 version that is only compatible with Android.
