Carista Bluetooth LE
Carista is a Bluetooth LE adapter that works with iOS. In addition to working with OBD Fusion, it is supported by other third party apps and also works with the Carista app.
Carista is a solid choice for a Bluetooth LE (BLE) adapter on iOS. As with other supported Bluetooth LE adapters, it is easy to connect and requires almost no configuration. We recommend this adapter if you also want to use the Carista app (requires a separate charge). If you are planning to use enhanced diagnostics, the Carista adapter will work with modules supporting legislated OBD2 protocols, and additional manufacturer specific protocols are not supported.
