Adapters and gear we’ve picked to work with RedlineAi. Right now: the Bluetooth OBD-II adapters that pair with the in-browser live reader — so you can read your codes and live engine data with no app.
Parts for your car
Pick your year, make and model and shop brakes, filters, spark plugs, sensors, batteries, wipers and more — every search tailored to your exact vehicle. Works for everyone, no login needed.
What to look for
The live reader talks to your car over Web Bluetooth, so you need a Bluetooth 4.0 / BLE (Low Energy) adapter. Bluetooth “Classic” dongles, WiFi adapters, and USB adapters will not work — the browser can’t see them. Every adapter below is BLE and confirmed compatible.
iPhone & iPad won’t work
Web Bluetooth isn’t available in Safari or Chrome on iOS, so the live reader does not work on iPhone or iPad at all. Use Chrome on Android, or a desktop/laptop. (Demo mode works anywhere.)

Bluetooth OBD-II adapters
These plug into the port under your dash and pair with the RedlineAi live reader over Web Bluetooth. Every one below is Bluetooth LE (4.0+) and confirmed to work with the reader.
OBDLink CX
The most reliable pick. Bluetooth 5.1 BLE, fast and rock-solid, and it plays nicely with Web Bluetooth and fussier vehicles. If you want it to "just work," get this one.
Vgate iCar Pro BLE 4.0
The budget favorite. True Bluetooth 4.0 BLE — make sure you choose the BLE 4.0 version, not the older "Classic" one. Great value for reading codes and live data.
Veepeak OBDCheck BLE
Compact, dependable, and inexpensive. A solid no-frills BLE adapter that pairs cleanly with the live reader.
Veepeak OBDCheck BLE+
The step-up Veepeak: broader protocol coverage and a sturdier build, still Bluetooth LE. A good middle-ground between the budget pick and the OBDLink.
