Ancel AD310 BT Review: The Best-Selling Code Reader, Now With Bluetooth
Published: August 11, 2024 · Last updated: June 4, 2026
The Ancel AD310 BT is the Bluetooth version of Ancel’s best-selling AD310 code reader. You get the same reliable handheld reader, plus the option to connect it to your phone and use the Ancel app. I tested it alongside the classic non-Bluetooth AD310. It’s an interesting concept, a traditional code reader with a Bluetooth bridge to an app, but in practice the app mode doesn’t add as much useful function as you’d hope. It’s engine-only. Read on for what the Bluetooth actually buys you.

What it’s actually good at
As a standalone code reader it’s the proven AD310, and that’s a genuinely solid tool. In OBD2 mode it’s identical to the classic AD310: read and clear engine codes, readiness monitors, freeze frame and engine live data, with around 20 text values and 15 graphable, which is good for a cheap reader (many in this price can’t graph at all, or only four or five values). Connection is instant, build quality is excellent, and it works on basically any OBD2 car. The only physical difference from the old one is a slightly brighter screen.
The Bluetooth app mode does add a few nice touches, mainly convenience. Through the Ancel app you get faster, easier-to-read live data on your phone (just tap a value to graph it, no menu digging like on the handheld), expanded fault-code info with likely causes, a battery test, performance and acceleration tests, and a customizable dashboard. For viewing live data, the phone screen is simply nicer and more responsive than the small reader display.
Where it falls short
The Bluetooth mode doesn’t add as much real function as the concept suggests. Most of what the app does, code reading, live data, freeze frame, you can already do on the reader itself. The extras (battery test, performance dashboards) are pleasant but not essential, and a cheap ELM adapter plus a good app does the same phone-based job for less. So you’re paying for a clever two-in-one, not for new capability.
It’s engine-only. No full-system access, no ABS or airbag, no bidirectional, no coding. It’s a code reader with a Bluetooth twist, nothing more, which is why the value is on the weaker side for the price.
Who should buy this
Yes, buy it if:
- You want the reliable AD310 reader but like having the option of a phone app too
- You value a faster, nicer screen for viewing live data via your phone
- You specifically want a standalone reader and app in one device
No, look elsewhere if:
- You just want a classic code reader, the cheaper non-BT AD310 is identical in OBD2 mode
- You mainly want phone-based diagnostics, a cheap ELM adapter does the same for less
- You want anything beyond engine codes, this is engine-only

Final word
The Ancel AD310 BT is a well-built, reliable code reader with a clever Bluetooth twist: it’s the proven AD310 in OBD2 mode, plus a phone app that makes live data nicer to read and adds a few extras like a battery test. The catch is the app doesn’t add much you can’t already do, and a cheap ELM adapter covers the phone side for less, so the value is modest. If you like the idea of a standalone reader and app in one and don’t need more than engine codes, you’ll be satisfied. If not, the classic AD310 or a cheap ELM makes more sense.
