ELM327 Bluetooth Adapter OBD2 Scanner Connector ELM 327 Bluetooth Adapter OBD2 Scanner for iPhone Android and iOS Phone OBDII OBD 2 Wireless Code Reader Diagnostic Scan Tool with Free Faslink X APP

got it for my mobile service truck and personal use. nice to have multiple different scan tools and this one works with multiple apps.

Cannot pair BT via regular phone settings, must use their app.Their app is only available for older android devices, will not allow me to install on Pixel 7.Dug out my old phone. Was able to download, but as you can see in the pic, will not find the device to pair.It shows up in the phone BT menu, but you cannot pair.Had to return it.

It said that is wifi and it is not, is just bluetooth

Great tool for price

Maybe it's just me:I have an old 70's Chevy pickup truck with an LS2 dropped in. The computer and transmission were taken from a wrecked Cadillac Escalade. It's a total hot rod and mishmash of parts. Every once in a while the check engine light will come on and I never quite figure out what it's coming from. Eventually it'll reset itself. I knew that there was no way I could be lucky enough to have everything magically appear on the App. But, it did get a few things. Next time the check engine light comes on, I will see what's going on.The Good:My other car is a 2021 Subaru. It has a few idiot lights on so I plugged the ODB2 Scanner in and started poking around. I had no idea this much information was coming out of the port under the dash. I resolved the problem quickly and played around for another 30 minutes just to see what information I could pull up.The Not So Good:The FasLink application was available for my iPhone and it worked okay. However, There's a scanning option that didn't seem to be able to read anything. I ended up putting in my information VIN, make, year by hand. This bit was really messy in the interface. There was a narrow cluster of years selectable and it seems 2021 wasn't on the list. The long list of autos was difficult to navigate because I had to scroll past Maserati, Bugatti, Lotus, and several entries for GMC before I landed on Subaru. To make matters worse, the are not in any kind of order. Alphabetic? Nope. Scroll... scroll... scroll... Also, I'm not really sure what putting this information really did for me. Maybe it made certain sensors and readings available to me. No, the hodge podge Chevy which in no way could be entered (Chevrolet is missing from the list!) had all the same check boxes for real-time display.I think other apps are out there that can communicate with this ODB2 scanner. I will try some of them just to see. Or you may have a 2020 Bugatti that will effortlessly connect to the FasLink app. YMMV.

This is a tiny little code reader that uses the phone as an interface. I was skeptical about its functionality compared to the Snap-On one my mechanic uses, but it does the same basic code-reading and system performance.The app:The Faslink X app looks nice but is not very good. It is free, the full version. It works and does the essentials, but the Car Scanner app is so much better. Car Scanner free version has more functionality than Faslink X. It showed me more data thru an interface that doesn’t have bugs. The Faslink app looked pretty, bu it was slow to respond, felt barebones in terms of actual performance, and has buttons that do nothing. Car Scanner showed me the same info more easily. It also has a paid premium version that offers more functionality.The Unit:Couldn’t be simpler. Nothing to charge or switch. Plug it in, it lights up. Open phone app. App reads and connects to device in-app. Nothing to it. Nothing to learn, I got it to work right away without reading any instruction book. The app guided me thru the three-step process. (Both apps I trued do this. Click connect, select the OBDII unit, start scanning. No need to open bluetooth settings and connect manually, like I have to do with my speakers.Came in a minimal white cardboard box with a custom-cut foam insert. Adequate for storage. Since it came with no cap for the connector, no bag, no case, the box is all I have to store it. It’s small enough to keep it in the box and keep in the glovebox, but I’d have preferred a fitted cover, something smaller. Or a reusable box, instead of the basic white cardboard with Amazon sticker on it. It’s something I’ll use sporadically, most of the time sitting in the glovebox, so it would be nice to have it stored in something more attractive and less bulky.Unit itself is of adequate durability. It’s built like a Sega game, and of greater durability than a Sega game, so like a Sega game, it should last decades. I’m more concerned whether the phones and apps will still work in 20 years than I am this bluetooth unit.Good value. Able to do a reset. Reads the codes, displays what they mean, links to web to read more on the codes. Should become much more popular as people discover these exist, this is such a handy tool.

Not compatible with anything newer than Samsung Galaxy S8. Useless.
