If you’ve spent any time researching Bluetooth OBD2 scanners, you’ve probably landed on these two names again and again: the OBDLink MX+ and the Veepeak OBDCheck BLE. They’re two of the most recommended adapters in car forums, Reddit threads, and YouTube reviews — and for good reason. Both turn your smartphone into a capable diagnostic tool. But they’re built for very different budgets and very different users.
One quick note before we dive in: a lot of comparison articles online actually review the Veepeak OBDCheck BLE+ (the upgraded sibling) while titling the piece as if it’s about the plain OBDCheck BLE. That mix-up matters, because the BLE+ has broader AT-command support and better BimmerCode compatibility than the base BLE model. In this guide, we’re comparing the OBDLink MX+ specifically against the standard OBDCheck BLE, and we’ll flag where the BLE+ would change the picture.
Let’s break down exactly what you get for $30-ish versus $140-ish, and which one actually deserves a spot in your glove box.

Meet the Two Scanners
OBDLink MX+ is a professional-grade Bluetooth adapter built by OBD Solutions (the team behind ScanTool.net). It’s positioned as the adapter serious enthusiasts, technicians, and app developers reach for when accuracy and speed can’t be compromised. It’s the adapter recommended by FORScan for Ford diagnostics and by several BMW coding communities for stable connections.
Veepeak OBDCheck BLE is a compact, no-frills Bluetooth Low Energy dongle aimed at drivers who just want to read and clear codes, check live data, and do it without spending serious money. It’s one of the best-selling budget adapters on Amazon, largely because it’s one of the few sub-$35 dongles that reliably works with both iPhone and Android — most cheap clones only support Android.
Protocol & Vehicle Compatibility
This is where the real functional gap shows up, and it’s the detail most comparison articles skip.
Both devices support the five legislated OBD-II protocols:
- SAE J1850 PWM
- SAE J1850 VPW
- ISO 9141-2
- ISO 14230-4 (KWP2000)
- ISO 15765-4 (CAN)
That means for generic diagnostics — reading/clearing check-engine codes, viewing freeze frame data, checking O2 sensor and I/M readiness monitors — both tools do the same job on any 1996-or-newer OBD-II compliant vehicle.
The difference is what happens above that baseline. The OBDLink MX+ adds support for Ford MS-CAN and GM SW-CAN, the manufacturer-specific low-speed networks that carry data from body control modules, ABS, SRS (airbags), and TPMS. Standard ELM327-class adapters — including the Veepeak BLE — simply can’t see these networks. If you own a Ford or GM vehicle and want to pull ABS or BCM codes, or use FORScan for module-level diagnostics, the MX+ is one of the few affordable tools that gets you there. The Veepeak OBDCheck BLE explicitly does not support MS-CAN or SW-CAN.
One more thing worth flagging for 2024-and-newer vehicle owners: some newer Toyota, BMW, and GM models are shifting toward CAN-FD architecture on certain modules. Neither device markets full CAN-FD support, so if you drive a brand-new vehicle with this architecture, verify compatibility with the manufacturer before buying either adapter.
Speed & Live Data Performance
If you’ve ever watched laggy gauges on a cheap scanner while trying to diagnose a hesitation or misfire, you already understand why this matters.
The OBDLink MX+ is built for throughput. OBD Solutions markets it as delivering up to four times more data samples per second than competing Bluetooth adapters, which makes a real difference when you’re watching fast-changing PIDs — fuel trims, boost pressure, throttle position — during hard acceleration or load testing. For anyone data-logging a tune, monitoring boost on a modified engine, or diagnosing an intermittent electrical fault, that refresh rate is the entire point of paying more.
The Veepeak OBDCheck BLE uses a standard ELM327-class chipset. It’s perfectly fine for checking a handful of live PIDs, reading codes, or watching fuel economy estimates. But if you try to display 15–20 gauges simultaneously in an app like Torque or Car Scanner, expect noticeable lag. It’s a code-reading and light-monitoring tool, not a data-logging instrument.
App Ecosystem & Setup
Neither adapter comes with a screen — both rely entirely on a paired smartphone app, so app compatibility is arguably more important than the hardware itself.
OBDLink MX+ ships with the free OBDLink app (covers basic diagnostics, trip computer, and live graphs) and is also compatible with 18+ third-party apps, including FORScan, BimmerCode, Torque Pro, Carista, and AlfaOBD. The native app’s interface is dated compared to modern third-party apps, but most owners simply skip it and connect through Torque Pro or OBD Fusion instead — the hardware is app-agnostic.
Veepeak OBDCheck BLE does not include a bundled app. You’ll need a third-party app such as Car Scanner ELM OBD2, InfoCar, or OBD Fusion — these range from free to about $10. It also connects to vehicle-specific apps including BimmerLink, OBD JScan, and Dr. Prius, though full BimmerCode functionality (especially on G-series BMWs) is limited on the base BLE model compared to the BLE+.
Setup, step by step (applies to both):
- Plug the adapter into your vehicle’s OBD-II port (usually under the driver-side dash).
- Turn the ignition to “on” or start the engine — the adapter needs power to broadcast.
- Download your chosen diagnostic app (Torque Pro, Car Scanner, OBD Fusion, or the OBDLink app).
- Do not pair the adapter through your phone’s Bluetooth settings menu first — this is the single most common setup mistake with both devices, especially on iOS. Open the diagnostic app directly and select the adapter from within the app’s connection screen.
- On first connection, some apps run a short protocol auto-detection. Let it finish before requesting live data.
- Once connected, the app will display trouble codes and live PIDs.
If the device shows as “paired” in your phone’s Bluetooth settings but the app won’t connect, remove it from Settings entirely and reconnect from inside the app — this fixes the vast majority of connection complaints for both scanners.
Security
Security is one of OBDLink’s biggest differentiators, and it’s a genuinely underrated feature. The MX+ doesn’t continuously broadcast its presence like most cheap Bluetooth OBD adapters do, and it uses a multi-layered link security mechanism rather than a generic 4-digit PIN — reducing the risk of unauthorized access to your vehicle’s network while the adapter sits plugged in.
The Veepeak OBDCheck BLE uses standard Bluetooth LE pairing without the same dedicated security architecture. For most drivers this is a non-issue, but if you plan to leave the adapter permanently plugged in on a vehicle parked in public areas, the MX+’s security design gives more peace of mind.
Power Management
Both adapters include sleep modes designed to prevent battery drain if left plugged in continuously. The OBDLink MX+’s BatterySaver sleep mode is purpose-built for permanent installation — it draws next to nothing while asleep and wakes instantly when the ignition turns on, plus it includes overvoltage and load-dump protection. The Veepeak also enters a low-power sleep state, but it’s less commonly recommended by owners for indefinite, months-long installation — most Veepeak users plug it in only when needed.
Build, Warranty & Support
Physically, both are small, unobtrusive dongles that plug directly into the OBD-II port without a cable. The MX+ is slightly larger and includes a subtle logo/status light; the Veepeak is a compact “sandwich”-style dongle.
Where they really diverge is after-sale support. OBDLink backs the MX+ with a 3-year warranty and a 180-day satisfaction guarantee, plus free lifetime firmware updates. Veepeak’s standard warranty is considerably shorter — typically in the range of 6 to 12 months, depending on the retailer. If long-term reliability and manufacturer support matter to you (say, you’re recommending a tool to family or running it as a permanent fleet fixture), that difference is worth factoring into the price gap.
Real-World Use Cases
Ford/GM owner chasing an ABS or BCM code → OBDLink MX+. This is the single clearest reason to pay the premium — the Veepeak physically cannot read these manufacturer-specific networks.
Casual driver who just wants the check-engine light explained → Veepeak OBDCheck BLE. You’ll get the code, a plain-language description via your app of choice, and the option to clear it — all for a fraction of the MX+’s price.
Tuner or data logger monitoring live PIDs during a pull → OBDLink MX+. The faster refresh rate is the difference between catching a transient spike and missing it entirely.
Household with both an iPhone and an Android device → Either works, but note the Veepeak uses BLE for iOS and Classic Bluetooth for Android — meaning it broadcasts two different signal types, which occasionally confuses first-time users pairing on Android.
Fleet manager or shop wanting one tool that lasts → OBDLink MX+, largely on the strength of the 3-year warranty and permanent-installation-friendly power management.
Toyota/Lexus hybrid owner checking battery health → Veepeak works fine here paired with the Dr. Prius app for basic hybrid battery block readings; it doesn’t require MS-CAN/SW-CAN access.

Frequently Asked Questions
Is the OBDLink MX+ worth the extra money over the Veepeak? If you drive a Ford or GM vehicle and want access to ABS, BCM, or manufacturer-specific trouble codes, or you need fast live-data logging, yes. If you only want to read and clear generic check-engine codes on an occasional basis, the Veepeak covers that job for far less.
Can the Veepeak OBDCheck BLE reset an oil light or perform service resets? No. Neither the standard Veepeak BLE nor the OBDLink MX+ perform dealer-level service resets like EPB retraction or ABS bleeding out of the box; those require specialized service-mode tools or apps with paid manufacturer-specific modules.
Does either scanner work with electric or hybrid vehicles? Both are designed primarily for OBD-II compliant gas and light-diesel vehicles. Some hybrid functions (like Toyota/Lexus battery health via Dr. Prius) work on the Veepeak, and EV/PHEV support on either device depends entirely on the paired app — check app-specific compatibility before buying for an EV.
Why won’t my Veepeak connect even though it shows as paired in Bluetooth settings? This is the most common setup issue with BLE-based OBD adapters. Remove the device from your phone’s Bluetooth settings entirely, then open your diagnostic app and connect to the adapter from inside the app instead.
Is the OBDLink MX+ compatible with FORScan? Yes — it’s one of the most recommended Bluetooth adapters for FORScan on Ford, Lincoln, and Mazda vehicles, precisely because of its MS-CAN support.
Final Verdict
There’s no universal winner here — the right choice depends entirely on what you drive and what you need from the scanner.
Choose the Veepeak OBDCheck BLE if you want an affordable, reliable way to read and clear codes, check basic live data, and avoid a $10+ shop diagnostic fee every time your check-engine light comes on. It comfortably covers what 80% of drivers actually need.
Choose the OBDLink MX+ if you own a Ford or GM vehicle and need manufacturer-network access, if you’re logging data for tuning or performance work, or if you simply want the fastest, most secure, longest-warrantied adapter you can plug in and forget about.
Either way, both scanners are a significant step up from the unbranded $15 ELM327 clones flooding Amazon — and both will get you off the dealership’s diagnostic bill for good.
