No, an OBD2 app is required but not included. There are many great third-party OBD2 apps available to download (some may require purchase) from Google Play Store and Apple App Store. What features you can get mainly depends on the chosen App.
For generic OBD2 functions, we recommend Car Scanner ELM OBD2, Inforcar, or OBD Fusion (paid). They cost from free to about $10.
Some advanced Apps require subscription or are more expensive like BimmerCode or OBD JScan.
For advanced vehicle-specific features, please see App recommendations listed below:
Toyota & Lexus: OBD Fusion, Carista OBD
FCA: OBD Fusion, OBD JScan, AlfaOBD
Ford, Lincoln & Mazda: OBD Fusion, FORScan Lite
Nissan & Infiniti: OBD Fusion, Carista OBD
Volkswagen/Audi/Seat/Skoda: Carista OBD
BMW & Mini: BimmerLink, Carista OBD
Others: GaragePro Car OBD2 Scanner

Yes, the OBDCheck BLE is compatible with Apple iOS devices via Bluetooth LE. You should not pair or connect in iOS Bluetooth Settings; instead, please directly connect in the App. Note: it does not use WiFi.

It works with Android phones and tablets, but may have compatibility issue with some Android head units due to their lack of support for some Bluetooth profiles and we do not have a compatibility list due to the complexity of the market. For some Android head units, you may check the Bluetooth settings and see if the pairing pin is disabled or incorrect. If this still does not help, please contact us or the head unit manufacturer for assistance.

You can leave the adapter plugged in for a few days if your car battery is not too old, or the car is driven frequently. If you leave your car sitting for more than 1 week, we strongly recommend that you remove the device.

Most EVs (including PHEVs) do not follow standard OBD II specs, so you may need a capable App to connect, for example Car Scanner ELM OBD2 (select the corresponding connection profile), ABRP, LeafSpy, EVNotify, EV Watchdog, MyGreenVolt, CanZE, etc.

Most OBD2 Apps only provide basic emission-related check engine light diagnostics. You will need a capable App that can do enhanced diagnostic on your specific vehicle, for example OBD Fusion, OBD JScan, AlfaOBD, Carista OBD, etc. Contact Veepeak or the app developer to check if it’s available on your vehicle. Oil change or maintenance required lights cannot be read or reset since there is no error code for them.

Readable parameters depend on what's installed on the OBDII system by the manufacturer. Generally, newer vehicles will give more readings and faster refresh speed.

The transmission (fluid) temperature is a manufacturer specific PID so it’s not read by most generic OBD2 Apps. Please contact Veepeak customer support for App recommendation (similar to FAQ 6) or search for the custom PID information on the web & add it in the App. This applies to other manufacturer specific PIDs.

Currently the OBDCheck BLE does not support all the coding options in BimmerCode for G series. Please choose other adapters as recommended by BimmerCode.

No. It only works with 2008 and newer BMW models when using with the two Apps.

Please visit the Amazon product page and click “videos” below the product images.

First check if the cigar fuse of your vehicle is in good condition. You can also try with another vehicle to verify. If the OBD2 port of the vehicle is fine, please contact us for help.

This device uses Bluetooth LE for iOS devices. You will see this error when trying to pair with it from the iOS Bluetooth Settings. You do not need to connect with VEEPEAK here. Please restart your iOS device so “VEEPEAK” shows up again under “Other Devices”. Then start the App and directly connect in the App (refer to App connection tips).

(1) Turn off Bluetooth and turn it back on. Try pairing a few more times. Sometimes it helps.
(2) Restart your phone, disconnect other Bluetooth devices, turn off WiFi/cellular data and try again.
(3) Clear Bluetooth cache/storage: Settings – Apps (show system) – Bluetooth – Storage & Cache, clear them and RESTART the phone (the route may be slightly different for different brands).
For Android head units, check the Bluetooth settings and see if PIN is enabled or the default pairing PIN is correct (should be 1234).

Make sure the device is not connected to other phones or tablets. Please restart your phone, turn off Bluetooth and turn it back, refresh the Bluetooth list and wait for a few more seconds.

This can happen with a few Android phones but as long as it is paired successfully via Bluetooth, you can just start the app to connect (for Torque Pro app, please switch to the app to select Bluetooth device as soon as the device is paired). It may show as saved, paired or previously connected, but it's actually connected.

Make sure the App is compatible, and you have made the correct App connection settings and granted the App permissions;
Remove and re-install the app (especially when you have an OS update);
Try with a different App such as Car Scanner ELM OBD2, Infocar, which are free to test.

Make sure your vehicle is OBD2 compliant and the OBD2 connector is in good condition;
Check if your vehicle is supported by the App;
Make sure ignition is turned ON or start the vehicle to try;
Make sure it fits well in the OBD2 port. Try to push it a little harder into the OBD2 port if the contact is loose;
Try it on another vehicle to check if it’s the problem with the device.

Keep the device as close as possible to your phone, and close other Apps; update the app to the most up-to-date version; try with a different app (Car Scanner ELM OBD2 or Infocar) to see if it happens again.

Try with a different app and see if it makes any difference.

Try with a different App. If there are non-check engine lights on the dashboard, you may need a capable App to read these codes. Contact us with your vehicle make/model/year for App recommendation.
