OBD2 – How to connect your dongle to your Android phone.

This seems to be a major issue for some people ie not being able to connect the OBD2 app they have downloaded to their phone.

All the problems can be solved by NOT doing one thing

This one thing is NOT trying to connect to the dongle through the App.

There are exceptions to the rule but generally trying to connect to the dongle through your App is not going to work.

For one simple reason.

You have to connect your OBD2 Bluetooth device to your phone BEFORE you do anything else.

If your OBD2 dongle is not connected/paired with your phone your App will probably not “see” it and if it does “see” it, it will probably not connect to it.

Your must pair the Bluetooth device with your android device first.

To connect your OBD2 Bluetooth device to your phone.

Insert dongle into the OBD2 socket on the car.

Turn on the ignition, not the engine, just the ignition

OBD2 device will have power

Open your Android phone.

Go to the settings menu

Go to Bluetooth

Switch on Bluetooth if it is not on already

Find new devices

If your Android phone does not see the OBD2 device, switch off Bluetooth on the phone and switch it back on.

Still not joy?

Unplug the OBD device and reconnect it to the car.

Repeat until your phone sees the device.

Pair your phone to the newly found OBD2 device.

Password is usually 1234

When its paired you are good to go

Open the Android App of your choice.

Follow the procedure to allow it to use the paired OBD2 dongle.

And that is it.

Like I said at the start. The biggest problems people have (in my experience) is trying to connect with the dongle through the downloaded App.

What can add to people’s confusion is the fact the OBD2 dongle may even show up in the App itself.

But the App will not be able to connect to the device until it has been paired.

If it has not been paired it will not connect.

Hopefully this article will help you connect your Android device to your OBD2 Bluetooth device!
