Purchase restoration and transfering FAQ

Transfer purchases between different platforms and app marketplaces.

To understand the license purchase system for using the Pro version, you must understand the main idea: there are 3 different applications, each of which is a separate legal entity with its own separate license:
1) Car Scanner ELM OBD2 for Google Play
2) Car Scanner ELM OBD2 for Apple AppStore
3) Car Scanner ELM OBD2 for Huawei AppGallery

When you buy a license from an app store (Google Play, Apple AppStore, Huawei AppGallery) you agree to the terms of this app store. Each app store policy states in some form or another that all purchases are valid only within that app store and if the app store is installed on your device. The app store acts as a technical means of copyright protection, in other words, it is the app store that checks and activates your license.
The conclusion follows from this: it is impossible to transfer purchases between different versions of the program.

If you purchased the application from Google Play, your license is valid only for the version installed from Google Play and if Google Play is available on your device. You will not be able to activate your purchase on the Huawei AppGallery or Apple AppStore version of Car Scanner.
If you purchased the program from Huawei AppGallery, your license is valid only for the version installed from Huawei AppGallery and if you have Huawei AppGallery on your device. You will not be able to activate your purchase on the Google Play or Apple AppStore version of Car Scanner.
If you purchased the program from the Apple AppStore, your license is only valid for the version installed from the Apple AppStore and if you have the Apple AppStore on your device. You will not be able to activate your purchase on the Google Play version of Car Scanner or the Huawei AppGallery.

General questions related to versions from Apple AppStore, Google Play, Huawei AppGallery:

1. I forgot/lost/changed my account. Is it possible to transfer the purchase to my new account.
No you can not. If you have lost access to your account, then you have lost access to all purchases that are associated with this account. I can’t help in solving this problem, because this is the scope of the app store. Regular developers do not have any technical ability to transfer purchases between accounts. You can contact app store support to regain access to your account.

2. I changed my phone and I no longer have the app store through which I bought the app. Can I transfer my purchase to another app store?
No you can not. It is the app store that provides confirmation, verification and activation of all your purchases.
Sometimes it is technically possible to install an app store on a new phone. For example, the Huawei AppGallery app store can be installed on almost any Android phone. On some phones without Google Play, it is possible to install Google and Google Play services.
So you have two possible solutions:
1) If it is technically possible: install on the new phone the application store through which the purchase was made and restore (activate) it.
2) Make a new purchase through the store that is installed on your new phone.

3. I don’t remember which version (through which app store) I bought. What should I do?
If you had an iPhone/iPad, then you could only make a purchase through the Apple AppStore. Your purchase is valid on iPhone/iPad only. Just use the same Apple ID in your iPhone/iPad settings and click the “Restore purchases” button on the in-app purchases screen if the Pro version didn’t activate automatically.
If you had Android, you’ve it bought through Google Play or Huawei AppGallery. Try both markets.

4. I bought through Google Play, how can I restore my purchase?
Just use the same account and install the program from Google Play. The Pro version activates automatically, or you need to click the “Restore purchases” button on the purchases screen. If the purchase does not recover, here are the possible causes and solutions:
1) If you have multiple Google accounts in Android settings, you need to temporarily log out of all “extra” ones, leaving only the account that was used to purchase Car Scanner.
After that, activate the Car Scanner and you can log back into the rest of the accounts.
2) If something is blocking the program’s access to the license verification server, then allow access. Sometimes you need to install and activate any free VPN application.
3) Check if the date, time and time zone are correct in your phone settings.
4) Reinstall the application.
If none of these methods worked, then send me the order number (you can find it in the purchase confirmation email from Google Play, it always starts with “GPA”) and a screenshot of the error message when trying to restore the purchase. It is very important to send both. Instead of the order number, you can write the e-mail address of your

5. I bought through Huawei AppGallery, how can I restore my purchase?
You need to install Huawei AppGallery, log in to your AppGallery account, install Car Scanner from AppGallery (if there is an installed version of the program from another source, you must first uninstall it). The Pro version activates automatically, or you need to click the “Restore purchases” button on the purchases screen.

6. I bought through the Apple AppStore, how can I restore the purchase now?
You need to use the same Apple ID account in the AppStore on your iPhone/iPad, install the app from the AppStore. The Pro version activates automatically, or you need to click the “Restore purchases” button on the purchases screen.

7. I bought through the Apple AppStore, Google Play or Huawei AppGallery for a long time and suddenly the program switched to free mode.
Most likely you bought a subscription with a time limit and the period you paid for has expired. These subscriptions should auto-renew, but they don’t renew if the app store fails to charge you.

8. I can’t do ANYTHING! What should I do?
If you are unable to describe in detail what exactly you are not able to do, then you do not want my help.
I don’t help those who can’t do ANYTHING. Either you don’t get something specific and I help you solve this problem, or you are on your own. Harsh, but honest.

Bluetooth connection troubleshooting

An exhaustive list of possible connection problems with the ELM327 adapter.
Attention! This list only refers to the connection to the ELM327 device itself and does not cover connection problems with the vehicle ECU.

Issue #1. You have selected the wrong device in the program settings.
A very common problem is when users, instead of selecting the ELM327 adapter in the program settings, select some other device for connection (for example, a car multimedia system).
Solution: Go to Settings -> ELM327 Adapter -> tap the “Device Name” field to select the device and select your ELM327 adapter there. Usually the name of the adapter is OBDII or something related to the brand of the adapter (eg Viecar, V-Link, OBDLink).
Remember: the name of the adapter is never associated with either the brand of your car or the brand of your phone. Therefore, you do not need to choose “MyCar”, “Opel”, “Samsung” or “iPhone”!

Issue #2. You have multiple adapters with the same name and selected the wrong adapter. Adapters can have the same name (usually OBDII) but a different address. The connection is made not by the name of the adapter, but by its address. Therefore, if you have not selected the adapter that is connected to the car’s connector, the program will not be able to connect to it.
Solution: Go to Settings -> Adapter -> tap the “Device Name” field to select the device and select the correct ELM327 adapter there.
To eliminate possible confusion, I recommend removing all unnecessary adapters from Android settings.

Issue #3. You have selected the wrong connection type.
Solution: Most Android adapters work via “classic” Bluetooth, but sometimes there are adapters that work via Bluetooth LE (4.0).
IMPORTANT! Bluetooth LE is different from classic Bluetooth. These are fundamentally different ways of wireless communication.
If your adapter only supports classic Bluetooth, you must select the Bluetooth communication method.
If your adapter only supports Bluetooth LE (Kiwi 3, OBDLink CX), you must select the Bluetooth LE (4.0) communication method.
If your adapter supports both Bluetooth and Bluetooth LE, then on Android it is recommended to choose classic Bluetooth, but on iOS you have no choice and are forced to use Bluetooth LE anyway. Adapters that only support classic Bluetooth will not work on iOS. With one exception: OBDLink MX+ (they have a direct contract with Apple, so they were allowed).
The Bluetooth version on your phone does not matter.
Thinking that Bluetooth LE will be faster than Bluetooth is also a mistake.

Issue #4. Another program is occupying the communication channel with the adapter.
Solution: Disconnect and force quit another program. Sometimes this is not exactly a trivial task.
On iOS, you need to trigger a task switch and force close all other OBDII apps.
On Android this may not work. the program may leave behind a background service connected to the adapter, so it is better to use the shutdown methods that are in the program itself.

Issue #5. The adapter fell asleep / hung / turned off.
Solution: Remove the adapter from the socket and insert it again. If the adapter has a power button, make sure the adapter is turned on, otherwise press the button.

Issue #6. Freezing or glitches of the Bluetooth stack (drivers) on your phone/tablet.
Solution: Turn Bluetooth off and on. If it doesn’t help, restart your phone.

Issue #7. No rights to access Bluetooth.
Solution: Allow the app to access Bluetooth.
Android 6.0-11 (and some 12): Android Settings -> Applications -> Car Scanner -> Permissions -> “Location/Geolocation” but it’s true).
Android 12 and above: Android Settings -> Applications -> Car Scanner -> Permissions -> Nearby Devices
iOS: iOS Settings -> Privacy & Security -> Bluetooth -> enable Car Scanner there

Issue #8. You have not enabled Bluetooth or you have not enabled the adapter.
If Bluetooth is turned off on your phone, you need to turn it on.
If your adapter has a power button, then you need to press it to turn it on.

Issue #9 (Android only): No permissions to access Bluetooth.
In addition to the permissions described in issue #7, there is another permission to access Bluetooth, which is not displayed anywhere and is automatically given to the program by the operating system at the time of installation. But sometimes, the Android OS doesn’t. Just a system glitch during the installation of the program and as a result, the program cannot use Bluetooth.
Solution: reinstall the program.

Issue #10. The adapter is dead.
This happens much more often than you think. Therefore, if none of the above reasons helps, you just need to buy a new adapter.

BONUS. What to do if the Car Scanner does not see the adapter at all.
Solution: This problem can have various causes.
Reason 1: You chose the wrong connection method. For example, your adapter only supports classic Bluetooth, and you have selected Bluetooth LE (4.0). In this case, read the solution to problem #3 carefully.
Cause 2: The adapter is busy with another program.
Read the solution to problem #4 carefully.
Reason 3: not enough rights.
Read the solution to problem #7 carefully.
Reason 4: The adapter is frozen.
Read the solution to problem #5 carefully.
Reason 5: Bluetooth on the phone is frozen / glitched.
Read the solution to problem #6 carefully.
Reason 6: The adapter has died.
Read the solution to problem #8 carefully.
Reason 7 (Android only): Starting with Android 6 and above, in order to find new devices (Bluetooth LE devices are always considered new), you need to enable geolocation.

Custom sensors (PIDs)

Car Scanner allows you add custom sensors (also known as “custom PIDs”) to get data, defined by your car manufacturer.

To create custom sensor you need to know at least 2 things:
1. How to make a request to ECU to get the data you need:
Command = Mode + PID,  e.g. 010C for engine RPM
Header = address where to send request, e.g. 7E0 for CAN 11bit protocol. You can leave header blank. In that case default functional header for current protocol would be used. Most of custom PIDs requires correct header!

2. How to decode received data: Formula (Equation).
To point at certain bytes in response use latin letters: A, B, C, D .. Z, AA, AB, .. AZ, BA, BB, .. BZ, … etc. , where letter A stands for 1st byte in response, letter B stands for second byte in response, etc.
Attention! Formula is case sensitive!
To determine first byte, Car Scanner skips some bytes in response from ECU: header bytes, data length, response to certain mode marker (e.g. mode 01 -> response marker 41) and PID id.
Example: request 010C (engine RPM) would give you response: 7E804410C0C9C, where Car Scanner would skip 7E804410C.
So we have only 0C9C data left.
Letter A would mean 0C, letter B would mean 9C

You can use mathematical operators like *, /, , +. Example: A+B
To change calculation order use brakets ( ), like: (A*256+B)/4
You can use floating point numbers in formula using dot “.”: e.g. A+13.54

Bitwise functions supported:
Bitwise unary complement: @~
Bitwise AND: @&
Bitwise exclusive OR: @^
Shift left: @<<
Shift right: @>>
Examples: A@<<16, C&7, etc.

Additional functions (funtion arguments should be always separated by “,“):
GetBit(A,N), where A – byte number, N – bit number, from 0 to 7
SIGNED(A), signed(A), Signed(A) – treat byte as signed (-128 .. 127)
ShortSigned(A,B) – treat 2 bytes as 16-bit signed value
And(A,B) – bitwise AND, same as A@&B
Shr(A,B) – bitwise shift right, same as A@>>B
Shl(A,B) – bitwise shift left, same as A@<<B
MAX(A,B) – returns maximum value from A and B
MIN(A,B) – return minimum value from A and B
abs(A) – return unsigned value, e.g. abs(-1)=1, abs(-123456)=123456, abs(123456)=123456
FLOAT32(A,B,C,D), float32(A,B,C,D) – returns IEEE 754 floating point value from 4 given bytes.
FLOAT64(A,B,C,D,E,F,G,H), float64(A,B,C,D,E,F,G,H) – returns IEEE 754 floating point value from 8 given bytes.

if(A,B,C) – logic function, if A=1, returns B, else returns C. You can use “=” or “<” or “>” for comparison.
Example: if(A>5;5;A).  If A greater than 5, return 5, else return A. With A=6 this would return 5. With A=3 this would return 3.

Car Scanner doesn’t support formula, that points to another sensor or another PID.

You can add commands, that would be executed BEFORE and after requesting PID (Start diagnostic command and stop diagnostic commands). This commands should be fully qualified ELM327 commands, separated by “;” or “,” or “\”. Example: ATCRA7E8,ATFCSH7E0,ATFCSD300000

Action PIDs.
Action PIDs are executed when you tap on them. Response is not decoded.
Example of usage: create custom action pid for some command, that starts a routine, like forced DPF regeneration.
Don’t forget, you still need to know header and command for that.

Name and Short name fields can be entered as you wish.
Minimum and maximum fields can be skipped.

Configuring Bluetooth connection on Android

First of all make sure, that you have OBDII ELM327 adapter with Bluetooth.

You should plug it inside the diagnostic socket in your car (known as “OBDII socket”) and turn on ignition or start the engine. If your adapter has a power button on it’s body – press it.

Step #1: Pair your phone/tablet with OBD2 adapter. If you have already done that – skip to Step #2.

WARNING! Depending on different Android versions, pairing may be done in some other way.

Open Android settings and locate Bluetooth section. Turn on Bluetooth and wait until your adapter would be discovered.

Usually it’s called “OBDII”, “obd2” or something like that. If it’s branded, it could be called as it’s brand (e.g. “Viecar”, “VLink”, etc.). Please, note, that it’s NEVER called like your car brand or “MY CAR” or something like that.

Tap on it to pair your phone/tablet with OBD2 adapter. Adapter would ask you for PIN-code.

If you don’t know PIN code, check your adapter documentation. Usually it’s “1234”, “0000”, “7890” or “1111”.

Step #2: Select adapter in Car Scanner.

Open Car Scanner and go to Settings (gear icon in the top-right corner)

Tap on “Adapter” (in old versions – “Connection”)

Select Connection type: Buetooth

Tap on “Select device” and you’ll see device selection screen.

Tap on your adapter’s name.

That’s all, now you have adapter selected and you need to go back and tap on big green “Connect” button.

Next time all you need to do is just tap on “Connect” button

Don’t forget to press power button on your adapter before connecting, if it has one.

Configuring Wi-Fi connection to ELM327 adapter

First of all make sure, that you have OBDII ELM327 adapter with Wi-Fi connection type. You should plug it inside the diagnostic socket in your car (known as “OBDII socket”) and turn on ignition or start the engine. If your adapter has a power button on it’s body – press it.

Step #1: Open your Phone/Tablet Wi-Fi settings (NOT Car Scanner settings) and turn on Wi-Fi.

Locate Wi-Fi network, created by ELM327 OBDII adapter and connect to it.

Usually it’s called “OBDII”, “OBD2”, “WIFI_OBDII” or something like that. Sometimes it’s name has something familiar with your adapter brand (e.g. VGate adapters usually have “VLINK” network name).

Most of adapters doesn’t require password for WiFi network, but if your adapter requires that – follow documentation that comes with your adapter.

Please, note, that it’s NEVER called like your car brand.

iOS
Android

Step #2. Car Scanner setup.

Open Car Scanner and go to Settings (gear icon in the top-right corner).

Tap on “Adapter” (in old versions – “Connection”)

Select Connection type: Wi-Fi

Make sure that you have correct adapter IP address and port. For most cases it’s IP address is 192.168.0.10 and port is 35000, but some adapters have different settings, so you should check documentation that comes with your adapter.

That’s all! Now all you need to do is tap on big green “Connect” button that’s located.

When you want to connect next time, just make sure that you’re connected to OBD2 WiFi network and tap on “Connect” button.

 

 iOS Wi-Fi connection troubleshooting

 

Configuring Bluetooth 4.0 (LE) connection on iPhone/iPad

First of all, make sure that you have an OBD2 ELM327 adapter that works via Bluetooth 4.0 (LE). Pay attention to the Bluetooth version! Apple iOS devices support only Bluetooth 4.0 adapters. Older Bluetooth adapters are not supported. This limitation of the operating system Apple iOS. For more information, read article about choosing propper ELM327 adapter.

You need to insert the adapter into the diagnostic socket (also known as the OBD2 connector) and turn on the ignition or start the engine. If your adapter has a power button on the case, press it.

Make sure that Bluetooth is enabled on your iPhone / iPad.

Attention! Unlike Android devices, you don’t need to setup pairing with adapter in the iPhone / iPad system settings!

Step 1: Launch the Car Scanner and go to Settings (click on the gear icon in the upper right corner).

Step 2: Select “Adapter” (in old versions – “Connection”)

Step 3: Select “Connection Type”: Bluetooth 4.0 (LE)

Step 4: Click the “Select Device” button. You will be taken to the Bluetooth LE (4.0) nearby device search window.

Step 5: Wait until your adapter is detected and click on it. If the adapter is not found within 5-10 seconds, click on the “Update” button to retry the search.

Usually the adapter is called “OBDII”, “obd2” or something like that. If this is a branded adapter, then its name can be similar to its brand (for example “Viecar”, “VLink”, etc.). Please note: adapters are never called as a car brand, “MY CAR” or something similar. And, the adapter always has a name. Devices without a name, only with the address of the form {…} are not adapters.

Attention! If after several attempts your adapter is not discovered, it means that it has an outdated (<4.0) version of Bluetooth that is not compatible with Apple iOS.

Step 6. Select your adapter in the list of detected devices and wait for the compatibility check with Car Scanner.

That’s all, connection setup is complete. Now you need to click on the big green “Connect” button on Car Scanner main screen.
