V3.0​

Notice: This version has breaking changes

Before​

The management of Bluetooth keys was handled by the SDK, which communicated with the Cartrack servers from the initial version to version 2.4:

  • Obtaining the key
  • Key randomisation

This increased complexity for mobile integrations, and keys could only be fetched (or randomized) while the smartphone had the app open. In many cases, users may be in environments with limited cellular connectivity (for example, parking garages), which made the process cumbersome.

After​

This new SDK is more straightforward, and we have exported the key management into the Cartrack Fleet API. Using the API, you can now fetch the BlueTooth keys ahead of time and reuse them for multiple bookings. Have a look at the following endpoints:

  • GET /mikey/:registration, to get the key for a given vehicle registration

  • GET /mikey, to get the keys for all your vehicles

  • POST /mikey/:registration, to randomise the key for a given vehicle registration

  • API documentation: https://developer.cartrack.com/fleet-api

To enhance security, it is advisable to randomize keys periodically. We suggest rotating keys when there is enough time between two users, allowing the vehicle to receive the new key and the user to load it on their phone.

You can then provide the key to the user’s smartphone using the SDK key functions.

  • BleListener.onSaveAuthKeySuccess called when save authentication key successfully
  • BleTerminal.saveAuthKey, BleTerminal.getAuthKey and BleTerminal.removeAuthKey to handle authentication key

V2.3​

  • Added a function BleAction.unlockNoKeyFob to send an unlock command Unlock_0 that doesn't activate the key fob. The driver won't be able to start the engine.
  • Receive BleAction.unlockNoKeyFob response in BleTerminalDelegate.bleTerminalDidAction(terminal:action:error:)

Download 📦​

V2.2.1​

  • Add BleTerminal.removeAuthKey() to remove authentication key from local memory
  • Add BleListener.onRemoveAuthKey(error: String?, success: Boolean?) to receive a call back when removeAuthKey() called
  • Add BleTerminal.randomAuthKey() to random the terminal authentication key , call back will be received in BleListener.onGetAuthKey (error: String?, success: Boolean?)
  • We now have two separate functions removeAuthKey and randomAuthKey, please consider it when upgrading to this new version.
  • The Shared Preference will only save one authentication key with a static name. If you want to use another it for a different vehicle or a new authentication key, you will need to remove the current authentication key before fetching the new one.
