OldMoofKit

import OldMoofKit

let bike = try await Bike(username: "Johnny Mnemonic", password: "swordfish") // queries the vanmoof web api
try await bike.connect()
try await bike.playSound(.bell)
try await bike.set(lock: .unlocked)
bike.disconnect()

OldMoofKit is not an official library of VanMoof B.V. This Swift Package hasn't reached an official stable version, so some features may not work as expected. You use this library solely at your own risk.

• Establish a bluetooth connection to a VanMoof Bike using async/await
• Lock or unlock your bike
• Change the bike settings: light, motor assistance, ...
• Combine support to react to value changes

To integrate using Apple's Swift Package Manager, add the following as a dependency to your Package.swift:

dependencies: [
    .package(url: "https://github.com/Jegge/OldMoofKit.git", from: "0.0.3")
]

Or navigate to your Xcode project then select Swift Packages, click the “+” icon and search for OldMoofKit.

As the OldMoofKit is using the CoreBluetooth framework to establish a BLE connection to a bike the NSBluetoothAlwaysUsageDescription key needs to be added to the Info.plist of your application.

<key>NSBluetoothAlwaysUsageDescription</key>
<string>Establishing a bluetooth connection to your VanMoof Bike.</string>

To initially get a bike, connect to the VanMoof web api and retrieve the first bike.

let bike = try await Bike(username: "Johnny Mnemonic", password: "swordfish")

If you own several bikes, you need to download the details separately.

var api = VanMoof(apiUrl: VanMoof.Api.url, apiKey: VanMoof.Api.key)
try await api.authenticate(username: "Johnny Mnemonic", password: "swordfish")
let allDetails = try await api.bikeDetails()
let details = allDetails.first! // select one element from allDetails
let bike = try await Bike(scanningForBikeMatchingDetails: details)

If you already have your bike details, e.g. because you have downloaded them earlier from the VanMoof site, you can construct the bike details manually.

let details = try BikeDetails(bleProfile: .smartbike2016, macAddress: "12:34:56:78:9A:BC", encryptionKey: "00112233445566778899aabbccddeeff")
let bike = try await Bike(scanningForBikeMatchingDetails: details)

Note: Make sure that you've got the bleProfile, the macAddress and the encryptionKey correct, otherwise the connection will not be established. The other parameters are solely flavour text.

Note: The MAC address has to be entered in MAC-48 format.

Note: The encryption key has to be exactely 16 bytes long and has to be entered as hex string.

Bikes implements Codable and thus can be serialized / deserialized should the need arise.

// store a bike as data
let data = try? JSONEncoder().encode(bike)

// read another bike back from data
let otherBike = JSONDecoder().decode(Bike.self, from: data)

Connecting a bike is straight forward, just call the connect method.

try await bike.connect()

The bike will stay connected (and in fact automatically re-establish a broken connection) as long as you do not manually disconnect it.

bike.disconnect()

To retrieve the current connection state, query the bike's state:

let state = bike.state
switch state {
    case .connected:
        // do something when connection get (re-)established
    case .disconnected:
        // do something when connection drops or closes
}

You may also subscribe ot the statePublisher and be informed when the current state changes.

let subscription: AnyCancellable = bike.statePublisher.receive(on: RunLoop.main).sink { state in
    // react to state ...
}

subscription.cancel()

Note: Make sure to receive the state changes on the correct thread.

Note: When disconnecting, do not forget to cancel your subscription.

The bike has a dedicated errorPublisher, that you can subscribe to to get error messages.

let subscription: AnyCancellable = bike.errorPublisher.receive(on: RunLoop.main).sink { error in
    // react to the error
    print("Error: \(error))
}

subscription.cancel()

Note: Make sure to receive the state changes on the correct thread.

Note: When disconnecting, do not forget to cancel your subscription.

The bike has all kind of properties that represent the current known state of the bike, as:

• lock (locked, unlocked)
• alarm (on, off, automatic)
• lighting (always on, automatic, off)
• batteryLevel and batteryState (percent charged and charging or discharching)
• moduleState (sleeping, off, on)
• errorCode (raw data, depending on the bike model)
• motorAssistance (off, one, two, three, four)
• mutedSounds (wake up sound, shutdown sound, lock sound, unlock sound)
• speed (current speed in km/h)
• distance (distance in km)
• region (eu, us, japan, offroad)
• unit (metric, imperial)

let lighting = bike.lighting

Note: if your bike does not support a properity, it's value will be nil.

For each property there is an associated Publisher that allows monitoring changes of value.

let subscription: AnyCancellable = bike.lightingPublisher.receive(on: RunLoop.main).sink { state in
    // do something when lighting changed ...
}

subscription.cancel()

Note: Make sure to receive the state changes on the correct thread.

Note: When disconnecting, do not forget to cancel your subscription.

Each property is complemented by a setter. Calling this setter transmits the value directly to the bike. The bike then will send a notification and the according property will get updated upon receiving that notification. If your bike does not support a property, calling the setter will be ignored.

try await bike.set(lighting: .alwaysOn)

Note: setting the region of your e-bike to a value not corresponding to your country may be illegal in some jurisdictions. Use at your own risk.

try await bike.playSound(.bell, 3) // play the bell sound thrice

try await bike.set(backupCode: 123) // sets 123 as new backup code

Sometimes the bike may not immediately react to configuration changes, because it's smart module is sleeping. To make sure that your command gets executed even after the bike went to sleep, you can wake it up again. When wakeup returns, the command has been sent to the bike. It may still be on .standby at this moment. To be sure that the bike is awake, consider listening the the moduleStatePublisher.

try await bike.wakeup()
